Infiniti - Ex35 :: Sludge - Car Initially Stalling / Running On 5 Cylinders Instead Of 6

Feb 8, 2011

I have a sludge problem with this a 2008 infinity EX 35 . The car was initially stalling and had been in service at the dealership several times . Error codes were present and they didnt know what the cause was . They replace spark plugs and tried to find a bandied rather find the cause , Now they are claiming they cant do anything for the sludge issue and blaming it on poor maintenance .. the oil was changed ever 3000 . they have the records of this also. They talked about flushing the engine , but stated it doesn't work Is this vehicle prone to sludge . Its only running on 5 cylinders instead of 6 per dealer.

2005 Camry LE with 4 cylinders , the problem now is it will stall after warm up. To drive it to 60mph speed, it will take 2 time than normal. very slow accelerating.

Will stall after 20 second car complete stop, and will not turn over after 5-10 minute later. I had all 4 new Denso spark plugs and Fuel injectors, clean Maf sensor, clean throttle body, replace coolant temperature sensor.

Toyota - Supra :: 1985 Running On 2 Cylinders (First And Last)

I have a supra that is only running on the first and last cylinder. It was running poor and I pulled off the spark plug wires to see how it ran. After more testing I removed all 4 middle plug wires and it kept running the exact same. What would be causing this? The plugs and wires are new.

Elantra XD (2001-06) :: Running Rough Like On 3 Cylinders

Friend of mine has a 2001 Elantra, not sure of the mileage but it started running really rough, like it's on 3 cylinders. His mech wants to look at the head, thinks there's a broken spring or something.

I asked if the timing belts ever been changed, no it hasn't. My suggestion is it might have lost a few teeth from the belt and jumped. I can't see it being a broken valve spring or something worse because the beta engine are tough as nails.

He said the wires are fine, they probably need replacing too because my friend is the type of person who changes oil and that's it.

Golf/GTI VI :: EPC Light Came On - Engine Now Running Only On Three Cylinders

Last night I was cruising at about 55 when the EPC light came on. At first, I didn't feel anything unusual, but shortly after exiting onto a surface street the engine was definitely running on three cylinders. I immediately turned around and drove the four or five miles home (still on three cylinders) and parked it.

My car is a 2011 with 21K miles. I had an APR flash (Stage 1) done about 2 months ago. (I'm not saying that there's necessarily a connection.) What might be going on? I plan to take it to the dealer tomorrow after resetting to stock program (though I understand it can still be detected). Is it okay to drive it? (Assuming that it will start.)

Santa FE SM (2001-06) :: Rough Running While Driving / 2 Of 4 Cylinders Lost

2001 Santa Fe with 2.4 engine auto FWD 198k miles. When it is started first in the day, the engine sounds good and shifts well. After a few minutes and also after stops, first gear works well but then the following gears do not work well almost as if the engine and the transmission quit talking to each other. Traveling at 60 mph starting up a medium hill, the car downshifted and could not pick a gear. Although I pushed the pedal harder, the car did not respond rather continued to slow down. It acts like I lose 2 of the 4 cylinders in all cases. I replaced the spark plugs and two of them had oil on top of the plugs and also all around the threads. I replaced both coils thinking that one of them was the issue but no change has been observed. I replaced the throttle position sensor; no performance change. I do not believe it is the transmission as I have not notice any clunking, or bad shifting when starting out. While coasting at 40 mph in neutral and my pedal pressed at a certain position, the rpm gauge fluctuated from 3k to 3.6k many times for the duration of 20 seconds.

Nissan :: 1986 - Stumbling Like Running On 3 Cylinders When Started Cold

My 1986 Nissan 300ZX Turbo has 60,000 careful miles on the odometer. It began stumbling, like running on 3 cylinders, when started cold. Time of day and moisture make no difference. New Cold Start and Air Flow Sensors have worked a little, but it still has the stumbles about half the time when started cold.

Pontiac - Grandprix :: Acceleration Cut In Half / Maybe Running On Fewer Cylinders?

1995 Pontiac Grand Prix GTP 6 cylinder 3.4L 100,000mI'm not sure how to describe this any better, but while driving down a 55mph road my acceleration suddenly crapped out. I could still get it to go, but I had to put the petal to the floor to get there. Engine was a lot quieter, didn't have the same pep to it at all. No overheating and didn't notice a change in oil pressure. I've got a diagnostic appointment tomorrow but thought maybe I could get some ball park figures before I get there.

Audi - A4 :: 2001 - Misfire On All Cylinders And Car Appears To Be Running Lean

I have a 2001 Audi A4 1.8t (AWM engine, B5 platform). When I start the car, I get misfires on all cylinders (very rough idle, sometimes it stalls when the engine is cold) and the car appears to be running lean. Once the CEL comes on, it runs fine (albeit the slight loss of power do the ECU going into limp mode to correct the problem).

So far, I've done the following myself: new O2 sensors, new SAI pump, new EGR valve, new diverter valve, new N75 valve, new vacuum hoses, cleaned the throttle body, new MAF sensor, cleaned the air filter, new plugs, and new coils. When the problem persisted, I had my mechanic change the timing belt, check for vacuum leaks, change the valve cover gasket, replace the fuel pump and filter. None of this has solved the problem! This is driving me nuts.

At this point, there are only two possibilities that I can think of:

1) Catalytic converter is clogged? I pulled out the pre-cat O2 sensor, started the car, but it still misfired. This seems to mean that there's another problem (i.e., if the cat is clogged, it's in addition to something else).

2) Dirty fuel injectors? I've put two bottles of Techron through the car to no avail. From the outside, they look pretty dirty, so I'll definitely try removing them, cleaning them, and replacing the gaskets. Hopefully this solves it.

Is there something I'm missing?

Mazda - Miata :: 2000 - Car Running On Two Or Three Cylinders / CEL Came On And Continued To Flash

Car recently acted like it was running on two or three cylinders and cel came on and continued to flash. The shop that did the repairs is no longer a Mazda dealer, but has a factoy trained tech. Don't know the code #, but was told that there was a low voltage code, and a misfire code. The battery was replaced, throttle body cleaned and a new fuel filter installed. The cel came back on about 25 miles later. They rechecked the codes. Said it could be the converter, and cleared the code again. After about 150 miles, the cel came on again but the car ran normal. Talked to the shop again and was told the the converter problem would have to be serviced at a Mazda dealer. The engine did the running on three cylinder thing again. Since then, it seems to run ok but the light is still flashing. If the OEM converters are fragile are there better options for replacement? The car has 30,000 miles.

Ford F-150 - 1997-2003 :: 2002 Truck Running On 3 Cylinders

My aunt recently gave me her 02 f150 for free because it got flooded and she didnt want to fool with it. she said it ran great before it got flooded. I flushed everything. oil, gas, and tranny. I blew water out the cylinders and replaced the spark plugs. I took the fuel injectors out and cleaned and cycled some b12 threw them. The truck starts and gets spark to every cylinder and is only running on 3. I can pull 3 plug wires off and the idle does not change. Idk what it could be but dead cylinders. I am afraid I am going to have to find a new engine. I am going to do a compression check later this week when I have time. I am new to fords so if there is anything I should check...

Subaru - Forester :: 1999 - Getting Error Code P0325 Now Running On Two Cylinders?

I took my car to my previous shop for a P0325, Knock Sensor Circuit Malfunction. They wanted nearly $500 to fix it. My new shop said that I just needed some engine treatment and the code went away for a week and a half, but it came back yesterday, and my engine ran a little rough.

I heard what sounded like a very rough engine and it was my car. The technician came in saying that I was only running on two cylinders, but that sounds like far worse of a problem than I had been experiencing. They say that I need a $266.80 valve adjustment, which is all labor, but the total is $300 more than that:

Engine Light diagnostic: $44.99 Shop Fee: 35.00 Tune up package Remove and replace spark plugs: 60.03 Additional access time - remove: 64.20 and replace spark plugs: NGK Spark Plugx4: 9.96 Adjust Valve Clearance: 266.80 Pepguard Limited Extended Labor: 58.65 Warranty BWD Custom fit ignition set: 36.39

Parts: 46.35 Labor: 436.02 Other: 93.65 Tax: 6.55 Total: 582.57

Of course, my roommate, who is upset that I am not continually pouring fluids into leaky power steering and AC systems butted in and said the entire thing is preposterous. Problems with cylinder firing are invariably the result of bad spark plugs andor wires.

Well, they say that I need to replace those, which cost $46.35, the least expensive entry in the entire estimate. They just want to charge $124.23 to replace them.

Why don't I replace them myself and see if that fixes my problems?

They say that if the valve clearance adjustment does not fix the problem then I need new cylinders and valves.

Regretfully, I have a "service plan:""Engine: All internally lubricated parts contained within the engine block, cylinder head(s) or rotary engine housing(s); oil pump; timing belt or chain, timing gears and timing tensioners; water pump; engine block, cylinder barrels, engine head(s), rotor housing(s) if damaged by the failure of an internally lubricated part. Dipstick and tube; harmonic balancer; oil pan; timing chain cover."

I cannot imagine that it would cover a valve clearance adjustment and they would only cover cylinders and valves "if damaged by the failure of an internally lubricated part."

So, ride my bike eight miles tomorrow, replace the spark plugs and wires, and hope that it is enough?

Golf IV / Jetta IV :: Running Rough And 3 Codes Stored - Cylinders 2 And 3 Misfire

So my daughter's 2000 Golf Mk4 with 160,000 miles on it was running rough and had 3 codes stored - cylinders 2 & 3 misfire and a 411 secondary air injection problem.

Having had the misfire code before I swapped injectors around and the error code moved cylinders with the injectors so I attempted cleaning them and also cleaned the throttle body and intake manifold. At this point car still running rough but also started smoking badly.

Replaced the following items:

- Spark plugs
- Spark plug wires
- PCV valve
- PCV hose
- Fuel injectors w/ remanufactured

Hose reconnected between secondary air injection pump and air intake - previous owner had duct-taped it in when he couldn't get it to seal I guess. I've never heard it run.

Car running better, idles more smoothly, doesn't stumble or stall like it did before, no error codes coming up BUT car smokes a lot and the fumes make me feel sick just driving it a mile.

The car had never smoked like this before, hasn't had a whole lot of love the last year or two but no real problems either so why the sudden smoke?

At first I assumed it was cleaner being burned off but that should have been gone in under a minute and this is on-going. It's bad enough to not only be embarrassing but apparently dangerous as the fumes are bad.

Ford Fuel System :: 1986 F150 - Engine Is Running On 4 Cylinders 1 / 4 / 5 And 8

What to do next. Engine is running on 4 cylinders, #1, 4, 5, 8. Had a mice nest on top of injector #2. Removed mice nest. The mice had chewed through wire for #2 injector and caused bear lead rubbing on the block. One lead rubbed through. Repaired, splised in a wire. Also changed rotor, rotor cap, all sparkplug leads and plugs.

Compression on all 8 cylinders measured to be above 160 psi.
There is spark to all 8 cylinders, including the other 4 cylinders, 2, 3, 6, 7 that is nor developing power.

Fuel rail pressure is 35 psi on idle and spikes to 43 when reving the engine.

The fuel injector resistance all all measured injectors are the same (about 14.8 Ohm). Measured injector # 1, 2, 5, 6, 7, 8. Injector # 3 and 4 is hidden and require too much disassembly. Visual inspection deems wire for #3 and 4 injector to be ok on top of block.

Electric impulse (tested while engine was running) to injector # 1, 5 and 8 are ok, used test lamp to see that there are electric impulse to the injectors. Injector #2, 6 and 7 does not have any electric impulse. Unable to check electric impulse to # 3 and 4. However cylinder #4 develops power. Used moving the sparkplug wire for cylinder #4 to verify that is is developing power.

What would my next step be? Where should i look next?

1. Where is the control module and is it likely to fire to only 4 cylinders
2. Could it be an wire in the pickup element, under the distributor. All wires seem intact.

Ford Excursion :: 2001 V10 Not Running On All Cylinders / Check Engine Light Is Not Coming On

Bought a fixer upper 2001 v10 and it's definitely not running on all cylinders. Also the check engine light is not on and the PCM is not saying it's on (per my code reader) and it doesn't come on when I turn the key on.

Is it possible the previous owner had a programmer of some sort to disable the CEL? If the bulb were removed my scan tool would still show it on. Trying to get it to tell me which cylinders I am having trouble with.

Ford 7.3L Power Stroke (1999-2003) :: Truck Running Rough And On Less Than 8 Cylinders

I had an HPOP line burst and soak the engine compartment with oil. I replaced the line and degreased the engine and rinsed it off. I started the truck and let it idle for 15 minutes or so before driving it. On the way home right after a shift it started chugging and running terribly. The check engine light was on as well. I limped it the mile or so home and shut it off. I restarted it and it runs just fine. I checked the DTC's with Forscan and there were a bunch of things that were mostly related to the HPOP and the MAT sensor that was shredded when the line blew. I left the hood open to dry out today and I'm hoping it is just some water in a connector. Does that sound plausible?

C/K :: 1994 1500 5.7 Liter Engine Skipping / Misfiring - Truck Running On Half The Cylinders

My truck is skipping but if I give it more throttle it will stop but then will start back when I let off the throttle. It seems like it is only running on half the cylinders. This problem is intermittent which makes it very hard to troubleshoot even for the dealership and other places I have taken it. Also, the problem is temperature sensitive. It only does it below 40 deg. F. Truck runs fine any other time of the year. Truck has new plugs, plug wires, distributor, egr valve, O2 sensor. Also, the IAC has been cleaned. The check engine light does not come on.

I have a buddy at work who has an 04 f350 6.0 that is running very rough. we put a scanner on it and disabled the injectors and 1,7,8 have no change. He checked the FICM voltage and is getting 48 volts on crank and run. He checked the wiring for anything loose or rubbed but nothing seems wrong.
