'91 buick, 3 spd. 0 acceleration in 3rd, trouble code says TCC curcuit. Lopes @ idle when warm, runs rough @ times. many new sensors, timing chain & sprockets, still, the loping.
View 1 RepliesI've had a 1991 buick skylark for 3 years, just hit 100,000 miles, and for the past few months i've been having problems with it stalling out/misfiring when I press the gas, almost like a lawnmower running out of gas, and then catch and go fine. it was only happening at the 3rd gear change,(randomly but only at that change), and then it started happening only at the 2nd gear change. it first happened at the end of a long road trip, and the speedometer and odometer stopped working at the same as well, but have since returned. but now it's been happening on cross town trips.
Every time it has happened has been random, and it always corrected itself and was fine. but this last time, it was doing it consistently, at random gear changes and from idle. it finally gave out at a stop sign and it barely stuttered across the intersection, but with the check engine light on and never "catching on" or actually dying/cutting off. I took it to my local shop, and they ran all the computer test and road tested it and told me they couldn't find anything wrong. they tested the fuel pump, which had good pressure. They mentioned it might be the module, but were honest and didn't want to charge me for something they couldn't tell was actually wrong. any clue?
I have a 1991 Buick LeSabre, sometime last year the check engine light came on, and I took it into a mechanic who told me that a magnetic sensor on the timing gear broke off and that it is the problem with the car, but it would cost me 500 dollars to replace the part, because it is located in the engine. I noticed that the engine felt like it lost power, and the car started vibrating when I was idle. The beginning this year, I replaced the spark plug wires, and replaced the spark plugs, when I replaced the spark plug wires, I realized that two of the wires were broken, as soon as I was done.
I tested the car, and the power is back, but I still have the stalling problem. I will try to describe how the car stalls, I come to a stop, and when I push on the gas to accelerate, the car just conks out, so I have to restart the car, and rev it a little to keep it from conking out again, and it starts running normally. I have been told by another mechanic that I need to replace a Electronic Ignition Control module, which I can not find, and that it is possible the fuel is not getting into the chambers. I just want some answers to my problem, so the car will last me till I can get a new vehicle or something better.
I have a 96 buick skylark. I just recently had the parking pawl fixed because it was broken. Now when I slow down the engine idle seems to start looping and almost stall, it in fact has once. As I slow down, and I can feel the car somewhat trying to pull forward as if its not down shifting correctly. when I finally get stopped the idle will come back up and idle normally. the car upshifts great. I know that one of my rear wheel speed sensors has a broken wire.
View 3 RepliesI have a 2000 VW Passat with the 1.8L turbo. When I bought it, the timing belt was off 1 notch. After I fixed the timing issue the car still didn't idle well. I was told that the throttle body was causing the problem so I replaced it. The car ran good for about 5 minutes after I replaced the throttle body. After I hooked up a OBD-II scan tool up to it instantly started running rough. The car runs at 1100 rpm at a cold start-up but when the car warms up it idles down to 850 +-75 rpms. I cleaned the MAF sensor, and it still runs rough. Car has 180,000 miles and MPGs are also down.

View 1 RepliesThis 97 Buick will turn over and the engine will catch but then dies. It doesn't do this all the time. Also, the anti theft light comes on during this starting problem.
View 3 RepliesMy son drives a 2003 Ford Focus with 183,000 miles on it. At random times when he starts the car, the engine runs very rough at idle speed but when he drives away, it runs fine until he slows for a stop sign/turn, etc. and the engine is at idle speed again. When this happens, the engine runs so roughly, that he loses vacuum to the brakes and his brakes stiffen dangerously. The car may not do this at all for a couple of weeks of driving, and when it doesn't do it, it runs beautifully.
Also, it only runs like this if it does it from start-up; it never idles roughly in the middle of a drive in which the car started normally. I have changed the spark plugs and wires, PCV valve, fuel filter, and air filter, but it still goes through this about once a week. I bought the car used just a few months ago and it had just had the valve cover gasket changed because the valve cover was leaking.
The engine problem I am having is with a 96 corolla with about 198000 miles on it it runs rough and has lifter noise as if there was no oil in engine it only happens when cold and when the vehicle has sat for more then 3 days since last use.....
View 2 RepliesI have a 95 skylark 4 cylinder, i have what appears to be a coolant leak from the thermostat housing and i also have coolant mixing with my oil. Can the leak from the housing cause the coolant to mix with the oil? If not what else could be the issue?
View 3 RepliesI have a 1997 Buick Park Avenue with a 3800 series II motor that runs perfectly in dry weather. However, in wet conditions, rain melting snow, etc. it will begin to miss and throw out a P0300 OBDII engine code. This is the code for multiple random misfire. If I leave it to idle on its own it will get worse and die out right. Sometimes restarting it is an option though it still runs rough, but I can limp it to somewhere I can work on it. I think its electrical, since it doesn't seem to get the spark it should though fuel doesn't seem to be a problem as you can smell it after a bit of cranking.
I've been battling with this thing for over a year so far and have replaced the following, ECU, all 3 coil packs, spark plugs/wires(newest parts), mass airflow sensor, cam position sensor, ERG?(emissions deal I believe, mechanic friend put it on) valve. I had the battery trickle charged and tested at an Autozone, I haven't had the alternator tested yet.
Its a very frustrating problem, as far as I can tell I've replaced everything on the ignition system with the hopes that it did the job only to get stranded during the next long rain. It does take quite a while in wet weather for it to start acting up, but once it starts missing a little bit, it doesn't stop until the entire engine compartment has had a few days to dry. Engine temp doesn't seem tosolve the problem dry out. I'd also like to note that I've noticed on this latest trouble that the interior lights have been flickering and headlights too. It may have been doing this earlier, but I hadn't noticed if it was. I'm going to check what kind of voltages the alternator is throwing out next time I have it running.
I'm working on my sons 1985 Celica GT 22RE. He was having problems with it running rough.
I've isolated it down to the number 1 cylinder being starved on warm starts. If you cold start it the problem does not occur but if you let it sit warm for 15 minutes it will fire up but nothing from number one cylinder. Lots of spark but no firing. So I'm going to tear down the EFI and move the injector to see if the problem follows it. Will probably see if I'm getting any voltage to the injector while rough before tearing down.
I can't find anything about an injector not working once warm so I'm thinking it may be an ECU problem.
I just had my 72 Skylark tuned up, when I start it and put it in gear it makes popping noise and stalls, I restart and let it run a for a few minutes and it will finally go. Once it is warmed up in runs great. What causes this stalling problem,? I guess I'm too old to remember.
View 4 RepliesWe just replaced instrument cluster and turned the key to on position for 10 minutes. We waited for the anti-theft light to quit flashing and the car runs great but the anti-theft light will not go off. How can I fix this problem?
View 4 RepliesAbout 2 weeks ago my 1997 Buick Park Ave (115,000 miles) began running bad during a heavy rain storm. It was running fine. Then all of a sudden at a stop light the motor hesitated and wanted to stall. I nursed the gas peddle and limped home and turned the car off. The car hesitated and sputtered all the way home as if I was running out of gas.The next day the car would not start. It turned over but would not start. I tried starting the car for three days. My mechanic friend later diagnosed the car and stated the computer was not functioning correctly. He replaced the computer. The new computer seemed to correct the problem.
The car ran great for the next 2 weeks. Yesterday, it was raining hard while I drove the car about 150 miles without any problem. Then suddenly again the motor started running badly. Again, the motor wanted to stall and hesitate as if I was running out of gas. I limped home again. This morning I tried to start the car without any luck. In addition to installing a new computer, In the last 2 months I have changed all the fuel injectors and installed new spark plugs.I have also changed the fuel pump and repaired the fuel tank. My mechanic say the cam sensor and crank sensor are operating correctly. There is spark coming from the coil packs and to the spark plugs. I do not want to randomly change parts.
I have a 1997 LeSabre with 180000 miles. I can drive the car for 4-5 miles before it stalls and then dies. the car will start to idle fast, then bottom out a couple of times before it dies. It also makes a horrible noise under the hood and sounds like the rods are all clanging together. Once it dies, it will not restart until it has sat there for 30-40 minutes. After sitting for some time, it will crank right up and then repeat the process again. My oil pressure is off the chart high and it stays there all the time. Does this have something to do with the problem of is that another problem all together? What is causing my car to die like this and how do i fix it?
View 5 Replies2004 F250 V10, runs good until it warms up whether it's hot or cold outside. While on freeway, it really shakes while cruising, but of you get in the gas enough for a kick down, seems to be pretty smooth. I've changed the coils, and 9 plugs (one wouldn't budge, but the others I took out looked fine) to no effect. Where else should I look? Also, no CEL, and no codes, which seems odd as bad as it feels...
View 11 RepliesI have a huge problem. My 94 ranger 2.3L 5 speed manual transmission, has problems with idoling while it's cold, has no power going uphill and stalls when I slow down to stop. This is all after putting a new motor in. The old one was running ok with 310,000 but lagging bad. I figured with the driving I do, a new motor wouldn't be a bad thing. Boy, was I wrong. It has been a nightmare. But once the truck is up to operating temperature, it runs so smooth you wouldn't think there was a problem. But let it cool off, restart, and boom! There it is. We have changed so many parts and sensors with absolutely no change to the original problem. It's very frustrating. I just can't let this problem win. I will figure it out.
View 13 RepliesI'm working on a 06' Passat 2.0t and it runs rough only at idle like its misfiring only vag-com says no misfires and no engine codes. MAF looks like it may be a little low on performance but should be ok. I tried swapping out coil packs but no change. I changed the pcv breather and hose, cleaned the carbon off the valves, swapped the throttle body with a known good one, and changed the piston on the fuel pump and still no change. It smooths out when I turn the a/c on but that's the only thing that changes the idle.
View 7 RepliesI've taken it to a half dozen mechanics, none can diagnose the problem. From a cold start the engine idles well, but once it warms up and the fast idle setting shuts off, it begins to vibrate quite a bit. I rebuild that included an all new fuel injection system, new ignition parts (including distributor, replaced at a later date,) new wire to alternator (the old one had cracked insulation,) and a new mass airflow sensor (swapped in from a parts van-no effect.)
Basically everything is new except for the sensors (crank sensor, idle air, throttle position, etc.,) and the fuel filter and pump. I'm not getting any codes, and at least two mechanics said it had good fuel pressure. It FEELS like a vacuum problem on a carburetor vehicle, but I had the vacuum harness checked as well, and everything seems to be in order.
I have a 2000 Corolla with about 147,000 miles. At idle it runs very rough, but can accelerate up to about 50 mph. Then it starts to cough and wheeze and run roughly again and won't accelerate any further. It feels like the engine will shake itself off its mounts, so I slow down and stay under 50 mph. I replaced spark plugs and a repair place hooked it up to a computer. They then told me it needed about 1800 dollars worth of repairs to replace the valve cam I think they said. I'm skeptical and wonder if it just needs a tune up, . It has not had one since I bought it at 128,000 miles, and II don't know how long it had been prior to that.
