Lexus IS 2014+ :: RX300 Misfiring And Running Rough
Dec 27, 2014
My 1999 lexus rx300 first threw a P1135 following a P0125, I tested the sensor and it was open at the heater circuit then then I was waiting the new part in the mail and during that time it kept running rough and then it threw a P0300, P0301, P0305, P0303. I was thinking that the PCM cannot monitor A/F ratio without the sensor so maybe the injector base pulse width was good enough. The misfire is are on bank 1, same as the bank 1 A/F sensor.

I bought my 2012 Camry, with 12,000 miles from the Dealership in December of 2013. The car was sold as CPO, car was purchased on Dec 30... just 6 weeks ago and I have had numerous issues with the car Misfiring. When I arrived at the dealer, the CHECK ENGINE and TIRE TRACTION lights are one and the car is running very rough as acknowledged by the service techs. For the 2nd time now, I am told they are not able to recreate the problem, so they are not able to fix it.
This is my 4th Toyota and I have NEVER had this many problems with a Toyota. Did I get a lemon? Service tech says he can't fix it unless he knows exactly what's wrong. I am asking him to check the spark plugs, check the ignition coil...and his response is that they can't just go on a wild goose chase, they need to know what they are looking for. Does this sound reasonable?

My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.
I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl

I have a 2000 ford explorer. 4x4 v6. One day i started it up and it was running rough. It had real sluggish power. Then the check engine light came on. I hooked it up to the code machine. The only readout was number 3 misfired. I replaced the plug and all was fine. A few months it happend again. I replaced it again and it was fine. Well it just happened again. I replaced it again. It ran good to work but on the way back no good. Light came on again. Hooked up the machine it read number 4 misfired and number 2 bank lean. So I replaced number 4. It still runs like shit rough idle and no power. Give it gas it dogs out but then it'll kick in if i get on it. Thinking it maybe a vaccum leak or intake leak or o-rings.

My '99 Olds Intrigue was running rough & short on power. Autozone read a trouble code "random misfiring" (PM3000 I think it was). As suggested, I changed the plugs/wires and checked resistance on all three coils with no luck. Here's the real spooky thing: while driving down the street a couple days ago, the pipe between the catalytic converter & muffler separated, scaring me and sending all the children getting off the school bus scrambling for cover. There was no noise or odor prior to the 'drop out' - is there any chance that the one problems (a catalytic malfunction, or small leak in the area for instance) could be related to the misfiring? A mechanic - before the pipe plummeted - had suggested it might be an injector problem or the intake manifold but I figured that an injector problem would trigger a code.

My 05 was running rough and misfiring quite frequently. After much deliberation, I took it in for a diagnostic hookup. The dealer said my driver side cat was clogged. Lucky for me, I was just under the warranty period(79673 miles). I have had it replaced and I can feel a noticeable difference in the way it runs. Could a clogged cat have made it run that poorly or am is it just in my head that it is running alot better?

So Friday before last my ex laid down on me while i was headed to work. So I parked it in a walmart parking lot and caught a ride to work with a friend then had it towed home that evening. Problem i was having is it started running really bad, miss firing, smoking, and sounding real rough, but I wasn't getting any trouble codes. So after both uvch's, icp, ipr, icp pigtail, checking fuel for water contamination and pulling my hair out, i decided to check the oil and found it to be 4 quarts low. Talk about feel like a knuckle head.... While it was down it did receive a new water pump, a diesel site 203* thermostat, new billet thermostat housing, Gooch's Radiator Flush Procedure, and some fresh rotella etc.

Our Accent has just about 86k on it now, back in November it suddenly started running real jerky/rough, misfiring kinda thing. So I was able to drive it to my local repair shop and they found a bad coil pack on #3, so they replaced that and put in new plugs while they were doing it.
Just Saturday we were shopping about 20 miles from home and cranked it up to go home and started doing it again, pretty much identical symptoms, runs out normal at certain RPMs so I knew it was probably same thing...I was able to get it home and then took it in this morning and sure enough now #1 is shot. So they are replacing that. They want about 30$ more per coil then I can order them for myself online so I didn't want to scarf up the money for the other 2 that are still original.

Recently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.

I have a 2013 Hyundai Azera with the 3L V6. I only use 93 octane gas (as recommended) and only use either Shell or Chevron. Each day, when I get in the car for the first time, I can count on it running rough and having inconsistent performance and some minor sputtering or misfiring (don't know the difference) until the car gets warm. Once it gets warm, all is well. It has 24k miles. Any thoughts on what may be the root cause? Should I change the fuel filter so soon? Does that matter being it gets better when it warms up?I change the oil religiously whenever the computer in the car tells me it is time to do so and use Mobil 1 synthetic.

How this is still happening. My gf's '14 IS250 AWD has had 3 misfire code that popped up at about 8.5k, 13K, and 15k miles now. First time it happened it wasn't severe, it vibrated a bit and engine light lit up. Took it to Openroad Lexus of Richmond and they said it's a random misfire code and no other troubling codes came up. They suggested maybe it was bad gas. So they reset the ECU, cleared the code and we went on our way.
Fast forward to 13k miles, only about half a year later, it happened again, except it vibrated vigorously and the engine light is flashing. So we had it towed back this time and have them look at it again. Codes were random misfire and misfire on cylinder 3. Now this time they said the culprit is a bad ignition coil. So they replaced that and car is alright again.
At 15k miles, about 2.5 months from the last incident (a few days ago), same thing happened again. It even went into limp mode on a stretch of road that had a speed limit of 50 mph. So again we towed it in to the same dealership to have them fix it, yet again. Interestingly, the code is misfire in cylinder 5. The tech mentioned they tried swapped ignition coil and plug to see if problem will go away but it didn't so they checked the fuel injectors for fault. The injector was faulty and leaking. They saw lots of fuel in that cylinder so they replaced the injector with a new one.
She only ever gets premium for gas, so all that bad gas thing doesn't hold. And the car has always been serviced on time by Openroad Lexus of Richmond, according to their recommended intervals.

The VSC light came on at approximately 62000 miles. Took it too a mechanic who put it on computer, found gas cap loose, and reconnected hose under air filter however no code shows on the computer for a fix. The VSC light still remains on. Tried all the internet fixes; pulling fuse & disconnecting battery cable. The light goes out but as soon as I move the car it comes back on. Is there anything I can do to avoid a large dollar visit to the Lexus dealer since there are no driving or stopping symptoms with the car.

The truck always ran perfect till two days ago. went to start it in the middle of the day , it would barely start, when it did it was missing bad. then seemed to clear up a little after about 30 seconds but still missing. they thought they got some bad fuel. so they dropped the tank cleaned it all out and got new fuel, no change.
Him and a so called mechanic "kid from fire stone" played around switching coil packs around from the injectors with no change. He tells me that the two front cylinders , one on each side are not firing. that those two spark plugs are coming out fuel soaked after running the truck. He thinks it dropped a lifter or push rod popped out of place.
I took my A/E over and came up with codes p0106 - map sensor, and p0135 - 02 sensor. i cleared them and started the truck, shut it back off ran codes again. He also said they pulled the 02 sensor and it still ran the same.

2000 Lexus RX300 - door locks/acutators... the locks open and close perfectly with the master driver actuator lock unlock button or with the the remote IF the temp is 70 degrees or below. If the temp is above 70 degrees the the actuators for all four doors will NOT all lock..1-4 do sometimes....they vary from door to door, day to day , including the driver driver door. Actators are expensive. Because they do work when cooler it tells me they do work. Why not when warm? what do I need to do? This is my mystery

We have a '99 Lexus RX300 with 174,000 miles (the engine has 130,000). The check engine light has been on for 2 years. The first mechanic found it was an O2 sensor and said that we didn't need to really do anything as long as the car was running good. So we didn't. Apparently a new code appears when running a diagnostic for the evap. sensor or vapor canister...is that right??? We had the evap sensor fixed..or so we thought and than tried to have the vapor canister worked on but the mechanic said the light came on.
Recently, the car has started lurching or losing power when it's warmed up and when it's accelerating. So, we took it to the Lexus dealership and 2 things were suggested
1) the vapor canister had been installed incorrectly and
2) sounds like the transmission is going.
So I have 2 questions, I think,
1) What is going on with the check engine light?
2) Does this sound like the transmission is going?

I have a 2000 Lexus RX 300 with 235,000 miles. I have been having a challenge with the "check engine" light coming on. I have taken it to a reputable mechanic several times. I had the oxygen sensor replaced, and the light went out. I had an emissions inspection, and the light came back on during the test, but it still passed, and the inspection report commented that there was a communication error, but no other problems. Every time the light comes on my mechanic puts his testing equipment on and finds no problems. I am trying to sell the car, but I am concerned that any potential buyer is going to look a the high miles and the check engine light and get scared off. The car is in great condition and looks like a very well taken care of car.

I just bought a 2005 RX300. It has a DVD in the glove compartment, which is not originally from Lexus, connected with the navigation screen.
When I turn it on, it starts playing the disc. But I cant find how to activate it on the navigation screen. I don't get any audio as well.
Tried the MD1 button, but it plays my flash drive, which is also in the glove compartment. Also tried CD button in different ways.
I know it is individual depending on how they install these, but what to try? There is also an remote for the DVD, but also doesn't seem to do anything about getting the audio and video on the screen.

Currently I own a 2000 Lexus RX 300. I just had an oil change but there is a noise by the tires only when I accelerate. When I put my foot on the brakes it stops. I am at a loss. Where would the best place to ask and get the work done.

2002 Lexus Rx300. The recent problem that I have been having is that various times when I go to accelerate my car from a stop position, i.e. stop sign, red light, my car will act as if something is getting stuck at the front right wheel pulling my car to the right and not allowing me to accelerate. It will make a grinding sounding noise. I have to usually lift my foot off the accelerator, straighten out the wheel and then press the gas again for the car to move. Sometimes the action it strong enough it causes the 'Slip Indicator' light to come up on my dash. It will happen at almost every stop light so driving in the city it gets rather annoying. At long distances on highways everything is fine because I'm not in a stop and go situation. My mechanic can't seem to figure out what the problem is so nothing has been fixed about it.
