Celica :: 92 GT - Rough Idle And Jerking Sometimes During Acceleration
Apr 1, 2011
I recently bought a 1992 Celica GT with 250k miles on it. It has a rough idle and a couple other things that may or may not be stemming from the same thing that's causing the rough idle
Like I said, it has a rough idle and there is a bit of jerking sometimes during acceleration. The exhaust makes sort of a "put-put-put" or "chirping" sound at lower RPMs and the frequency of the sound corresponds to the engine RPM. I do know of a couple things that could be causing the rough idle and maybe even the jerking, but I'm not sure about the sound from the exhaust.
The cooling fans are hard wired to the ignition so they run constantly, so when it's cold out like it is right now it takes forever for the engine to warm up. Is there a switch somewhere that they are supposed to be wired through? Where would that be? Also, the previous owner did kind of a hack job of putting on a cold air intake and I think I may be missing some sensors, especially because it seems to burn more fuel than it should. What sensors are located on the air intake, or are there even some in the stock airbox itself? And would this possibly be contributing to the rough idle and the jerking?
Also, I do get some vibrations when stopped at idle so I think I may want to replace the motor mounts.

So, I was on my way back home driving through the middle of nowhere Utah late at night, when I had an injector tip crack. I was able to identify which one and unplug it so I could get to Grand Junction, CO (about 350 miles away) where I have family. After a power nap I started calling parts stores and found an injector from Advanced Auto Parts (I couldn't find a motorcraft reman, but I was restricted for time). Installed it and all seemed good so I hit the road again. However, nothing changed. It still had the bad miss (rough idle, jerking/bucking when the torque converter locks up) just like when I had the injector unplugged.
The truck is an early 2004 6.0. It's the number 4 injector. I finally got home and hooked up my AE scanner to discover a #4 injector circuit low P0270 code and circuit contribution/balance fault P0272. It's definitely missing because disabling it has no effect. This could be a loose connector at the injector or FICM, because I can't afford another injector right now.

I just bought a 92 Toyota Celica for something to play around with. It's got just over 200,000 miles and everything seems to run alright except there is a really rough vibration at idle. The vibration is so bad that it's almost visible. You can still feel the vibration in drive but it isn't nearly as bad.
Any clue at what could be causing the vibration? I'll try to get a sound clip or video uploaded ....

I have a 1991 Celica GT. 175K miles. The car recently developed an issue where it jerks back and forth at light throttle, sort of like a newbie trying to learn to drive a stick. It happens at pretty much any speed, but is less pronounced at the higher speeds (45 MPH). In addition, it will not idle at a constant speed and cycles between 1100 rpm and about 300... or kill.
I've taken the throttle body off and IAC valve off and cleaned them both but it didn't change the behavior. If I pinch the line to the MAP sensor, the idle straightens out at about 1100 rpm. Disconnecting the MAP sensor gives good idle, but no performance while driving, so not a solution.
Things I haven't done yet: check continuity on throttle position sensor, checked MAP sensor (how?).

I have a 1986 Celica GT-S with 50,000 original miles on it. Car starts perfectly fine in the morning, runs fine, no issues. Problem happens when the engine is warm, and I let it cool off for about 10 minutes or so, at that point, when I try and turn the engine over, it would sometimes turn over and idle very rough, or sometimes it would die and I have to give it gas to keep the engine running. Once I am able to get it in gear and drive, the engine rpm would recover and go back to normal. I have new NGK wires, denso iridium spark plugs.

The car: 1994 toyota celica GT 2.2L automatic
Here's the problem: car starts fine when cold. When fully warmed up, if i stop to go to the store or something, and then start it after like 20 - 30 minutes it will start and the idle will be fluctuating between 800 and 400 for a few minutes and then even out. sometimes it will actually start up and die immediately, in which case i can save it by giving it gas for a few seconds and then it's fine.
What I've done so far: plugs (NGK), wires, cap, rotor, fuel filter (toyota), (checked air filter. still clean), tried cleaning the throttle body and IAC with some deep creep spray while on the car (not much effect).

I have a 100% stock 2004 Celica GT ~125,000 miles. Over the last few months I have been getting a rough idle and stumble at low rpms. The other day the car would not restart after sitting for about 20 minutes. Only recently has it actually thrown a DTC. The error codes were for misfires (P0300, P0301,P0302,P0303, P0304). I don’t get a code every time but the problem seems to be more noticeable if the car has been ran for a while, sits for 20-30 minutes while in a store and then when I try to start it when I come out of the store is when the problem most often occurs. When it restarts it will stumble at low RPM and if I hit the gas it has little response and misses badly. I have never used a scanner until now. I am using a Autel MS509 scanner and I am not sure it is giving me the correct diagnostic numbers for the live data. I think the DTC are correct but the live data is questionable.
Here is what I have done so far.
- Cleaned IAC valve (completely removed and cleaned)
- Searched for vacuum leaks using carb cleaner
- Cleaned MAF sensor
- Replaced all 4 injectors
- Replaced upstream and downstream O2 sensors
- Replaced Coolant Temp Sensor
- Ensured cam tensioner is providing adequate pressure to the cam chain
- Tried 2 sets of new Iridium NGK plugs and a new set of Bosch Copper plugs
- Moved coil packs around
- New air filter
- New fuel filter
- SeaFoam through intake and gas tank. I have not mixed in the oil.
- Compression Test (1=190,2=190,3=160,4=178)
Things I have not done.
- Taken it to the stealership
- Fuel pressure test
- Valve Clearance
I am concerned about the compression test because according to the service manual it should be around 218. I was using a Harbor Freight compression tester and I am not 100% sure I had a good seal with the tester.

I have a 2001 Toyota celica GT auto. It has 120k miles. I seem to have an issue that really is not causing a problem except for annoyance. After coming to a stop the car seems to exhibit the signs of stalling (car idles rough, shakes a bit) however the car never stalls. Once I start driving all is well. Now I took it to the dealer and they replaced the Idle Air Control Valve which is under the throttle body. They said it was getting stuck and due to the higher mileage possible. It was replaced and the problem is still there. The funny thing is even though the car exhibits these stalling symptoms the idle does not drop below 500 rpm (both dealer and I have verified this).

Woke up to go to work and it started up with a rough idle, got a block down the road and it had a slight miss under acceleration. Guessing its a bad coil, I've got a spare featured I'd play I I mini miny moe when I get home unless.

I have some major problems with my explorer. The idle is rough and accelerating is rough also. If I nearly put it to the floor it almost seems like it studders the power. it will feel great for a second that feels like it's less power for a second then more and less and more and less. When I'm sitting at idle, it will idle fine then after a minute or so it will bog way down and shake the whole vehicle. when that happens I give it some gas and it comes back to normal idle then it does it again after sitting for another minute. I've replaced spark plugs, wires, alternator, oil change and some tires. I've been told by many mechanics it could be the IAC Valve or the fuel pump or the fuel filter or a vacuum leak.

2007 Sonata V6. He's spent many hours and a good chunk of change at the dealership trying to get it fixed and nothing has worked yet. They honestly have no clue whats wrong which kinda scares me.
First off here is his problem. Occasionally when he starts the car it will idle very rough and struggles to accelerate to 30-40mph. When this happens he pulls over and shuts the car off for a few minutes then it will run fine again. When all of this happens there is no CEL or any light at all that flashes or comes on the dash.
Here is a list of things that have been replaced
Fuel pump
Throttle position sensor
Crank sensor
Plugs, wires and coil pack

My 2011 Sonata 2.4L GDI has already 76k miles. Spark plugs were replaced around 75K miles, Air filter was replaced. Fuel treatment was done several time since ownership, Intake CRC for GDI was used once about 2K miles ago. The car is doing good until recently. When I accelerate the car acceleration goes uneven. It is not like hesitating but you feel like the car is taking it in steps. Sometimes the first run in the morning, the car idle feels a little bit rough but that's only in the morning. It has been like that for a month now. What do you think it can be? No Check engine light, no pending codes and nothing major except that. I really suspect a bad upstream oxygen sensor (Air fuel ratio sensor). What do you think?
A look through the intake shows a very clean intake. No signs for any carbon deposit. A Hyundai dealer checked the car and told me there is nothing to worry about. Just told me to buy more Hyundai fuel treatment (AKA Chevron Techron) which was done and still I feel uneven acceleration.

While driving on the freeway my car started to surge as if it was starving in fuel. I had to press more gas to go the same speed. My gas tank was at a 1/4 full so I pulled into the gas station to fill in gas. As I was leaving my car could not accelerate while pressing the gas pedal. I could floor the gas and it would go only five miles an hour! The engine temp was okay, no engine lights, and no weird smells. I was fortunate to be close to home and slowly made it letting cars pass me on the side. I called the road side service who towed my car to my dealer. They checked for codes, ran fuel injector cleaner twice through the system, checked the fuel pump, and the pressure on the fuel system, no problems. The third day they gave me a Sonata for a loaner and I allowed the service manager to drive my car to see if the problem reappeared. No problems found and I picked up my car today. The problem hasn't reappeared yet but I am keeping track of any rough acceleration or idle.

I have a 2008 Accent SE and I'm having some issues... The car was driving fine the other day all the sudden check engine light came on started flashing then and just stayed on. This happen before and the car was under warranty so the dealership fixed it but now it ran out and it's happening again. Anyway the car is running very rough at idle like the car shakes and acts like it doesn't want to run. Also when driving it honestly feels like the car has no power or acceleration what so ever. I replaced the air filter with a brand new K&N filter, I also changed the spark plugs today. I put NGK's in and the problem is still the same. I had it hooked to a code reader and it said I had a misfire in cylinder 2. I thought the plugs would have fixed it but I guess not.

I'm an Accent 2000 gs owner and since a few days i had this problem. It has a bad idle and looks like it will stall... need to give some gas to stay alive.
Bad acceleration too, it misses some gas. (puffing, rumbling, shaking a bit). After accel, it's ok until the next red light.
Now I can't even drive cause it's worse. (too difficult to accelerate). Is it a sensor?

I have a 97 Lumina sedan. When moderately accelerating between 50-60 on a slight incline, the car will sometimes start to "jolt" a little repeatedly. It continues to do it if I hold the pedal steady, but if the incline goes away or I press the gas pedal to accelerate harder the jolting will stop as abruptly as it started. The magic number seems to be around 55mph, never outside that range. I can reproduce it on certain interchange ramps or hills, but only in overdrive. Regular drive gear doesn't do it but the engine is at a much higher RPM. If I accelerate harder than I usually do it also doesn't seem to occur.
At first I thought it was just the same RPM loss issue at speed in a low cruising RPM, something that happens infrequently at idle. But now I'm worried the specificity might indicate a transmission problem. Car only has 87K miles on it for its age though.

I have a 2000 F-150 5.4 L. I was driving from home and seconds after the engine went into a rough idle that wouldn't let me accelerate. I scanned it and gave me multiple transmission trouble codes, about 15. I checked the wiring, the transmission fluid and it all looked good. So, what could be the problem?

Symptoms: (162K miles, last tune up about 70K miles ago) rough idle, and poor acceleration. Occasionally, the car really jerks while accelerating. I read about new plugs/wires, and something called seafoam. I think the highway patrol would pull me over as a gross polluter, but that too seems worth a try. Various sensors and hoses, I'm frankly overwhelmed. Where to start?
Something I learned today: My car was made in 10/95. Apparently, I can scan for trouble codes?!? How and where? Is it OBD I or II or something else? Dumb question: I can't even get the interior engine shroud off. I found three clamps, but it still hangs up near the top. What am I missing?

V-10 getting a weird hesitation on acceleration and rough, sporadic idle. Fuel filter is brand new, spark plugs only have 8000 miles on them. If im just cruising and give it just a little gas it gets real rough and wont smooth out unless I give it more gas. What else could it be? Coil packs?

I have a problem that has being going on with my 2000 toyota celica gt has been sputtering/jerking when going at a constant speed of about 60 mph. The problem is interment. I have changed everything from cam sensor when it came up on the scanner. Also changed the fuel filter and fuel pump. I changed the spark plugs. No luck the problem went away for about 2 weeks when I changed the fuel pump and filter but it came back. I got it scanned and the only code that comes up is P0420 which is a catalytic converter code. I have no clue where to go from here.

It's a 2004 V8 Touareg with 100k miles.
Getting horrible misfires and they're jumping around to different cylinders + other intermittent codes. The symptoms are ROUGH idle, and hesitating/shaking under acceleration.
The MIL has never come on in this car. But, it illuminates when you turn the key forward. (Almost like previous owner coded the light out?)
Replaced all 8 spark plugs, just ordered 8 new ignition coils. Hoping the misfires are the coil packs but obviously theres some other stuff going on here.
Pulled codes 2 weeks ago:
1) random/multiple misfire (P0300)
2) misfire cylinder 4 (P0304)
3) misfire cylinder 8 (P0308 )
4) warm up catalyst efficiency below threshold bank 2 (P0431)
5) secondary air injection system insufficient flow bank 1 (P0491)
6) secondary air injection system insufficient flow bank 2 (P0492)
7) 02 Sensor Circuit Slow Response Bank 2 Sensor 1 (P0153)
Pulled codes 1 week ago:
1) random/multiple misfire (P0300)
2) misfire cylinder 2 (P0302)
3) misfire cylinder 3 (P0303)
4) 02 Sensor Circuit Slow Response Bank 2 Sensor 1 (P0153)
Pulled codes tonight:
1) random/multiple misfire (P0300)
2) misfire cylinder 2 (P0302)
3) misfire cylinder 3 (P0303)
4) misfire cylinder 4 (P0304)
Cleared codes. Swapped ignition coils from 2 & 3 with 7 & 8. Drove around the block, then re-ran them:
1) random/multiple misfire (P0300)
2) misfire cylinder 4 (P0304)
3) misfire cylinder 5 (P0305)
4) misfire cylinder 6 (P0206)
5) misfire cylinder 7 (P0307)
6) misfire cylinder 8 (P0308 )
