View 2 RepliesToyota - Pickup :: 1981 - Refuse To Idle / Only Sputters And Runs Rough
I have a 1981 Toyota pickup. when i start her. she starts fine, but sometimes she will idle fine, and then suddenly refuse to. it seems to be random. i can keep her running if i keep my foot on the gas just a little, to keep her rpm's up. but have to put her into N and keep my right foot on the gas and my left on the brake to stop her when she refuses to idle. when she does this on the freeway, it just sputters and runs rough, but as long as i have the gas on, she keeps going.
I don't know what it is that regulates the idle to keep her going when my foot isn't on the gas. also her serpentine belt is slipping. the one attached to the alternator, i can see her charge voltage dropping when she squeals her belt. that i know how to fix, but i'm wondering if it's that, that is the issue? i was told that, but i don't think her serpentine belt has anything to do with her idling. i was told how to raise her idle on the throttle cable and the Idle screw, but is there something else that regulates her idling?
Corolla / Matrix 2009-13 :: Toyota LE - Vibration / Rough Idle Low RPM
Basically when the car is in D and when i am stopped with the brakes pressed on at a stop sign or a red light, the car starts vibrating and i can see the the rpm going down and then receiving back up and going down again something when the car is in R. its a 2009 toyota corolla le 90k miles. when the headlights are on, the rpm stays high so the car does not vibrate or anything. other than this the car runs perfectly fine.
View 1 RepliesToyota - Rough - Exhaustsystems - Corolla :: 2005 - Shaking When Idle?
My exhaust system was replaced on my 2005 Corolla in August. After driving it for just a few days, there was a shaking when the car idled. The mechanic replaced two engine mounts and the idle was much worse! He said it was ok to drive, so I started on my planned trip across the country. In Denver I took it to a mechanic at the Toyota dealer and they adjusted the throttle. It was better for a while, maybe a week and 1,000 miles. Now it is worse than ever! Having gotten two totally different causes from mechanics, I am not sure what to do next.
Also just before the exhaust sytem went, I had the 60,000 mile service done and had the car totally checked out by both Toyota, and an independent mechanic who specilizes in Japanese cars. After a car wash in California, the maintence required light came on.
What is going on?
Toyota - Corolla :: 1993 - Rough Idle And Loping When Engine Warmed Up?
I have a 1993 Geo Prizm (Toyota Corolla) that idles roughly and lopes only when the engine is fully warmed up to operating temp. I changed the plugs, and wires are only 1 year old and seem to be in good shape. I suspected a vacuum leak, but have not been able to find one.
View 4 RepliesToyota - Suspension - Corolla :: 2007 - Rough Idle And Stall After Filling Gas Tank 100%
I fill my gas tank to 100% but I don't pump it again and overfill it like most people do after the pump stops. I then proceed to start the car. Initially it revs up and starts fine but when it revs back down to idle it does a rough idling (and sometimes it stalls). To get around the stall, I would restart and rev the engine to 3000 rpm for about 2 mins and it would be fine enough that I can drive away without it stalling but after a mile the rough idling stops and everything is back to normal. I replaced the PCV valve and it worked for about a year but it all came back again. I am stumped and every mechanic gives me a different reason and none of the reasons are even definite. It's one of those "lets try this and see what happens". One more thing, the car runs fine. It only happens when I pump more than 75% of the tank.
View 5 RepliesToyota - Corolla :: Sputtering / Rough Idle After EGR Vacuum Check Valve Replaced
I replaced my EGR valve vacuum check valve, but now started getting sputtering/rough idle. I'm pretty sure the direction of the vacuum check valve is correct, but I tried both ways to be sure and still got the sputtering at idle.
The old vacuum check valve didn't give me the sputter. I only replaced it because it was melted and I'm not sure it was working. I included a photo of it. It's orange and black.
Toyota - Corolla :: 1997 - Rough Idle / Stalling Noises While Stuck In Stop And Go Traffic
I have a 1997 Corolla with 150k miles.
I had my catalytic converter and flex pipe replaced this summer. Lately, my car has been idling rough. While stuck in some horrific stop and go traffic three weeks ago, it started to make noises as if it would stall out. It didn't, but it still sometimes makes those noises.
The car seems fine on the highway. No loss of power. I did think that the hood felt too warm on a recent trip, but the temperature gauge in the car showed no issue.
The car hesitated when I tried to start it last week, but normally starts fine. It was the first cold day of the year.
I saw some white smoke come out of the tailpipe last week. It only happened once. Coolant and oil levels are fine. The spark plugs look good.
The fill pipe has been leaking gas for several months. It leaks if the tank is more than half full and it drips a bit of gas when I fill up. Two mechanics have not been able to find the leak and have told me not to replace it until it is a problem, given the age of my car.
I took it to a mechanic today (not the one who replaced the cat). He told me that the rough idling is due to the new flex pipe being shorter than what was originally there. He assured me that the car is fine to drive long distances and that there was nothing wrong with it. There's no check engine light or anything on the dash to indicate a problem.
I should be relieved, but I'm not. I've lost confidence in my car. Can the stalling noises and rough idling be explained away by a changed exhaust system? Or are these signs of a problem about to happen?
Toyota - Corolla :: 2008 - Engine Runs But Car Does Not / Loud Grinding Noise
I was driving my car today, and I stopped at a stop sign. When I went to go, I pushed the gas, and my car revved up, moved forward, then all of a sudden it made a loud grinding noise (Like I was dragging metal sheets), and the gas stopped responding (but the engine was still running). The car still turns on, but whenever the gas is pushed, it doesn't go and makes that awful noise. What could be wrong?
View 2 RepliesPassat (B6) :: 2006 - Runs Rough Only At Idle
I'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 10 RepliesToyota - Corolla :: Choking Out When Accelerate Quickly
My 1996 Toyota Corolla has started sputtering (choking?) out when I accelerate quickly (like getting on the highway) or when I get up to about 70 mph. Is this a symptom of a clogged fuel filter or a bad fuel pump? If so, is there a way to tell which it is before taking it to the mechanic? Or could it be something else?
View 11 RepliesAstro - Chevrolet :: 1997 - Runs Rough At Idle
I'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.
Nissan - Maxima :: 1998 - Runs Rough Once It Warms Up - Doesn't Idle Well
My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.

View 1 RepliesToyota - Corolla :: 2010 LE - Random Rapid Gunfire Noise When Accelerate / Decelerate
I have had my Corolla LE since October 2011, there has been no maintenance issues whatsoever with it, and it has 65K miles on it. Up until September it was a solid, quiet ride, and with the passing two months, what started to be a quiet vibration, has grown louder and louder. At first I thought it was something inside one of my storage compartments rattling, and then I thought it was the blower, only noticing the sound when I turned on the heat. Now, it makes noise when I accelerate, decelerate, at a complete stop (with the car still on). I read another post about it might be the heat shield, and I was convinced previous to reading that that it was something exhaust-related. But, I'm not sure. This noise has gotten louder, isn't consistent with any function of the car, it appears to be random, but the noise is still the same, the quick "drr, drr, drr" noise, truly a rapid gunfire sound.
View 5 RepliesToyota - Corolla :: While Shifting Into 4th Gear And Accelerate The RPMs Drop - Power Loss
I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.
View 7 RepliesToyota - Corolla :: Drives Forward Just Fine But Will Not Reverse / Taking Forever To Accelerate
So, I don't know if any of these problems are related but a few months ago, I accidentally put diesel fuel in my car. We got it flushed out (used some fuel injector cleaner and filled the tank up to dilute what fuel was left after i siphoned it) and my car was doing fine. Then my car started running really shitty, just taking forever to accelerate, revving really hard when I gassed, but not going fast at all, so we changed the spark plugs, oil, and transmission fluid and now it drives forward just fine, but will not reverse. all it does is move forward a bit then stop. It will drive in neutral up to 20-25 mph. What might be wrong??
View 3 RepliesSierra :: 1996 SL V6 - Rough Idle After Tune Up / Skipping When Accelerate
1996 GMC Sierra SL V6. Owned since new. 100,000 miles, never tuned up. I decided to get a tune up in hopes of increasing mpg, and it was overdue really. New plugs, wires, cap, rotor. Got truck back and it runs rough, knocking, skipping, hesitating, bogging down when trying to accelerate, rough idle. Went from 15.5 mpg, down to about 14 mpg. They said they put in all AC Delco parts. Brought it back to them twice now and they cannot figure out the problem. It ran PERFECTLY before I send it in for a tune up. No problems whatsoever.
