Tacoma :: 2.7 EFI Engine Has High Idle Speed
Feb 22, 2011
1995 Tacoma with 2.7 EFI engine has high idle speed. When cranked cold idles at 800 rpm but as it warms up idle speed increases up around 1600 rpm. Does not idle down when clutch is fanned, have checked for vacuum leaks and have also checked most sensors. The exhaust manifold is cracked and I am not sure if this might be part of the problem. I am not convinced issue is not vacuum related but not sure of a definite way to resolve this question or issue.

I have a 99 tacoma with a 3.4 L automatic with 160,000 miles. For the past year my truck will idle rough and quit after revving high. After driving around for a few min its fine until I accelerate hard and get it up to about 4 to 5 thousand rpms. I recently changed the timing belt and accidentally got it about two teeth off. While it was like that, it didnt have much power and it was very loud, but it didnt have the problem. Once I fixed it and got it timed right it started having the problem again.

Had a first-time issue with my car today. Background, 2010 II bought in June, just short of 15K miles, never had any kind of mechanical issue.
While en route to work this morning, I was about halfway into my 15 minute drive to work, when I noticed my engine was idling very high, I would guess 2500 rpms. It started doing it while I was driving around 35 MPH, then continued doing it while I stopped at a traffic light, and continued when I continued driving to a speed around 50 MPH. The high idle while stopped was not transferred to the wheels, so it was not a safety issue as it would be in other cars.
When I got back up to 50, curious to try something, I hit the ECO mode button and the car returned to normal. I took ECO back off and the car was still fine. I had no further problems.
I would point out that this morning was about the coldest temp that the car has experienced. Outside temp ranged from 7 to 10 degrees.

1993 Geo Prizm, manual transmission: Intermittent failure to start over a two year period, gradually becoming more frequent. The engine turns over every time the key is turned to start the engine, i.e. the starter motor/battery/battery connections work flawlessly. Once started the engine runs flawlessly without misses or shut downs. The only possible problem may be the engine idle speed that seems at times to be too high even after the engine is warmed up. Without predictability, the engine may fail to start when the key is turned.
Remember the engine still turns over normally. It just does not fire up. Two options exist for my predicament. That which is resorted to the most because of the speed of recovery: step out of the vehicle and push start the car by popping the clutch. The other alternative which I have been forced to utilize before because of the physical impossibility of push starting (i.e. if I had been able to push, I would have popped the clutch to start) at the time has been to wait for a protracted period and re-attempt to key start the car. This has been successful a couple of times.

I have a 2011 Toyota tacoma with 35k miles. Yesterday while driving at about 70-75mph on the freeway with no warning the vehicle shut down and the engine light came on. It made a clunk about the the time it shut off, it wasn't very loud but I could feel it. I'n not sure if that noise was just the vehicle powering down or transmission kicking from the change in torque? I pulled off the freeway, there were no fluids leaking, serpentine belt was in place. The truck will turn over but not start. The check engine light flashes rapidly.

I bought my 3.6 in november with 2k miles on and now have 15k, in the last month or 2 I've noticed that at odd times it idles high. It normally idles at 500-600 id say and will randomly peak to 1000-1100. It wouldn't really bother me except it sounds like hell and I have to practically stand on the brakes for it not to jump forward. I've had 13k miles and 6 months of problem free driving

1998 saturn SL2 idle speed changes low, high, back to low. Some times the car dies, can happen any time a few times in traffic. Once the engines dies the idle stays low for 5 minutes, then the problem goes away for a while (a week). You never know when it will happen.

This is the code that comes up on my 2002 2.2 Cavalier. Camshaft sensor bank 1. After a lot of research I was led to believe it was most likely the upstream 02 sensor. Replaced it, engine light still on. Wipe codes, light goes off, turn off car, turn back on, light back on. What other possible problems could be causing the light to be on? It's been on the entire time I've had the car which is 3 years. I've had it e tested with the light on and it's passed with flying colors. It's up for an e test, actually I have 5 flipping days to figure this out, have it e tested and get a sticker for it.
I've been trying to figure it out for well over a month since I realized an e test was due and they've changed the way they do the tests now, they told me even tho the light most likely has nothing to do with the emissions they can't test it if the light is on period. I was told to start pulling fuses because it could be something as simple as a bad fuse. The car is in relatively good shape under the hood, no major problems and much of the car is still factory. No weird symptoms other then sometimes it will rev high at idle or low speed but as soon as I get to 4th gear it always balances out.

Camry 2000 CE 102,xxx miles. My car died in Jan 14, after have P0770 for while, only Reverse gear work. The mechanics said the tranny need to re-build. I had him bring the tranny to tranny shop to re-build ($1650), then the code still pop up. Brought it back, they said the ECU needs to be reset. I had the car next day then that code pop up again!
They replaced the Solenoid E. The code is still there. Brought the car back, they took the tranny to rebuild it again. Drive the car for a day, the darn code pop up again, now they blamed on the ECU. Ok my mechanic guy replaced it at my own cost for part ($150) but the code is still there. This time they blamed on the high idle rpm approx. 1600-1800. My mechanic tried to fix the high idle speed so the tranny stop blaming other causes. He cleaned IAC valve, replace O-rings (I don't remember the location of them) then he said whenever he inserted the new ones, they start to crack!

2004 Grand Cherokee. I was pulling a heavy trailer 1000 miles, and while coming down a mountain pass 50 miles from the end of the trip the check engine light came on. All other gauges (oil pressure, temperature, etc.) had not changed while climbing or descending and I was in low gear while descending to save the brakes. I drove the rest of the way to the destination without incident. I tried turning the Jeep off and restarting it several times to see if the check engine light would turn off and it stayed on. The next morning the light was off when I restarted it and has not come on again since. I hooked it up to a scan tool and received 2 codes: P0152 and P0132. 2 days later I noticed that it was revving high while idling and in Park. It would rev between 1500 and 2200 RPM while in Park, and at 900 RPM while in Drive. Also, while travelling at freeway speeds it seems like it's trying to downshift for no apparent reason. I hold the throttle still and have even tried cruise control and it intermittently increases engine speed, without changing ground speed. I assumed that I got the transmission too hot while climbing/descending and that the error codes listed above (related to O2 sensors) were associated with that, but now I'm wondering if something more has happened.

Bought my 2006, V6, about 2 months ago. This morning was the first really cold once since I bought the care. When I started it today, the idle speed was about 1200 RPM. It took a few minutes to warm up and then the idle speed dropped to normal. Quick question. Is this normal?

I have a 1998 blazer 4x4... I had a issues with the car before and I had to turn the idle screw up until I fixed my problem. I now fixed my problem and I need to know what my idle rpm should be at.
After I fixed the original problem after about a day of driving I had a P0507 Idle speed High/Low. I turned the set screw down and lowered my rpm. After about 5min of driving the code went away on its own.
About 1 week later I am now getting the P0507 again and now it has a buddy. P0446 Evap System.
Questions what would my idle rpm be? Can the high rpm cause the EVAP code as well.

I'm the loving owner of an amazing '02 RSX. She is just about to hit 100K, and has been completely trouble free. This past sunday, I started it up in the morning and immediately noticed a semi-harsh vibration, with high idle speed (1500ish, normal is 500). If I give it gas, the vibration and rumble noise goes away, but if it put it in reverse, it seems to get worse. After a few miles of driving, the idle speed returns to normal and seems to feel/sound fine. Also of note, if i hit a dip in the road, i get a vibration and engine sound that resembles that of a flat tire. I know this sounds random, but it's the best I can do at describing it. There are no check engine lights, temp is fine, and otherwise seems to be driving great. I initially thought bad spark plug or air filter, but have since thought of vacuum pressure or O2 sensor, maybe even an engine bolt break (from the sound it makes driving into a dip). Could this be as simple as getting a bad batch of gas?

1996 Ranger 2.3 140 CID XLT 126,000 Miles. When coming to a stoplight or stopping the engine idle is low and causing engine to almost die. Engine has been stuck at high idle a couple of times. It started with the engine idle slowly coming down and now it its too low. I suspect the Idle air control valve.

I've got an '05 Tacoma 4WD with 145,000 miles. Very recently, when taking right curves at moderate speed ( e.g. freeway cloverleaf onramps), I'll lose power at the apex of the curve. It comes back immediately when the I straighten out. No warning lights on panel. It feels like no gas since there's no difference when I press the accelerator pedal.

I was driving on a high speed highway (70 limit) doing 80 on cruise control and about 10 mins into my drive the car disengaged itself of the cruise control and the check engine came on for about 5 seconds while the car was forcefully slowing down by itself and then the check engine disappeared and I accelerated back to 80 and set it again for the rest of my hour drive. It wasn't just disengaging of cruise control it was like the engine shut off for a few seconds and then came back on.

Recently I've noticed that when I take my car up to highway speeds- 55 MPH or higher- the engine feels as though it hesitates- I don't actually slow down, but I have trouble accelerating beyond where it starts to lag. It's like an imaginary bump my car is going over where the engine isn't fully accelerating. Happens for a second, then goes away, but lately it's happening often- several times in a row- it just feels laggy, sometimes continuously, and i've got a bad feeling about it.Tires and brakes are completely new (Nov 2011, calipers, rotors, and pads replaced), oil level is checked weekly and has been fine lately. ~200k miles. It's a manual/ 4spd, I don't know if this is clutch/ transmission slippage, or if I have a piston misfiring, OR if maybe it's a fuel injection problem,,,,

I have a 2007 Tacoma 4 cylinder 5 speed. The clutch pedal started sticking about a month ago and has only happened a hand full of times. When the pedal is pushed to the floor it would stick, I thought it was hanging up on the floor mat at first but that was not the case. I went out to move the truck today and the pedal immediately stuck to the floor. Like usual I tapped the pedal kind of on the side to get it to release. the pedal then came back up. But now it wont push back in at all!!! There is only 1/2" of travel on the pedal and stops solid. It's like it is binding up on something. The spring seems to be in place the right way and nothing that I can see obviously wrong.
