Sounds to me like you have a leak somewhere in the intake system. The idle fluctuation sounds like a vacuum leak- and of course, when the turbo spools up, you have positive pressure replacing vacuum. Look for a loose hose clamp or a torn hose, etc. etc. By the sounds of it, you shouldn't have any trouble finding the leak.

I have a 2001 Toyota Corolla. The revs fluctuate whilst idling.


could be a bad TPS or stuck, bad, dirty idle air control solenoid (IAC). check fuel pressure and check for vacuum leaks after the air flow sensor. more info is needed because what you describe could be many different things or a combo of different things

Idle fluctuates on 1995 f250, sometimes dies, sometimes revs, no apparent vaccum issues, IAC with scan tool reads low voltage issue. Could this be vaccum, charging system, faulty computer? Problem is...


Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

Engine fluctuating and cutting out all the time when slowing down to stop cos the revs drop too low


Hi.

If engine revolutions are going up and down even when you are driving, then you have a problem with the EGR valve.

If problem is only when engine is idle, most common fault is the IAC (idle air control) valve, which regulates air when engine is idle. If IAC is OK, check air intake and the sensors installed in the air intake (MAF and IAT). The sensors detect the amount and temperature of air coming into the intake and determine the right amount of air to be mixed with fuel and injected.

There are more problems that even if less frequently can cause rough idle. A good thing to do would DBII DTC scan can be done for free at the nearest Autozone.

Regards.

You need to have OBII scan performed. The fluctuating idle sinus like a MAF sensor, Temp & fan are separate issues. Get scan done, that should identify exact issues.

Should the oil pressure gauge fluctuate with speed


The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!
