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.

01 Audi tt quattro starts to overheat while idling but coils down after driving at higher speed, is it a thermostat or the fast relay switch


overheats at idle only are typically the fan system. Cars use the fan to pull air across the radiator for cooling. Any speed over 10 mph there is more than enough natural wind to do this without a fan. If the problem immediately goes away when you start moving, it is probably a malfunction or issue with the fan. I have on more than 1 occaision had a customer tell me they had the fan replaced and car was still overheating, and it ended up thje fan was spinning backwards or not turning on because of a fuse or relay issue.

If it doesnt cool down fully once speed is above 20mph for more than 30 seconds, there may be other issues like plugged radiator or weak water pump impellars. water pump is a fan that moves water instead of the air. if the blades wear, they still kinda work, but at idle they work poorly because the broken blades only move a little air at low speed, rev the engine up, they spin faster and work better. If the fan is functioning OK (Turns on and off by itself) and car still runs warmer at idle than at rev, water pump may be worth investigation.

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.

How to fix this problem?


A big vacuum leak will do this it can be from a open PCV valve sticking open EGR valve to a sticking a IAC (idle air control valve) sticking open. You basically have something get stuck and closing.

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!

i would check the throttle butterfly for a carbon build up that may keep it from closing completely. have seen this cause stalling when returning to idle rpm. Best to try to remove and clean from both sides to get good results.this is just one of many possible problems. Hope it helps if so please let me know with a reply and good luck

mcdevito75 here, A vibration while idleing is not really normal, a rough idle could be many things, wrong octane gas, dirty gas filter, dirty smog controls. Have your local shop take a look for you.
