Question about 1996 Audi A4

1 Answer

Idle My car is idling heavy after it has been running for 10+ minutes, it seems like it might just stall out. I think it is the idle value, but I'm not sure where it is located to work on it. Any suggestions would be helpful.

Do you get a hissihg noise from the petrol cap? If so the problem could be a blocked tank pipe and/or filter.

Engine only runs at idle


If it's a Chrysler/Dodge product, disconnect the battery for about 10 minutes and re connect it. Try starting, be sure the battery has a FULL charge when you do.

Mitsubishi Lancer 2006 cooling / rough idle issue


Sensors do not always throw codes if they are close to normal parameters, needs to be checked with a scan tool and thermometer.

There is usually a high and a low speed fan relay, as well as a separate A/C fan relay (also high) Your High speed fan relay could be bad, or the fuse for it.

Engine idle surging usually means the coolant is boiling and there is no longer liquid in the throttlebody causing it to go to a high idle because it thinks the engine is cold. Warm coolant closes a valve lowering the idle on most Japanese makes of that year.

Also, sometimes Thermostats stick half open and do not allow enough flow. AND sometimes in neglected cooling systems Water pump Vains are eroded by electralosis causing low coolant flow as well. And a Clogged radiator can also cause this, as by the time the fans run on high it's to late.

BOUGHT BRAND NEW BATTERY NOW CAR CUTS OFF AND IDLES REALLY LOW


WHEN YOU DISCONNECT THE BATTERY THE ENGINE MANAGEMENT SYSTEMS PCM LOSES IT MEMORY INCLUDING ENGINE IDLING.THE COMPUTER WILL HAVE TO RELEARN THE OPERATING VALUES. IF CAR DOES A LOT OF STALLING AT STOP LIGHTS AND STOP SIGNS. GO BY FORD DEALERSHIP LET THEM REPROGRAM THE PCM.PROBABLY CHARGE YOU $35.00 DOLLARS. TO REPROGRAM PCM.

2001 Chrysler Concorde LXI randomly stalling while slowly dow to stop or turn. Will usually crank back. This car will sit and idle for ever, but when you drive it for 10-15 minutes and slow down to stop or...


One suggestion:
Speed sensor failure.

Info:
Some of the classic symptoms, stalling at dead stops. failure to auto lock doors. poor fuel economy. Failure to go to overdrive.


Recommendation:
Go to your local parts store and run the failure codes.

Shop notes:
Your ECU thinks that the engine is running with out moving, During slow down the engine steps down the idle to match ground speed and as a result the engine will not stall. At present it goes directly to idle and stalls due to drag on motor.
Hope this tip helps.

Runs rough and stalls out.


after installing the idle air control valve did you reset the computer or disconnect the battery for atleast 10 min to do a hard reset. If you have done this the computer still thinks you have a problem.

My 2002 Ford Taurus will shutter and die when running the air conditioner and sitting idle at a stop sign or stop light. When I turn on the air conditioner the rpms will fluctuate up high above 2 and then...


the idle air control valve is responsible for engine idle.
this is a common failure on ford's. but I don't think yours is bad because it does idle high befor it dies.
you stated you had codes p0171 and p0174 these are lean codes for bank one and two, you said you found a vacuum leak and repaired it, the vacuum leak was mostly likely the cause of the lean codes, however the pcm has calibrated the fueling stategy for this lean mixture, what you need to do is erase the KAM "keep alive memory" this is done by unhooking the negative battery cable for 60 seconds, this is the only way to erase the KAM the $6000.00 machine I use wont even do it.

once the KAM is clean the computer will go into a relearn state and all operating values will be adjusted for the vehicles current condition, during this relearn session the vehicle may have some driveability issues (low or high idle, stalling, poor fuel economy) the relearn should complete within 10 minutes of idling and then 10 minutes of driving.

good luck and keep me updated

1995 pontiac firebird formula v8 idle


The idle speed is not adjustable, it is computer (PCM) controlled, you can turn the screw for the hard stop, but the computer will just over ride that adjustment for the most part, what I think you may need to do is clean the throttle valve and the idle speed control air bypass valve, use carb spray, spray it in the intake with the engine running use the at least 1/2 the can, the engine will try to stall, keep it running, after you are done disconnect the battery for 10 minutes, reconnect and drive a few days so the computer (PCM) can relearn your driving habits and set the idle correctly based on your driving.
