SOURCE: EGr Valve
The Dealership told me the 1996 models have an extended warranty up to 150,000 miles. It covers this problem.
SOURCE: I have reoccurring Fuel Injection problems with my 3.2 Acura TL
If the idle is rough but the engine otherwise seems somewhat normal, it could be an EGR valve stuck open.
This allows exhaust fumes into the intake path at a time the engine can't deal with it instead of allowing engine RPMs and a better air-fuel mix to be established before dumping the exhaust garbage into the engine.
Frankly, I have the EGR 'cheated' on our stuff; guess Gore will never be my buddy...
I would have it scanned free at one of the auto parts chain stores.
SOURCE: the tcs light and the check engine light came on
On permanently on mine ... I was told to ignore it since it was detecting carbon levels or something to that effect and since it was so old that the light would keep on coming back on unless I changed something else which would be very expensive ... so I chose to live with the light on. (I just hope nothing else happens which would have notified me that something was amiss ;^)
