I have the same problem... was told it is a vacuum leak, possible around the PVC valve.
old fuel filter
Being a GM product I would suspect the fuel pump is bad.
It could be multiple problems. check your coolant level, it could also be your Lower intake gasket or even a head gasket.
water in the fuel can cause an idling motor to sputter and/or die.
One blown bulb or fuse could cause this problem.
yes.
A clogged muffler can.
Yes, when idling and driving.
It is located on the passenger side close to the firewall and it is down low
my 1990 300zx is idling rough what could cause this?
The ABS Disable light may come on for a number of reasons. I started having issues after driving on wet roads. The source of the problem with my Rendezvous was related to corrosion of connectors, primarily at the two wire bundle connections under the front wheel wells - which cost over $700 to replace/repair. Repair shop told me that it's a common problem with Rendezvous and is primarily due to a poor design. Other issues I've had with my car have all been electrical - Thanks Buick! BBaaspencer here..mine was caused by a bad hub bearing and a bad abs wiring harness.
If a car shakes and loses power when idling it can be the spark plug. If a spark plug is fouling, it can cause power losses.
