possible flowmaster exhaust problem? Maybe something else?

Thanks for the reply, do you have any advice on how to check on that problem. The issue is very sporadic. Im not sure if that makes a difference. Since replacing the cat it has been somewhat better. Its hard to determine b/c sometimes it accelerates just fine. Thanks

Without any codes, it would just be a guess... I would look at having the coil and ICM tested to make sure they are working properly. Most autoparts stores can do this at no charge. Have them test them 10+ times in rapid succession to really get them up to temp.

sorry about all the threads, i thought it would be a better way of finding a solution.

Definitely try Kyle's advice. He was spot on with my gf's Galant the other day. After that if its still an issue, as I said in your other thread, maybe see if the 02 sensor is gunked up. I had to do this on my Firebird, so I assume since that is a GM also, that the method would be the same. I haven't had to try this on my Blazer so IDK if it is infact the same process, but anyways- unscrew the sensor, take a clean paper towel or an old shirt thats clean (thats what I did) and just wipe everything down and get off as much dirt as possible. Re-install sensor and see if it helps any. Do this to the pre-cat's and main cat's 02 sensors. I noticed my Firebird ran smoother after I cleaned its sensor.
