Hi my cav z24 2.8L is running really rough, no power, and smells gassy...... i began to think it was clogged injecors but after running cleaner through them several times no difference.... whats my problem???

clogged catylic converter maybe?

Hmm yeah that sounds like a possible air-flow problem. Check the air filter, and exhaust set up to make sure nothings stopping it.

no cat on my car straight pipe to the muffler..... and the intake is aftermarket shouldnt be plugged anymore ideas??

I put a new filter on the car and the exhaust is fine..... I need suggestions!!! PlEASE!

do you have an aftermarket muffler? if you do, and its one of those pieces of shit off of ebay, that is your problem, if not, then im out of suggestions...

i would start with your MAP sensor

sounds like it is running rich
