whats up everyone? i havent posted very much on this site, if any, so i'll do a quick intro of myself. I have a 95 GT thats pretty much stock except for a uncatted x-pipe, flowmaster from the cat back and a tremec 3550 tranny.
every since i installed the exhaust my car has been running very funky. idles rolls up and down between 500 and 1500 rpm's and is very rough.
lately i have been getting a rough vibration coming from the engine in my 95 GT around 1000 rpm's. it mainly seems to be happening when i jab in the clutch to stop, when the engine slows down to about 1k rpm's. but after i stop or once the engine settles to its normal idle (about 750 rpm's) or gets above 1200 rpm, its stops. anyone have any clue as to what to look for? i have cleaned the throttle body, maf, tps, and iac valve and that didnt help.
something else that i have encountered is that my car is running very rich, i partially expected this due to not having cats; but a friend has a 94 GT without cats and it doesnt smell like its running nearly as rich as mine. i changed the oxygen sensors in May or June of this year, so i do not think they are bad.
I have come across various articles on the web talking about people who seemed to think the 94/95 computers were the cause of the problem. i read another article that said the 94/95 had to meet emission requirements that made the cars run bad after modifications. it also talked of a few people who had swapped out a 94/95 computer for a fox body computer. does any have any knowledge of this? do you think this would help me any? thanks for the help.
