Ok heres the story, I bought this car a couple months ago and it seemed to run great but after awhile I realized that it has more power than what Im getting out of it, I then bought a cheap little chip off ebay jus to see the results and if it really worked, I put it in and it worked great I had a lot more power and torque through 1000-5500 rpm but it shudders and wont idle correctly so I took it out and now Im back to the old way with no power and what ever power I do have is cut out after 3000 rpm, and open throttle does absolutely nothing. any ideas on the problem?

Check for Codes and let us know what codes you get.

could be:
tps
o2 sensor/s
maf sensor
ect sensor
act sensor
bap sensor
vacuum leak/s
exhaust leak/s
stuck fuel injector/s
fouled plugs
bad plug wires
tfi
pip

i'm sure i'm leaving stuff out but you get the idea. this is why EFI systems have self tests. otherwise it would be a nightmare diagnosing things. keep us updated. we'll be here this weekend too

its the same process. the only difference is that the 94/95s use 3 digit codes. because of that it can be a little trickier reading them. i find its easiest to count the codes out loud and have someone else write them down. this way you don't have to take your eyes off of the CEL. after a couple of times you'll be a pro at it.
