Well I swapped a jdm h22 (year 94) into my 93 the car worked great for quite a while then an engine light started to come on when the car warmed up and the car would bog and lose most of the torque in lower rpm's, I think this is an O2 sensor but just though I'd get some other input.

Now the real problem, car has become like i said, hard to roll over when starting first I needed a new bat so I figured that was the problem replaced it with a 600 cold cranking amp. Still same problem, checked alternator by taking ground off bat, car did not shut off alternator good. A mechanic friend told me it was starter, replaced starter and no change.

good battery ,alternator ,starter why is the car hard to roll over? ](*,)

why don't you check the CEL code first instead of guessing what it is?

well I am 90% sure the light is because of an O2 sensor also the light came on before I had any issues with starting

*turn over

Also, pulling the positive battery cable off while the car is running is not a good idea because you can damage the alternator.

Pull the code and report back

yea I know, it can and will send an electrical spike through the system, if you know of another free way to check the alt let me know.

anywhay problem was starter, the one I replaced it with was just as bad, so I took apart my old starter and cleaned the **** off the comuntator. The car starts like new now
