i have a GSR swap in my 93 civic and it has run fine for a long time now it seems a little sluggish.. at anywhere from 2500-4000 it stumbles but clears up about 4000.and when i get into it hard it just seem like it has the pull it had before... i have changed the spark plugs... but it still ran the same... any help would be great

 

you change the wires or the distributor or the rotor button how about the timing belt

 

nope havent changed any of it... maybe it one of the wires off the o2 sensor? but i am not throwing a CEL..

 

is it missing

 

redline si-1 fuel system cleaner. clogged injectors bro. i had the same problem.

 

Hanover?? You're pretty close to me actually.

But go ahead and do a cap/rotor replacement. Your O2 sensor's fine if you don't have any codes being thrown.

Keep us updated.

P.S. If you'd like, feel free to PM D-Rob on here and bring the car up to Sound Innovations in Carlisle. Derek or I would be more than glad to help you out with anything.

 

well i took the o2 sensor out and it looked fine so i double checked the wiring.. one of the wires was only held in by a little bit so i fixed that problem and it doesn't seem to be doing it now (yet) but i'll keep everyone poseted. thanks for the help
