I have a 92 se. When engine warms up it has a rough idle.Also there is hesitation until 3000rpms.is reached.I just performed vts sprocket repair{not new},new gas filter,spark plugs,stillen cone filter,timing is dead on,ran injector cleaner through three times.From what I have been reading it may be the o2 sensor.Any input would be appreciated.

 

I have a very similar probably. at idle is it so rough that it dies sometimes? I have reason to beleive it may be my alternator because when I have everything on. stereo, heater fan, lights, fogs.. the stereo flashes and wont play. also I have experienced a dead battery twice this week. Im gonna have it tested.

it could also be the 02 sensor, clogged injector, bad injector, there are lots of others. Do a search I posted about this a couple times and people gave me some good advice. It could be a vacuum problem too.
