I've had my swap for about 2 years now. About 2 months ago I noticed the car stutters and then just goes back to normal when I'm traveling at a constant speed. Sometimes when I'm taking off it lags like crazy then launches after about 3-5 seconds. I've already changed my o2 sensor, injectors, cap & rotor, coil, temp sensor, ECU(from Kenji), fuel filter. I'm running out of ideas and getting discouraged. No mechanic can seem to figure out what's wrong. My friends suggested changing the TPS sensor, or PCV.

 

try rebuilding the distributer?

 

how about plugs and wires? dirty TB?

 

I already changed the plugs and wires. TB is ok. I just took out my voltage stabilizer, so far it seems to be running better. Never thought it would have that kind of effect. I'll try it out for the night and see what happens tommorow.


Thanks
