So I originally posted about my si hatch with a code 7 tps. I found that problem and fixed it. I now have better throttle response. But my problem is this, starts up and idles great when you drive it past 25 mph or go in 3rd and let off it dies? Or does the same thing if you try to give it gas to go up a hill. Usually starts back up after wards but does the same thing. Occasionally code 1 comes on witch from reading is my o2 sensor any ideas?

 

It kind of sounds more like a fuel problem. Try cheap first, get a new fuel filter. If the problem persists check your injectors, or cap and rotor

 

It has a new fuel filter and filter. Probably should have added that only thing I haven't replaced yet would be the cap and rotor. Could it be any other problem?

 

ignitor. try a known good dizzy, the going up a hill leads me towards the ignition system for sure

 

It has a brand new dizzy. The guy I bought it from put a new one in I'm starting to think that it is the cap and rotor now that every one I have talked to says that. And I tested. The spark to day 1-3 cylinders all did great 4 was a bit weak but I guess I over looked that one out saying to my self the other 3 will keep it going.

 

If you have a weak spark in the cylinder, then yes I would replace the cap and rotor

 

I replaced the cap and rotor. Still nothing. So I got in contact with the shop the guy whom I bought it from brought it to and they said it was electrical between the ignition ecu and fuel pump. Any ideas?
