22re Rough Idle

[96pearlrunner]

I'm sure this topic has been cover numerous times but I'm trying to chase the culprit. I've checked the TPS and followed the instructions on 4crawler and lcengineering's website. My TPS is within spec. I've checked for vacuum leak and none was found. My valve's been adjusted to 0.007" intake and 0.011" COLD like Marlin Crawler said. I came across the Cold Start Time Switch next to the Temp sensor and it reads 80.5 ohms cold and hot. It doesn't switch at all. Would this cause my engine to idle rough? I dont have a hard time starting the car when cold. Temp sensor is fine. Car drives fine. I've replaced the plugs. Another thing is when I'm trying to set ignition timing, the mark on the harmonic jumps all over the place and doesn't line up with the 5 Degree mark and when I remove the jumper connector it doesnt line up with the 12 degree mark. Please help me out. Idle is set to 750.

I have the same issue. Hard struggling starts when warm.

Sometimes the only way I can get it to start when warm is to have the throttle pre-revved before I turn the key. Had it refuse to even turn over last week without putting my foot down a bit. Otherwise it just clicked relay sounds by the passenger footwell when the key turned.

After some reading of my own, I was going to look into testing the temperature sensor first. Apparently it's a cheap part compared to the cold start injector.

I might consult my FSM to see if there is a test procedure.
