SR20 red top poor idle and misfire

[Megin]

Had a similar problem with my blacktop. It probably is that you get a normal/high rev while idling, while the engine is cold, but it drops down after engine gets warmer and eventually the engine stalls when you depress the clutch, if you don't keep your foot on the gas pedal, a little. Also tries to buck at lower rpms if you take your foot of the clutch too early/fast

Changed the ignitor chip as mine was dead due to revered polarity on the battery (Worst mistake of my life, spent way too much trying to figure it out...)
Cleaning the MAF sorted it out (for now), but it still likes to dip down when I rev it up and get my foot off the pedal, still, it hasn't stalled.

I'd say check your MAF/TPS/IACV/Ignitor and Spark Plugs. Doesn't hurt to overdo when it comes to checking possible problems.

Also check if you are running rich.


Now to find my parasitic drain... -_-
