My del sol with the y8 recently has started an idle problem and just progressively gotten worse. It started by every now and again would take a few tries to start it and now it always takes 2-5 tries to start it. When it does start it will idle from like 400 straight to like 2000 then back down then do that again a total of 3 times. It then idles around 1200 and once it warms up some it drops to like 400-600 somewhere in that range. And after about 30 seconds it just dies out. Also while driving when it isn't warmed up it will just die out once the RPMs get low. I push clutch in and it will die out when the RPMs get to around 400-600. Once it warms up it will idle down to 400 then come back up to 600 and idle there just fine but my lights are dimmed out some, I will give it a little gas it hesitates a little but does just fine.

I have replaced the plugs, wires, cap, rotor, and the IACV. I was looking into replacing the coolant temperature sensor, but I believe I have a single sensor system and just have the fan switch I have checked the wiring colors and that's what it is for.

Anyone have any help for me? Car is boosted also running a megasquirt ECU so it's not throwing a light because it never will, but not sure if it is OBDI or ODBII I would think OBDI so it can be tuned I could be wrong though. It is highly annoying having to turn my car off let the boost controller cycle while I hold my foot on the gas keeping it at an acceptable RPM.
