idle problems please help willing to pay or trade

[mitsubishigirlfriend]

I've recently had a local shop build a dsm for me. It came back with a 50trim then I sent it to get a 6262. it had different fuel system and differnet intake/exhaust manifold from then til now. Its always had idle issues since i've gotten it back.

have you done a proper BLT?
idle surge is caused by these problems.

1) vacuum leaks
2)FIAV (fast idle air valve)
3)BISS (base idle set screw)
4)IAC or ISC (same thing. idle air control)
5)coolant temp sensor
6) iac ecu drivers
7)dirty throttle body

heres a link to help you out:

have you done a proper BLT? <do you mean belt? or is that an acronym for a sensor I am not familiar with?

Replaced
1)IAC
2)ECU
3)throttle boddy is a new s90 (had this problem before)
4)CTS
5)02 Sensor

Today I'm replacing
Power steering pump bc I remember seeing on the dyno the belt looking like it almost stopped and they used a 1g pump they had.

Also the TPS


The way our cars are it doesn't hurt to just start replacing shit.

have you tried the coolant temp sesor? thats the only thing i can think of except for a boost leak test

any way you can put up a log of the idle?
