Check out ECM Medics. Im thinking of using them. I get a P0505 code after I cleaned the IAC Valve. Replaced the valve, no change. Able to set the idle and do the air re-learn, but if I let it idle in Park a while SES comes on. If I just don't let it idle in Park, SES doesn't come on (been off for about 3 weeks now). I think I may have shorted out the ECM slightly when I cleaned the valve, however, I have no driveability issues at all. Idle is smooth, no hesitation. the on thing it does do is, the idle "bounces up about 200 RPMs when letting off the gas, then it settles. The ECM is having some problem controlling the IAC Valve.
