need some help with this one.

[ktg-dsm]

have a 91 GSX and it has a loobing idle but it is only when it it hot out now that it is cool out the car runs great. i am thinking MAF is bad or there is some sencer that reads air temp.

if by cold you mean the first few minutes the car warms up then my best suggestion is to check the adjustment of the throttle position sensor (TPS)
