How many miles?
How long since the last plugs and wires were done? What kind were put in then--OEM quality and AC/Delco plugs?

Second level might be MAF sensor cleaning and IAC cleaning on the throttle body.

replaced plugs and wires tonight. problems seems to be gone. will know more on the drive to work in the morning. btw whats best way to clean the MAF and the air valve? thanks, joe
