low idle rpm on chevy suburban


Recommended Posts

MAF is what i was gonna recomend too...could just need cleaned, but you do need to be insanely carefull....i sale a ton of these MAF on this vehicle (and similar) and lots of o2's...could also be a loose vac line or something.

03 is throttle by wire.

I would dick around with the idle rpm.

Just put a small pulley on the alt
