Is there a way to remove the intake air screen?
Anyways, I did end up spraying MAF friendly throttle body cleaner in wide bursts through screen, while the car was running at about 2000rpm, to keep it from stumbling as the spray went in.
The Pk.Ave seems to have like this treatment.
Idles about 300rpm lower after a good highway boogie too.
I am going to remove the MAF soon. I can image the carbon gunk in there too!
