First thing in the morning, going to check PCV, damn thing cracked in pieces at the lightest touch
Imediatly threw check engine light,
Got lucky to find a overpriced at shelf at stealership, bought it and replaced it.
Also replaced licence plate bulbs with LED
Ok now check engine was gone but still idle high,
Started to investigate vacum leaks, have a air sucking/blowing sound coming from the rear of TB intake area, found That it raised the idle rpm when i sprayed start gas in That area,
Replaced brake booster vacum hose and some others That looked alittle cracked at the ends,
The vacum line going behind engine towards torpedo wall from one top to the another and have a t piece going to the resonator box was cracked at the ends going to the engine,
tried to tape them up with electro tape, but still no dice
Its still raises the idle rpm when i sårt start gas in the rear top end of the intake, behind TB,,, aaaaahhh!!!!
How sensitive is this vacum system???
This now starts to irritate the H out of me, cause idle at ~1000ish rpm, makes it shift hard from P>N>D, and fuel consumption is out of wack.
Any or all ideas apriciated, i really need this fixed, its my DD,,,
