Car: 1986 Porsche 944 Turbo
Problem: idles at 2400 RPMs
Well I spent most of the day today helping my dad put all the EFI stuff and intake back on the 944t.
It had a problem of idling at 2000-2400ish RPMs and so we got a new idle control valve (old one was broken) and another part and put them on. After all that we fired the car back up after a month or so and it idled at 1200 for about 30 seconds and then it doubled that.
This "idle control valve" has the hose (just installed a new ones today) from the wastegate connected to it, a hose from just before the turbo on the intake(vacuum side), and a hose after the turbo (pressure side) on the intake side connected to it. It also has a 2 wire connector attached to it.
This piece was physically broken into like 12 pieces so it got replaced. The car still idles really high.
One thing I noticed was that two of the connector seats were slightly cracked but not too bad. The car idled really smooth at 1200 at first for 30 seconds (cold weather idle plus it normally idles at 1000) and then it raised up to 2400!?!?
This is getting really frustrating.
Can anyone help me with this problem?
