Clean the IACV. If that doesn't fix it, get the right ECU (you should get the ECU either way). If neither works, get a new IACV.


Isn't the P05 for the D15B8 (8 valve engine)? I don't think a Z6 will run so well on a P05 ECU.

Get the right ecu! I've had similar issues, it turned out to be the combination of a broken TPS and a vacuum leak.

pgpunkguy

if it's jumping to 3k, it sounds more like TPS than IACV...

well if the TPS is cracked, definitely fix that first.
