Hey all, I'm still working on the problem. I did alot of boost leak checking, and found alot of leaks. Couple of broken welds (around the dodgy bov install from the previous owner), leaking clamps, vaccume lines with holes melted in them etc. So now when I do a boost leak test I can get it to hold pressure and it bleeds down very slowly. So I've made a huge improvement on that reguard. But the car runs exactly the same! No difference. Very frustrating. I've also done a "Clear self learn" through datascan. I took a datalog of the car idling and put the data into excel. Could I get people to look over it and see if they find anything abnormal? http://members.optusnet.com.au/marc_smith/datalog_3_1_2009.xls Thanks, Marc.
Yes Look at the Air Con Sw Column When your idle goes stupidly high, your aircon switch is activated, but your compressor does not activate, and your idle goes to 1300-1400 rpm Lines 612-929 to be precise.
Greg the air con relay activates in the same second it was requested by the ECU so I don't believe the datalog shows an abnormality there. What does concern me is the ECU does not make any effort whatsoever to control idle speed with the AAC, even when the A/C is switched on. However, these parameters do not link to a misfire issue.
basic but.... Its basic stuff i know but have you changed your spark plugs lately, a new set cured my misfire even though the plugs i inspected were seemingly ok.
