Thanks for the feedback Turbz RB-25, Benzino33, RICCA, axe s, A31Drifter and TWINS33.
Im heaps green with skylines so its good to get some info from ppl with more experience. The mechanic that looked at my car reckoned it was the fpr because they usually hold pressure with the ignition off and mine doesn't.
So I'll try cleaning the AFM, check the connectors, check the IAC valve and the BOV. All this stuff is simple to do if I follow the Skyline manual right?
If I find its none of these then I might hit you up for that fpr axe s.
Cheers again for the help,
