Have a saff 4x4 '90.When its at running temp everythings mint,however starting from cold, car will occasionally rev by itself, it spikes straight to 2k sits there for a second, then drops back to idle.Also when driving car cold it hesitates, as if my discs are warped badly and catching(this has been checked and is not the case).
I have changed some parts, ie leads,d/cp,r/arm,coil.Have also eliminated TPS, all of this makes the car a whole lot better......but only when its warmed up. Any suggestions much appreciated, been driving me nuts for months now
