Hello I hope this the right section for this post. The engine is a 4e-fte. The problem, Car starts and idles at 2k without going near the accelerator the engine starts to warm up and the 'hunts' dropping to 1.8k revs and back to 2k revs. I have searched and found a hand full of topics for high idle and not much luck on finding one with similar enough symptoms as mine. The things I have tryed. Changed the distributor and cap with arm, new plugs leads and king lead. Changed the two wire coolant sensor for new. Changed the vacuum pipe and MAP sensor. Adjusted the throttle cable and stop. Cleaned the throttle body housing and Barometric spring, replaced the O ring seal on the idle screw, used home made new gaskets, leak checked with brake cleaner spray. Disconnected the IACV, Checked operation with a power probe. Changed the valve on the rocker box and tried running with it unplugged. Removed the thermostat, checked for air locks. I have ordered up a head set and I am thinking of replacing the inlet manifold gasket/ to head and the injector rail with new seals. If anyone has some info on this problem please reply.
