E.F.I. idle help needed!
Guys I am at my wit's end here & could really use some help from those with experience.
I am working on a friend's fuelie Samurai, and have it running pretty darned good - it is very strong through it's entire rpm range, easily reaching 70+ mph. The problem is with the idle - after it gets to operating temperature, the idle will drop down to 'normal' for just a couple seconds, then it will go back up to 'cold idle' for a couple seconds, then back to warm idle, then back to cold idle - man, it's just like Clockwork, too. Something in the system is switching it back & forth. The ONLY thing I have discovered is that if I disconnect the vacuum line going to the MAP sensor & plug the intake off, it purrs like a kitten at warm idle. The rig does not give any trouble codes - only 1 2 = normal. A couple times, it went to normal warm idle after I had removed the diagnostic fuse??
ANY help on this would be GREATLY APPRECIATED!! [img]images/graemlins/crazy.gif[/img]
