Hey Guys im usually not one to post in the tech section here, but i havent had much luck finding anything else. My daily is an 87 supra gte. bone stock. The problem at hand is for one the high idle.(In drive 12-1300 rpm warm) and when it gets to say 1650 rpm it surges,, backs down,, then surges again. and it will just keep doing that until i move from that rpm.. now i have checked codes, and the only thing i got was Code 14. Which is ignitor circuit, ignitor, or ecu as the trouble area.. I tried a new ignitor. No Dice. im going to possibly try to swap ecu's. but if all else fails,, how many other people have had a wiring problem like this,, and has it ever caused a surge like this? Now there is one more thing im kinda leaning on if the Ignitor is not the problem,, i suspect the Iac gasket is leaking/or the iac is now about as usefull as a sack of potatoes.... Any Prior experience with the issue at hand would be great.. Thanks..
