I'm working on fixing my idle search. All new vacuum lines, plugs and wires. Car starts and runs smooth for about 1-2minutes, then the idle dumps and starts hunting up and down. My ECU knob was turned full clockwise by the PO. I turned it back to the factory setting.
Stock 2.0L 1973 car with Pertronix. Where should I look next? |

not sure i can help as have a 1.8 L jet.
but have had an idle hunting issue and i think i cracked it....maybe. but perhaps not the same symptoms as yours. the cars are getting old, that maybe new issues arise in relation to materials etc. who knows. its fun sorting them out. see here what i found. don't read the whole thing. just go to my last post. http://www.914world.com/bbs2/index.php?showtopic=352145 hope you crack the problem.
