    Any recommendations for fuel injection and ignition troubleshooting for a 1983 308GTSI/QV. Seattle area, preferably north.

    Cold starts fine, but I don’t get a fast idle. After a few minutes the idle will increase. There is also slight ‘tic’. No noticeable change in rpm, but just seems like a plug is not firing sometimes.

    Runs strong and even without any stumble, but even when cruising there is still a ‘tic’.

    When hot and at idle will run rough and am even getting what seems to be a full bank intermittently cutting out. Rev the engine and all returns to ‘normal’ (‘tic’ still there).

    Injectors are essentially new. Battery is new.

    Air pump is disconnected (no belt) as is egr valve. Been that way since before I bought it 8 yes ago.

    I had similar symptoms, mine traced to a cracked hose in the hidey hole of the trunk and a crank sensor going out, I replaced two crank sensors for good measure and has been fine since

    Well .................... somehow I had the impression that you were disinclined to work on these 'older' cars, otherwise I never would have started this thread. I'll contact you.

    I was just about to post - please contact Mark G.
    He will take care of that issue.

    Glad to see Mark already chimed in.
