    if the muffler is already cut out,now is the perfect time for a roadtest. Yes it will be noisy, but at least you will know.

    My mechanic tried that briefly, and he did not think there was a big improvement. But the muffler had to be replaced anyway.
    The next thing he will try is to take it to an automatic transmission specialist and check if the stator is the problem.
    how likely is this ? Im just asking because the bill is adding up the more stuff he has to try out.

    A seized stator is very rare. and the symptom is very sluggish acceleration, especially from a dead stop. Once cruising. the stator is usually stationary or close to it, so then you can't tell.
    IMO, I doubt you have a trans problem at all.
    IMO, you have a fueling issue.
    Yeah, it could be a bad coil, or possibly a valve timing issue, but I doubt it.
    Well I suppose if your timing chain jumped a tooth, between that and the retarded ignition that would cause, I suppose that could run the way that you describe.
    But to me it sounds like funky gas, or a bad tank vent, or vapor lock, a faulty power or pump circuit, or some kind of fueling issue.

    Hi AJ. I Think you are right that it could be fuel related. The ignition system is brand new, so is the fuel pump and filter. But something could have come loose from the gas tank and clogged the filter.
    Its a relief that a gearbox problem is unlikely

    Sunday afternoon, my car started running very similarly to what you’re describing. By Sunday night, the car was stalling when I would shift into reverse or drive and eventually I couldn’t even get the car to start. Fortunately it was already in the garage by this point.
    Anyway, after doing a number of checks that the others have mentioned here, it ended up being my “new” Jegs ignition box that I installed about 6-8 months ago.
    If you haven’t checked over your new ignition system, I wouldn’t rule it out just yet.

    Didn´t check that one yet... Is yours cracked so it has let in moisture and made it fail ?
    My car has always ben able to start up fine and run smooth in P - even now. So I don´t think it´s the ICU, but thanks for the tip :)

    Correct, the casing cracked and the module failed. Most of the modules currently on the market are prone to premature failure. They’ve left more than one person stranded, lol.

    Good luck.

    Well, let us know what the issue was when you sort it out. Curious to know.

    If no one has already suggested this , then I suggest it now, if yes then repeat what's already been said. If I were to make an uneducated guess I'd say your torque converter is in the process of locking up / binding up and will need replacing soon.

    Well, while we were a week on vacation (staycation in Denmark) my mechanic has done some testing. (Changing the carb and the rusty exhaust made no difference.)
    He is now 99% sure the problem is in the gearbox. :eek:
    It drives fine in 1 and 2, but when he tries in D and the gearbox shifts into high gear / lockup it loses power. He will take it to a AT specialist on Tuesday and get back to me after that.
    I will post here as soon as I know something - thanks for all the feedback :)
