OBD1 cars don't have crank sensors. You just have the cam sensor in the dizzy. You could try swapping out the dizzy since they are everywhere and really cheap. Just to try it.

So that 0101 is the crank angle sensor in the distributer?

I would try to clean the AAC, if that is what you meant with ACC and then fake a high AAC value to the ECU with warmed engine. Idle should rise.

However, that won't work on a JWT I suppose?

If you get a knock code, then probably your ignition is more advanced then JWT says or your gas can hold?

I'm not sure what you mean with ACC doesn't hold pressure or how you measured that. But I also don't have much faith in a fuel pressure issue, however, it is not impossible, would tell me you hit 2 problems (almost) instantaneous.

Maybe your AAC is stuck wide open.

LOL. Thanks I will try the ICV soon. In AAC I meant key on no start.

And I just happen to have one. This is the first time I ever got a code from the ECU ever.
