Re: Backfire from throttle body...

I stated above you had to break shit to do it, and in that case, the engine ain't gonna run. It would also be rather obvious.

The Gen 1 shaft is longer than the screws... I dare you to do it.

This is one of those cases where you all will just have to take my word... Having owned my 92 for 13 years, I have seen (and done) pretty much all there is with that damned ignition system. I swear, I have a masters in Opti... ugh. And then there are always the "I have seen it done" tales, and Brian - I bet that opti was seriously messed up to force it on wrong.

The gen 2 opti uses a keyed drive, and it's REAL easy to get wrong - I did it! And it took me a week of tinkering to confirm I did it. the opti looked flush, but it sure wasn't... the chassis on the opti was off just enough - about a business card thick worth of off.

But that meant the key drive - more accurately, a pin drive - was not in the right hole.

There are three holes in the engine side drive shaft.

There are three machined out voids on the same shaft end.

The pin will fit into only 1 hole - the correct one. It will not fit in the other two holes. But the damned thing WILL fit in the God forsaken voids. Five shots at getting wrong, one shot at getting it right. I know my historic odds.

I will have to post pics.
