I've heard the crank sensor causing the engine to act funny. Hope this fixes the problem once and for all. Be sure to post your results.

OK I just don't know what to do.

Replaced the crank sensor still won't stay running.

Took off the ICM (that already tested good at autozone) and took it to Napa to have tested. Tested good again.

Have you tried unplugging your MAF to see if there'* any change? Another thing to check is the MAP, if that goes the engine will idle rough, not shift right, things like that.

I unplugged the MAF and it wouldn't start and run even with coaxing. Plugged it back in and it will start but same story won't stay running....


The car seemed to be locking/unlocking the torque converter the days leading up to it dying. Don't know if it was losing power or if it could be the MAP sensor messing up.....

I'm going to go pull a ICM at a junkyard in hopes that the one I have is weak but still tests good.

I have a really weak orange spark from all the leads.

I would say grab a MAP while your at the junk yard. Wont hurt to pull the MAF out and clean it with MAF cleaner.
