Well last night I was driving home and the check engine light popped on as soon as I left the parking lot. The car wasn't bogging down or acting strange in any way, so I drove it the rest of the way home. After about 7 or 8 minutes it turned off.

I checked the codes this morning and I'm getting a 43. "Low voltage at electronic spark timing circuit".

How can I fix this? I tried searching, but it told me 43 was below the minimum word size.

Any help appreciated!

 

That's odd. The EST connector is on the passenger side fender...I believe it's a single-wire tan connector. Ensure that it's hooked up.. That basically just gives the computer the power to electronically advance your timing. Without that, you have zero advance...so you're always running base timing, besides the little bit of mechanical advance in the distributor itself.

There's an EST module in there that I assume is somewhere near that connector, but I've never seen it or heard much of it so I can't give ya any more information on that..
