Hi all,

My wife has been complaining about her car'* engine racing at stop lights.

I bought it to work today, and It ran fine. But when I left, the Check engine light was on for 30 seconds or so.

Pulled a code 43 out of it.

I know GM sometime uses the same code to mean different things. Can anybody tell me what a code 43 means on a 94 bonnie NA?

Thx

43 knock sensor or electronic spark control circuit fault. Check the knock sensors and wiring.
