Code 24, 32, 43 Get your chip checked here

[eagle mark]

A lot of guys can't fix a code 24, 32, 43 or have other driveability issues. This maybe a factory fault in your chip in the ECM.

I have a book here with GM Technical Severice Bullitens that will show if you have an old chip or if it was updated to the new "Fixed" version.

I need the year, engine size, VIN CODE (see below) ECM number and BCC of your chip. But to know for sure you need a scantool or chip reader to get the Prom ID number. Without this number it's a waste of time for me to look up. So if you have this information and want it checked post up!

Find your VIN below. Most common for this website EFI trucks would be
VIN "K" see below. I can look up your GM cars too!

Dammit, how come you didn't post this a couple weeks ago? Just kidding. Next time I throw a code, I will look up this thread.
