Question about 1994 Chevrolet K1500
I installed a new distributor in 1997 Chevy C1500 4.3L Vortec V6 (replaced the crappy plastic OEM version with new billet aluminum). Truck runs perfectly and idles better than ever. But... SES light comes on stating: "Manufacturuerd ignition control module or misfire". Do I have to reprogram the PCM and if so, how is this done?
Check the wire harness to the Ignition control module (ICM) or replace it. It cost around $40,00 from Auto Zone and it's common for the ICM to fail, or it may just be starting to fail and it's also know that the OEM distributor had a screen vent at the bottom of the distributor for ventilation to prevent condensation from forming in the distributor. Check to make sure your new distributor has a vent and that it's not plugged up with shipping plastic. Condensation may be forming causing the misfire in the distributor. Good luck and keep me posted.
