1996 Chevrolet 1500 Pickup Question: check engine light on
The check engine light came on and took it to Autozone came back with two codes PO300 and P1406. So I replaced the spark plugs and wires. I also cleaned the distributor cap and replaced the rotor and the coils. I then cleaned the EGR value but did not clean the port and replaced it with the same gasket. How can I clean the port holes and with what. Had the codes earse took it for a drive and the light came back on. Check the codes again and they where the same ones. Don't know what to do next, please help. Sam - sam3
