so my check engine light is on and i run the scan and it gave me a number of po300 witch is in the book as.. cylinder misfire detecter (random). so what could that be.
but did u put a new distributor on it plugs wires are good but a tune up includes the plugs and distributor to so id say try that and see if that helps
I wouldn't worry too much about it if the truck seems to run fine. Could be as simple as condensation on the plugs or a bad tank of gas. Reset the code and see if it comes back.
