So I’m still getting a p0305 code after relplacing the entire ignition system plugs,wires,distributor,coil,etc.. I’m still getting a p0305 code but it only misfires at idle according to snap-on solus scan tool and kinda shakes a bit at 45-50mph. Also it seems like it isn’t shifting into od or tcc not locking up at 55-60 mph I can tap the brake and rpm’s don’t move and feels like it has plenty of acceleration at 60mph. Could this be related to p0305? I just did a transmission filter and fluid change but it wasn’t doing this after that. The truck has 203k on it.
