Ok, found out the lead to the airbox sensor was disconnected. I pluged it back in, disconnected battery for about 20 min and reconnected that. No more codes. (did that last night). Today noticed it started a little easier, but don't think problem is fixed. So here is what I think I am going to do. Gonna start with plugs (NGK), wires (MSD), I think I will changes the Coils as well (MSD), however should I change the ignition module as well?? Will that make a difference?? Also gonna change the fuel filter. Future mods will include K&N System, Exhaust and Chip. By making changes to the ignition system will this require any changes with the chip right away or is this something I can do before I switch the chip??
One other question ... with the airbox sensor, when going to a K&N system, what will happen with this sensor?
