My engine is a 7.5 gas. I have not checked the cap and rotor, dont know what to look for if they are bad. I cleaned out the air idle control valve. The truck used to have a Jet computer chip. I removed the chip just to see if the truck would start better, it didnt make a difference. I will do the spark plug test tonight. The only thing I have replaced on the truck is a starter and battery, other than the fuel filter. I had a tuneup put on the truck in about the year 2002 which included the cap rotor plugs and I think the plug wires but I am not sure. Sincerely Jim Timboe
