I have an 03 Aerbus with 8.3L workhorse engine. When we are cruising the engine runs fine but under load it misses and runs like ****. The engine has 24k miles on it so I'm not sure where to start. I am pulling the spark plugs now to check gap but looking for other ideas. We are trying to go on a trip this weekend so any help is greatly appreciated.
there is ZERO chance its plug gap and doubfull its plugs those are iridiuum plugs good for 100000 miles
coil packs and wires have been a problem at times on the 8.1
