all cylinder misfire??
hi im new, but i bought a 1996 ram 1500 with a 5.9. about four weeks ago. ran fine until a few days ago. check engine light came on and it ran and sounded like junk. at 55 mph in overdrive the engine is crusing right along at 1500 rpms and is shaking so bad that it causes the whole front end of the truck to hop around. this morning on the way to work i pulled over to look under the hood in the dark to see if i could see any of the plug wires arcing off eachother instead i saw the exhaust manifolds along with the brand new catalytic glowing. as i got home from work this evening i checked some of the spark plugs for their conditions. i found a majority of them to be alright but the rear plug on the passenger side was covered in oil. which no longer makes me think the cat is bad. any ideas?

Search for the spark plug wire routing TSB, sounds like that needs done too.

A majority of the time most people perform what they falsely believe is a tune up they're throwing away good parts "just because". Computer controls, hydraulic lifters, tighter tolerances, and electronic ignition have all made the tune up obsolete.
A tune-up usually refers to the routine servicing of the engine to meet the manufacturer's specifications. Tune-ups are needed periodically as according to the manufacturer's recommendations to ensure an automobile runs as expected. Modern vehicles now typically require only a few tune-ups over the course of an approximate 250,000-kilometre (160,000 mi) or a 10-year lifespan.
Tune-ups may include the following:
Tune-ups may include the following:
- Re-fastening of cylinder head bolts
- Adjustment of the carburetor idle speed and the air-fuel mixture
- Inspection and possible replacement of ignition system components like contact breaker points, distributor cap and distributor rotor
- Replacement of the air filter and other filters
- Inspection of emission controls
- Valvetrain adjustment
- Replacement of spark plugs.

The connotations of 'tune-up' though, are replacing standard wear parts. Cap, rotor, wires, plugs, PCV valve, fuel and air filters....... Terms evolve over time..... and a lot of what used to be 'standard', is now a distant memory, and considered 'archaic'.
When was the last time you hear someone say: "I need to reset my dwell."? (unless they were talking about their garden tractor.....)
