low RPM miss
Hey guy's, mark here. Got a low RPM miss when I go up a grade on turnpike at highway speed. No check engine light but I need to get fixed. Engine is 3.1, 98 model. Could someone please help me as where I need to start. Does it sound like its tune-up time(plugs, wires, etc)

If it was an ignition miss, it would be throwing a P0301 or similar code. It sounds like dirty fuel injectors to me (possibly needing a valve job, also). I would start with a can of Seafoam fuel injector cleaner in a tank of gas, and "drive it like you stole it". Repeat as needed. Then start using top tier gas instead of the cheapest available, ESPECIALLY independent stations.

yes seafoam the 7 dollar can that will feel like a brand new car for a whole tank. i use to have a lumina with the same engine. if you cant remember the last time you had a tune up then do. also i belive techron does the same thing and its recomended by gm.
