cj5 owners, or everyone... question
New to the forum but owned jeeps since 1947.
I currently have 3 (2002, 1994, and 1990).
The 1990 is giving me some problem. Sometimes (50-60% of the time) when I am driving under an acceleration or load situation it starts to backfire and sputter. If I floor the accelerator it will pick up speed just fine but if I am gentle on the throttle it coughs, spits, and backfires. It starts good (with a little grinding) and runs good at idle.
I checked the plugs, regapped them and drove about 500 miles. Plugs were power white. Additionally I am getting about 18 miles to the gallon mixed city/highway driving so I believe if anything I am running lean.
I replaced the fuel filter, plug wires, plugs, distributor cap, and rotor without fixing the problem.
So now I am looking for suggestions on how to proceed to alleviate the problem.
Your thoughts, ideas, or just comments would be appreciated.
OH. I also have a 1990 300ZX TT that has been highly modified that is why the ACar e-mail address.
Thanks
