I just brought home my "new" Jeep YJ. It's a 1995, 2.5L with 55k original miles on it. It was a sweetheart of a deal!
The guy I bought it from used it as a "summer toy" - and It has spent most of the last 14 or so years parked in a garage. I had a 90 mile highway drive to get it home this evening, and I noticed the following:
When starting from a dead stop, it acted like it wanted to miss when I was accelerating and the engine was under load. Warm engine or cold, it didn't matter. Idle was fine, but under a load it sputtered.
I also noticed that it was having a hard time holding 65mph in 5th gear going up slight inclines on the highway. It was hard to hear/feel with the wind noise - but I suspect it was sputtering then also.
Now... I'll admit straight-away that I'm new to Jeeps - and am also new to being my own mechanic (ex: I change my own brakes and oil, but have never replaced a clutch or transmission...). that being the case, if you toss out an acronym, please tell me what it means.
Back to the Jeep... I'm thinking that all the years just sitting have left a "varnish" in the fuel system... and that the problem is likely one (or more) of the following:
1. Old Gas
2. Lame fuel Filter
3. Partially plugged injectors
5. Bad plugs
6. Bad ignition wires
7. Something else entirely...
The gas thing is easy enough to take care of. What else would you folks suggest as far as a course of action to iron out the problem?
Are there any good fuel system cleaner additives or are they just a scam?
I'm all ears... Thanks!!
