I have an 85 GL 4WD Wagon (not turbo). Had it for 11 years, and it's been an awesome car for a non-mechanic like me. Had the engine rebuilt about 9 years ago, have had some exhaust work done over the years, and have replaced a few parts (like the alternator) myself, but I haven't done a great job maintaining the car, so I'm lucky it's lasted me this long. About 220,000 miles.
I was going down the freeway the other day, going about 45 mph, accelerating in 4th gear, when the car just started sputtering, shaking, and chugging. I let off the gas a bit and it stopped. I was able to get home fine, but whenever I would give it too much gas it would start sputtering again.
It's been a little over a week since then, and I'm still having the same problem. Haven't done much freeway driving since then, but whenever I get up to about 40-45 mph and still accelerating at a decent rate, it starts chugging again. Accelerate more slowly and it's fine.
Any ideas? Like I said, I'm not a mechanic and I haven't maintained it very well, but I've poked around under the hood enough to know my way around.
I appreciate any insight you can give me. Thanks!
