Rough Engine Under 2500 RPM

[Limited '95]

My 95 Ex has been running rough under a slight load or cruising at under 2500 rpm. It seems the worst at 1500 to 2500 RPM. On moderate to hard acceleration or above 2500 rpm it performs fine. First noticed the problem about 30 minutes into a trip after the car sat for 10 days at the airport while I was away.

How old are the plugs and wires?

Have you cleaned the MAF?

I would give her a good Sea Foam treatment.

Good luck.....

i had a similar problem awhile ago, was a bad plug

Actually, the Sea Foam seemed to do the trick. I gave the TB a good cleaning as well and everything seems okay now. I had been cleaning the Throttle Body with the approved spray cleaner about every 5 to 8 k but had gotten away from that over the past couple of years because it seemed to be running so well. The longest it sat without driving it was the ten days at the airport over the last two weeks. Just long enough to let everything congeal.
