I've had my 95 pickup (4 cylinder, 5 spd, no options) for about 2 weeks and have been doing some basic maintenance on it. I've changed the oil, tranny fluid, diff fluid, pcv valve, fuel filter, air filter, and breather. I was hoping doing those things would make it run a little better, but it hasn't helped. The truck has a rough idle and dies often when I come to a stop or even slow down. It seems like it's stalling more and more often. It also vibrates pretty bad at idle.

Anybody have any advice on things I can do to fix this?

The previous owner said he just recently changed the spark plugs, by the way.


Thanks for any help,
Richard
