My 93 LX 2.3 runs pretty good, but when it warms up, the tach drops to about 1200rpms and stays there no matter how fast I'm going, and seems like the engine starts stumbling a bit, sorta shudders and then straightens up, off and on...don't know a lot about the 2.3 but mine doesn't have a distributor, just 2 coil packs, two plugs in each cylinder...any ideas?

Thats usually a sign the ignition modular is starting to go. But try cleaning your ground connections and see if it helps at all, and check the computer for codes
