During the summer every once in a while when the car was cold it would feel like I lost a cylinder for a second. I'd be in 2nd getting out of the neighorhood accelerating and suddendly it would stop accelerating, then go back again. Now that it's gotten cold it's doing it worse. The problem is that I don't know what the engine's not getting, fuel, air, or spark. I'm planning on taking the dist. out and checking it, cleaning the TB, and putting a new fuel filter in to see if it does anything. Is there anything else I should look aat while I'm in there?

cap, rotor, wires, plugs, grounds.

are you getting an o2 code by any chance?

Does your car sound like a wrx..??
I know when I-4 motors run on 3 cylinders they sometimes sound like that
Maybe you have a misfire..

check what "2point2" said to check

1 is for the O2 sensor.

sounds like fuel cut mr2's and dsm's get (im sure other cars get them too).

A cut in the number 2 plug wire outer was causing all my problems. The car runs much smother with a new set of wires. I'll check that O[sub]2[/sub] sensor out too.

Yeah with a cylinder not firing it will throw a code for the O2 sensor.Reset the ECU and see if it comes back on.

The distrubitor doen't have many miles on it, so I didn't need to replace that. It is about time for plugs though...and an oil filter

Thanks Guys

Is your tach doing anything funny? One day my zc started missing randomly and it turned out that the crank sensor was on its way kaput.
