Well I've changed my plugs, distributor cap and rotor, and tried my old wires (have magnecors), and my is still acting funny.

Same problem I've had... when cruising the car will kind of stutter just a tiny bit, no dramatic drop/rise in RPMs or anything, just hesitates. Sometimes it will do it from stop but mostly while cruising.

Occasionally, the check engine light flashes when this occurs, and in those cases the RPMs usually jump a bit (1000-1500) and then settle right back down, and the check engine light goes right back off.

A few months ago I had brought my car to Mitsu and they told me the check engine light codes were reading as a spark plug misfire, and that changing the plugs would fix the problem.

It hasn't. What should I try next? Is it possible I need a new distributor? Something worse?

Thanks in advance.
