Ok, I'm back to the same problem. What occured was I changed the plugs and wires on my 97' and all the sudden it started missing. I decided to clean the battery terminals to see if that would help. It didn't, in fact it made it worse. When I but the terminals back on my Jeep wouldn't even idle correct and I had to limp it to a mechanic to see what was going on. The mechanic replaced the Flywheel Position Sensor and the Jeep idles fine. But, the first two times I tried to start it, it would only start if the Jeep was in nuetral. That problem went away and now it starts fine, but this engine miss is still here. I am at a complete loss as to why the engine is missing, but I've tried three different sets of wires and two different brands of plugs with no difference. What really throws me off is the fact that the miss seems to be completely random. It seems worse under light acceleraion, when I hit bumps, and when the engine is cold. When the engine is cold it seems to miss alot, almost to the point of stalling. After a while that evens out, but when I accelerate or hit a bump it misses. So, what I'm thinking is that there is either a fuel issue and for some reason it only occurs during these conditions, or there is a loose wire somewhere that moves or grounds out when the engine moves around alot. The fact that it is worse when the engine is cold makes me think there is a sensor that is malfunctioning, but I'm not getting any check engine lights, except for the flywheel position sensor which has been replaced. If anyone has any ideas what this could be, the help would be great. Thanks in advance.
