My car is running like crap and I 'm getting misfire codes.
it doesn't do it all the time but seems to be worst when I just try to drive a constant speed. I've resealed my collectors on the dynatechs and it didn't help any. I have new plugs and wires, maybe I should change those out again?? It's coming from cylinders 1 and 7.
any ideas???

 

help!!!

 

See if you got a light show under the hood at night around the plg wires. If not wet down the wires w/water & then check.
