Cool engine problem

if i start my cold engine, it runs only on seven cylinders. i think so, because it is not a round running. whats the reason?

"a round running".......What's this mean....."smooth" maybe??:confused:

Engine heat might cause a circuit to complete itself.

Check wiring for a fuel injector or coilpack.

You need to figure out which cylinder isn't firing... this can be done with a thermal heat gun aimed at the exhaust manifold or by unplugging a fuel injector and starting the car... listen for change in idle speed and sound.

Check the wiring harness at the rear on the engine at the left side. See if it's frayed.

Also pull off the coil covers to see if there is any moisture.
