SOURCE: how to find the starter
This is what your starter will look like. It's usually on the passanger side engine. Follow your red battery cable to the relay, then follow it from there until it reaches the starter. Make sure you remove the red cable from your battery before working on it.

P1343. Misfire Cylinder 1 with Fuel Cut-off.
I would start looking at the air intake for leaks first. Make sure the intake boot isn't torn anywhere, inspect it throroughly around all grooves for cracks.
Also check the crankcase for excessive vacuum by removing the oil cap with it running, listen for idle speed change, and excessive vacuum entering with the cap off.
This would indicate the crankcase vent valve has failed under the intake.
It can be replaced without removing the intake, it's kind of a pain. You
will need the valve and the attaching hoses since they will need to be
broken to remove the valve, and they get brittle with age.
The
valve is located under the intake, slightly forward of the throttle
body. I wouldn't try do do it unless you're really mechanically
inclined, its kind of tough.
The part # for the valve is 11617501566.
Then the hose part #s are:
11611432559
11157532649
11617504535
11617504536
I hope helps.
