92 cutless 3.3L rough idle when driving

Does the "service engine" lite come on when the crank postion sensor is off a little? It was replaced recently and ran great for a while but now when the car is in gear and going down road, the car runs rough (The "service engine soon" lit is NOT on).

on a 92 no cel for the CPS.

Not sure what you mean by "no cel"? Also, could this be the problem (crank position sensor not quite aligned right?)

CEL, check engine lite. Get off the CPS, rough could be anykind of misfire, very hard to determine the cause of a vague description such as this.

So could be coil pack, spark plug wires, or clogged injectors?

If it is a misfire, yes.

How do I check the spark plug wires?
How do I check the coil packs using a voltmeter?



If it is a misfire, yes.

Go to autozone.com, repair guides, plenty of info there regarding checking the plug wire and coils.
