94 Z28 running rough, any help?

[1st TA]

My boys 94 Z is stumbling all over itself on accel. Have not checked for codes and no lights showing on dash for check engine. Car has 150000 on the clock. He has owned the car since 141000. Do not know when the plugs, wires, and or opti have been replaced in a while. The car did it once before and than quit. Started doing it again today. Any ideas or help would be great. Thanks

Sounds like its a missfire. Just do a tune up, could also be a clogged fuel filter, but doubt it!

I had him change the fuel filter the last time it did this. Which was not to long ago. Ya it is mis firing, but like i said it did this once before than quit, now its doing it again. Thanks for the reply.

Possibly a spark plug wire arching.

Well the intermittent problem is gone again. What would come and go this way? Any ideas?
