My 95 z has a weird stutter/miss under about 2900 rpm under full throttle. as soon as it hits 2900 rpm or so everything seems normal. I checked the fuel pressure, its good, plugs and wires have less than 20,000 miles on em. it confuses me that it fixes itself anfter a certain rpm. Any help is GREATKY appreciated, Thanks.

 

A lot can happen to plugs and wires in 20K miles. Make sure none of your wires have been burned or rubbed through from the pulleys on the pass. side.

I replaced two bad wires and all my plugs and my low end stumble and running rich went away. The wires had about 15K miles on them and the plugs... about 4-5K.

 

i also say check the plugs. you could see if there is any sparks flying at night under the hood too. this would probally mean you burnt one of your wires. it possible that a plug could even have come a little loose.
