hi newbie here. i was wondering if any one can help me with my problem. i have a 93 z28.it is missing under acc.or a load around 2200 rpms.if you let off some it goes a way.or if you give it more it also goes away. can anyone help please. thanks mike

 

hmm...... low RPM miss..................

how many miles?
how old are the plugs/wires?

 

My vote is for plugs and wires

 

I would also say plugs and wires. My friend with a 94 z had the exact same problem and after replacing the plugs and wires it was fixed.

 

plugs and wires are new.so is the fuel filter.

 

sorry miles are 111,000.
