Sputtering at low rpm

[92redsho]

My 92 sho is sputtering at low rpm's and also backfires. when i get it to about 3000 and up it stops. what could be the problem?

and also the car doesn't sputter at all when in neutral or idle.

missing under load. try plugs/wires. also, try pulling the codes.

OK i checked the plug wires with a water spray bottle at night wile the car was runnign and saw 3 arcs in different spots from the wires. so i need new wires. and thanks for the reply.
