I have a 93 chev s-10 truck with the 2.8 V6, with 248,000 miles. Problem is when getting in high rpm's in low gears right before the shift truck starts missing, I sometime have to shortshift to avoid the misfire.I have changed distributer cap,rotor, plugs wires,spark plugs,and fuel filter and still same problem.
