1983 Z-28 with CFI. Never had a problem with the CFI, normally runs perfect. Plugs and wires were changed last summer, less than 1000 miles on them. My brother and I checked the CFI about a month ago and everything looked great.
Whats happening: After the cars warmed up, sits a few hours then runs again; Running around 1500 RPM, the RPMs start to fluctuate between 1400-1600. If I let off the gas, or give it gas, it stops fluctuating for a bit.
Anyone else ever experience this??
