RE: 1988 IROC-Z vert, 5.0 TPI, 5 speed
My ride sat up for 3.5 years after Hurricane Ivan with no starts at all. In March I had her flat bed towed to my mechanic. He drained & wiped the fuel tank, replaced the fuel pump, changed plugs (plug wires are +/- 10 years), ran ejector cleaner, cleaned air intake, new air filter. She has good acceleration and drives smooth while accelerating and at relatively high RPMs; however, at steady low RPMs she "bumps". It's like she is not firing all cylinders. Sorry if I am not being descriptive. Any sugestions you may have on what I need to have done would be much appreciated. | | |
