Engine Missing - ZR-1 Net Registry Forums

c4zr1 · 08-27-2010

I need a little help. I have a 92 with 17,200 miles on it. I know I do not drive it enough. It developed a miss and the engine service light is staying on. The secondaries are not coming on. I have changed out the plugs and fuel filter. Did not help. I am not getting any codes. The engine is idling right at 500rpm. I did do a reverse vacuum check and the vacuum does not hold constant, it leaks back down slow, but the vacuum pump does not stay on all of the time. It comes on about every 15 seconds and stays on for about 5 seconds. I did notice plug #1 and #8 was pretty black, but not wet with fuel.
I wish there was someone close that I could take it too, but Dallas is 6hrs away. Does anyone know of a good ZR-1 mechanic in Oklahoma City? I am only 4 hrs away from there.
Any help would be appreciated.
