I have a 94 z28 which runs fine when it is cold and warming up. After I
drive it about 1/2 and hour or so it starts to miss at 2000 rpms. If you
depress the throttle at 2000 rpms 55 mph it jumps and misses. If you floor
it it seems to run okay and take off.
The garage replaced the EGR valve and $220 later it does the exact same
Anyone have the same problem or could give me a guess?
In a situation like that, there are many possibilities. It's only obvious a
garage will work on the maybes, but meanwhile it's costing you money & not
them. I have the same problem with my Corvette. I'm having it looked at from
my GM mechanic beginning of next week. I'll post up the results.
