I realized that diagnosing a car problem on the internet is tough, but here goes.
1999 ZX2 check engine light came on with no problem symptoms apparent. car started to intermittently fast idle (2500 RPM) local garage reset light and read codes - no error codes present car now occasionally stumbles at about 45 mph (no check engine light on now)any ideas?
Did they read the codes before they reset them?
Thanks for getting back to me on this one. They said no codes were present of any type. I'm not completely sure I believe them, but the engine light is not on at this time after a day of driving and the car does have a stumble.
If they disconnected the battery while checking stuff out, the computer may need to relearn how to operate the engine. A stumble or similar is not too unusual during this time. If it is still doing it in a few days, please disregard this response.

Oh, does the stumble occur in a predictable way? Maybe at a certain speed or near a shift?
Thanks
Oh, you said 45 mph, didn't you. Is it an automatic? You might be feeling
4th gear or torque converter lockup...Was it a Ford dealer shop you went to?
Thanks - trying to help PoD
Thanks for the feedback. I will keep my eyes on it.
My daughter is driving it, I will be taking it for a ride today. It was a local shop, not a dealer.
