A few days ago my SES Light came on, GAY (93 Firebird). Normally, I wouldnt think too much of it (drove 2 cars that had this light on for over 50k), but the car acts funny right before or when it comes on.
When it happens, i'll be cruising along nicely at 60 mph, right before it comes on, the RPMs will take a noticable hike and come right back down. I'd say about 300 RPMs. The light will stay on for about 10 seconds then go off. Over the course of about a 30 minute trip, it will do this about 4 times.
Yesterday, I was driving on an EXTREMELY Bumpy dirt road for about 5 or 6 miles going about 15 mph and the light was basically on for the entire time. As soon as I got off the bumpy road, it went off and did not come back for the remaining 5 minutes of my trip.
Besides the RPM fluctuation, the car idles fine, seems to run as strong as normal. The only thing that has changed in the last week is that I flush the radiator and added some A/C refrigerant. Car has fresh plugs, new K&N FIPK, high flo cat and exhaust was put on last year. I'd get it scanned, but someone told me they can only pull the code when the light is on in my car. One of the main reasons Im worried is cause I have to take this car on a 400 mile trip tomorrow, hopefully it will make it.
Any help is appreciated!
Thanks
