Chevrolet: 1992 Chevrolet Astro minivan, chevrolet astro, service engine soon light

Question
My minivan has new transmission seals, new water pump, new thermostat, new hoses, extensive brake work has been done, etc., Sometimes the engine will rev uncontrollably for no reason while I am driving and the "Service engine soon" light will come on. Help!

Answer
Hi B Woods, if the service engine light is comming on, theres something wrong with the emmission system. Have your van hooked up to a anlizer, this will tell you whats wrong, so you dont have to buy unnecessary parts. I hope this helps you, if you need more info just let me know. Regards, Keith.
