friesianlover87 Posted May 31, 2008 Report Share Posted May 31, 2008 Hey everyone, having some issues with my 93' STS. Whenever I drive for about 10 minutes and get up to 90km the "Service Engine Soon" light comes on, now I've checked for codes but theres nothing other than A048-history which has always been on because I dont have working air conditioning, but I'm sure thats not why the service engine soon light is coming up. I just had an oil change done, I'm starting to think maybe they tampered with my car some how...?? Any idea's why it needs "servicing" ? Heeellpp. Link to comment Share on other sites More sharing options...
