Redfox340 Posted January 26, 2004 Report Posted January 26, 2004 Could be, but also double check your MAP sensor. A vacuum leak will cause the ECM to run a rich condition. - Erik Quote
90lum31v6euro Posted January 26, 2004 Report Posted January 26, 2004 my service engine soon light pops on and stays on when i push the car past 5200 on the tach. it just comes on and stays on solid, no blinking the car runs fine, no erratic idle or anything and when i shut the car off for about 5-10 seconds, it goes away is it anything i need to worry about?

Redfox340 Posted January 26, 2004 Report Posted January 26, 2004 is it anything i need to worry about? Yeah, even though the SES Light is not flashing, it's still an issue. You don't want it to flash, flashing indicates a severe problem detected by the ECM. You'll want to ground / scan the system ASAP: W-Body Performance - OBDI Diagnosis. Even the light goes away, the ECM still keeps a record of the faulty circuit. - Erik Quote
