Hey everyone,
Just took my 2000 Gt on a good cruise for about 200 miles. Im about three blocks away from home just luggin in 3rd and out of no where the service engine soon light comes on !?!My friendhas this obdIIhandheld to indetify the problem. The check engine light is already on cause of the o/r Hand the obdII found that and cleared but wont find the service engine soonproblem!!! Anyone have any thoughts on why the service engine soon light came on? Checked everythingseems to look great and still runs great. Please help. Thanks.

 

Umm...once you clear the OBDII system whatever code(s) it has are gone unless it records the issue again.

Our cars only have one light. the CEL...(Check engine light) What's the Service Engine Soon light look like???

 

It says service engine soon towards the left side of the information cluster.

 

Okay, CEL = Service Engine Soon light...never bothered to see exactly what it says. Well if it flipped on and the car was lugging, how fast were you going? Could've been caused by a momentary loss of fuel pressure, stuck injector(s), misfire of the coil packs or the coil controller, could be a number of things.

 

It was probally 1800-2000 RPMs.

 

do u have mil's? if it came on because of your h pipe then i would say that is the problem again....

 

i've got this same problem. started out a different way though. i got mine back from the body shop and it was on. i went and changed my oil and ran a tank of premium through it and its still on. cars got 46,XXX miles on it. still runs fine and all that too. any ideas? maybe something that commonly happens around this milage.

 

hey amputist, id check the fuel filter.. i just passed 45k miles and it came on, changed the fuel filter (car was running fine) and it went away. could be a preemptive CEL trigger.

 

Take it to autozone and have them check it out. It`s free.

 

thanks. will do.
