Ok so after messing with my blazer the other day and finally fixing the 4x4 (disconnected vacuum line) I might have caused the service engine soon light to come on. Does anyone know if taking off the cover to intake manifold could have had something to do with this. I only did that and I also reconnected the vacuum line. Could this be the answer to the light being on or is this something i should go get checked out?

 

I got a SES light when the hose clamp connecting the intake pipe to the MAF loosened up and eventually popped off. I'd check all the connections along the intake pipe, and also make sure the two sensors are plugged in and seated properly.


On an unrelated note, do you ever get anything installed at the Raleigh Circuit City recently?

 

The light is telling you something. Get it read and let us know what the code is.

 

thanks for your advice, and yes i got some speakers installed at circuit city recently, did you see me there? I swear i have seen your truck at cook-out on western before.

 

Haha yep I saw your truck at CCity. I work in car electronics, but the sales side. I get to hang out in the install bay when its slow And yes Im at cookout quite a bit, pretty much everyone I know lives between Gorman and Varisty.

Did you get the codes pulled yet?

 

oh cool, no i havnt gotten the codes yet, but my friend is borrowing a scan tool from the shop he works at, so ill probably find out monday.

 

I pluggedin ascan toolto the port and for some reason it wasnt working. It worked on my friends car, which isalso a 2000,and he says the tool is for all cars 1995 and up. Then a week later my check engine light just turns off and i havnt seen it come back on since (about3 days ago). Do i still need toget it looked at?

 

Check the CIG fuse.

If the light went off, then the fault may no longer be present, but I would still be curious as to what the code was.
