I was driving home from work, and right as I was nearing my house my check engine light came on. Lately, the last 3-4 tanks of gas have gotten REALLY bad gas milage.. im talking like 10-14mpg. I dont know if the weather has anything to do with it, but we are getting snow alot. I have changed the oil every 3 thousand miles, and also clean the MAF sensor regularly. Do you think the bad gas milage is the cause of the check engine light? Maybe its running to rich/lean or something. What do you think I should do from here?

Sorry for the double post... but I went to autozone, and about after 5 min of convincing the guy it was ob2, and that the port was underneath the glove box, we got it scanned. It came up with one code: P1407 He said it was a manufacter code, so he couldnt tell me what it meant. Anyone know? EDIT- After running a search I came up with this P1407: EGR NO FLOW DETECTED What does this mean, and should I still drive the car until it gets fixed?

P1407 -- a regular culprit in this code is a faulty DPFE sensor, and/or a faulty EGR vacuum regulator...it's possible the EGR valve is damaged, but I'd suspect the other two components first.

You Need To Pull Off The Throttle Body ....

Check The Pathway After The Egr On The Lower Intake Manifold Chances Are It Is All Clogged Up. Wire Brush And Some Sea Foam Should Do.

if the vacuum line from the EGR to the vacuum regulator solenoid in front of the passenger side valve cover has broken or is damaged, it could also throw that code, as that happened to me....its the green hard vacuum line, at least on my '97 it is
