90zxdriver Posted October 25, 2015 Report Share Posted October 25, 2015 About 6 months ago, while putting my foot into the gas pedal, as I merged onto the highway, my CEL light came on and threw a MAF code. I toof the MAF out, sprayed it with the cleaner, checked the connection and cleaned/greased my K&N filter. I then puled the negative battery cable for the night and the CEL went away. Well, today, same thing while getting on the highway and the same CEL code. I'll try cleaning it again but does this mean it's time of a new MAF or something else I can check?

SSenvy Posted October 25, 2015 Report Share Posted October 25, 2015 I had the same thing happen exactly. My truck seemed to run fine honestly, just an annoying check engine Light. I cleaned it Just like you did, it went away, but every 3-4 months it would come back. After about 2 years of the this back and forth, I replaced the MAF sensor and ive been check engine Light free for like 2 years now. They aren't cheap, I think it was like 250.00 with my discount from GM, but hey, atleast the CEL went away for good. It worked for me, Obviously its no garuntee it will fix yours, but it sure sounds like the fix. Good luck Quote Link to comment Share on other sites More sharing options...
90zxdriver Posted October 25, 2015 Author Report Share Posted October 25, 2015 The truck runs just as it did before the cel came on but I'm not somebody that can drive around with a cel on the dash. It will make me crazy. I'll try cleaning it again and see what happens. Quote Link to comment Share on other sites More sharing options...
90zxdriver Posted October 26, 2015 Author Report Share Posted October 26, 2015 Update: drove the truck tonight. Haven't touched the MAF yet but no cel? Quote Link to comment Share on other sites More sharing options...
levilz Posted October 26, 2015 Report Share Posted October 26, 2015 I get one every once in a while from my Granatelli MAF. Seems like it's more apt to do it when it's cooler out. I've flirted with the idea of switching back out to a stock one and selling the Granatelli, but just never seem to get around to it. Quote Link to comment Share on other sites More sharing options...
