Ok so today I decided it was time to figure out what was going on with this stumble. I started looking around at things and I found this plug on the air intake piping. . .it was maybe 1/2 a foot after the intake box. I unplugged it, took it for a spin and NO stumble! Thing ran like it just came off the lot. . .and its got 185,000 miles on it. . .What is this mysterious plug? MAF? Or is it another sensor? Also it didn't really feel like it was boosting too much but that may be because I'm so used to the stumble. Will someone please let me know. And also how to get down there to clean it (if its the MAF) or replace it.

Thanks,
Nathan

 

Anyone?

 

Pics would help if you can provide them. I'd like to know too...

 

ur maf sensor is bad. ecstuning.com should have them. if you want to try cleaning it, buy maf sensor cleaner at ur auto store. take apart the intake snorkel, then remove the (8mm hex?) bolts from the air box and loosen the philips screw on the throttle body end. spray the maf on both sides, let it dry, then put it all back together.

 

yep, def. bad maf sensor. if still bad after cleaning it will need to be replaced. is the CEL on?

 

Yeah for sure I will post some pictures of the process today. I'm thinking I will clean it today after court (some bull ticket). . .And to answer A4Speed's question, No, I do not have a CEL on. Is that bad? Or can that mean something?
