Well did some stuff to my truck today, installed the Magnacore spark plug wires, new NGK 55 plugs, a full service oil change.

But, then I bought a new MAF sensor. The last one I descreened, I was having problems with the trans slipping and I think it was finally going out. The past month or so its been running like crap, seems slower not just running right. Then I installed a new one instantly I noticed a difference, while ideling didnt make a pinging sound anymore. And at WOT it runs harder a lot harder and when it shifts its firmer and doenst fall on its face. I notice when I installed the corvette servo I could actually feel the servo ingauge and hold in the shift, maybe not enough line preasure. I thought it took longer to notice a differance in the computer but mine was instant.

But to all that ask the question to descreen the MAF leave it alone!

 

i been thinking of getting a new MAF too. i descreened mine a couple of years ago. truck runs fine, but i think it probably will run better if i get a new one.

where did you get yours? how much for a new stock MAF?

i need to replace my plugs too. i put in Bosch a while back. i am thinking of going to the tr-55's too

 

Well to tell you the truth, I called a dealership and they were 219 dollars. Went to my buddies shop he called one of his vendors I think was a dealership list was 209 his and my cost was 139.50 that just shows you how much markup they have on their stuff.

 

get them from gm parts direct. they have them for a good price.

 

thanks, that is what i was thinking of too.
