i pulled b2647 p0102 p0103 p0463

i know why on two of them. but what causes a p0102 p0103? i installed a ported tb and intake like a month ago and hadn't anything popped up. It was raining real bad... engine runs fine

[kyhunter89]

why would the maf read low and high? water in connectoins? need cleaned?

[kyhunter89]

i've checked the connections to the maf and cleaned it and it still does it. I take it, it needs replaced? somebody chime in here. I've cleared the codes three times now and the light doesn't come back on instantly, but its back on. if i need a new maf, iwhere'd be the best place to get one? autozone, gm or a certain aftermarket company? the truck feels like its shifting hard.

those two codes are high and low frequency errors, it's more than likely a bad maf.

the 463 is evap related and that is a very common problem, it can't be fixed, turn the code off.

[kyhunter89]

i thought it was the gas gauge?

[farmtruc]

oh ya, it is.

[kyhunter89]

so you think the maf is bad forsure? any maf better than stock?
