Anyone know if there are after market intakes for a 2007 Vibe? I've been fighting a P0171 engine code for a while now. Replaced the MAF sensor twice (first one was suspect so they gave me a second one to try- no improvement thou) Changed out the pcv valve and lines, intake gasket and O2 sensor, all with no success. Just did the fuel pump, thought that was it because its had a slow-to-start ie seems like too much cranking before the engine fires. I cleared the code and drove it on the highway and then rechecked oxygen, evap and cat indicators only the Evap was still active. BUT when I restart the car the CEL comes on in a minute or two. last up on the possible repairs is a new intake. OEm factory intake is $512.45 at local GM dealer. Looking for after market or to see what crosses. Depending on who I check with, I'm told the 05-08 pontiac intakes are the same but do NOT cross to the Matrix even thou the engine is the same. Dorman lists a 615-560 for 03-06 Vibe, 07 and 08 Matrix.
open to hearing from the folks on this site as there seems to be some really knowledgeable people here. Thanks- Howard
