You knw what... the intake was Prolly an Ebay intake...
It doesn't have any Brand Markings on it... ( I bought it off someone ) I didn't knw that some Ebay intakes were a Rip off... When did that Become a Fact?

As for the Throttle Body.. Can We even Replace that? Has Anyone even Tried?

Fyi.. I still have not Replaced the O-ring from the MAF sensor.. Took it to get a CEL Reading.. Told me i have Not enough Fuel being Injected, Misfire of Bank 2, Faulty o2 Sensor.. and another one but i cant remember.. So what i'll prolly do is go back to Stock and see what that will do.

you should of tried to fix your maf issue, tbh i dont even remember there being an o-ring around my maf when i replaced it, those codes indicate there is a lean condition and that small leak will cause that to happen, like i said i have a cai, ive even ran it w/o a filter (w/o my knowledge) and everything was fine, fix whats broken 1st before changing things around

Updating on the intake issue....

installed the O-ring Back onto the Sensor today... Reset the ECU.... CEL came back on for me once again.. I just came back from a Computer Reading , Messages from Reading state.

Message 1: MAF sensor inconsistent with TP sensor.

Message 2: Fuel system too lean at off idle - right bank

Message 3: Fuel system too lean at idle - right bank


Someone Suggested to clean the Throttle body and check for Vaccum leaks... What you guys think?

can u take a pic of your engine bay? ive never heard of any of these problems, i can think of bad maf, maf harness is pulled off the top of my head but thats it, if you put the stock cleaner assey back in and everything is ok then either maf sensor harness was pulled or the intake was causing stupid problems. try resetting your ecu one more time, keep the neg cable off for like 10min

My MAF does have an o-ring. I even used some plumbers silicone grease around it so as to keep from tearing it, but very sparingly and as a precaution. It's very thin and delicate.

I had those same last two codes when I too was having trouble w/the MAF sensor. The first one I am not familiar with.

It seems that hose (red plastic) from the intake to the factory PCV system hose (black) is a potential problem as well. Why is it there? Doesn't the factory hose clip onto the nipple on your intake?

the location for your maf is actually in a better spot than my name brand one, the only thing i dont get is what rich is askin and thats the pcv tube not connected to the intake, thats not gonna be a problem as far as a leak because i had those stupid mini filters on both ends and didnt get a cel from it.

I honestly dont have a clue what your cars deal is, when i first got my intake put on a cel also came on, i drove it for a while and it eventually turned off but i didnt reset my ecu, try to tough out the cel for about a 100 miles or so and see what happens.
