sounds like intake gaskets maybe to me. pretty common for them to fail. not the worst job to do really. at least theres no coolant to spill when you pull the intake off.

and you said it idles at 500 rpm? thats low. should be up around 700. in gear 650 ish at idle.

this one is up there but not real bad.

this one at idle looks ok to me really.

mine stock was leaning out to +8 or so wot in the higher rpm. stock tune kinda sucks. they run em lean for some reason.

just holding the rpm's in park is not the same as being under load driven, just noticed no mph showing.

over all thats not horrible. not great either tho.

you in NYC or one of the boroughs? im about 5 miles from the GWB down rt 80. if you want to come by i can run my hpt scanner on it and see a host of crap and know better whats up with it.

Have you tried cleaning the MAF sensor and another thought is testing the fuel pressure to make sure you don't have a clogged fuel filter or weak pump. These are some less than $5 options to start with since you rent the fuel pressure tester for free from most automotive shops.

yea that's the thing, at idle the numbers are good. once I start to give it gas the ltft start going up. I'm getting about 7 city and 11 highway. I'm in Queens about 5 minutes from jfk so we can definitely organize something just let me know when is good

I cleaned the maf when I changed my intake 2 months ago and I'll see about the pressure tester later today or tomorrow
