Alright! so i got my lowers painted and some new sweet wheels and the SWEET! suspension installed, and lots of crap fixed. oh and i bought an FMIC from the classifieds in flat black with flat black piping like 5min ago, a heat shield 5 min ago! and like here's the issue:

My car has a CEL that wont go away related to the EVAP system at first says N80 incorrect flow, so i check the valve it's ok, and well i got a new one and it works, but now i get o2 sensor S2 high resistance i think p0441 code or something! my car is acting funny, at a stop light the VAC will fluctuate between 10HG and like 8HG 11HG and so on, while the A/C is running and like 15HG 16HG and 14HG when the A/C is off! Car gets Despicable gas mileage, and i started my car today cold start it idles fine for 1-2 seconds then boom goes into cold start mode and revs to 1200 RPM's! i'm getting so tired of this car i wanna kick it! lol! And everything rattles! God forbid u push the gas from a dead stop the interior sounds like Motzart out of tune! FIX IT! TY!

well you answered your own question for part - it sounds like you have a vac leak somewhere, and that + a possible bad o2 could very well screw your gas milage.

rattles = loose stuff... if it moves and shouldnt tighten/duct tape it. if it doesnt move and should - loosen/wd40 (kidding about the duct tape lol)

check to make sure there arent any hoses loose or that fell off, and tighten your gas cap and see if that helps

Hey Kirk, I thought you had an Akipol side mount.

check your check valves. those little inline half grey, half black orb lookin suckers. i got the same codes as you before i switched them out. on top they loked fine, and then i spun them around and it looked like they were melted.

Did you finish checking the vacuum lines? Idle is still weird?

Funny. I don't have anything related to the airbox in my car (and no air box) and I get no codes. Your ECu must not like you.

^^my car hates me with a passion, 5k in maintenance in less than a year is disgraceful! the only reason i keep it is because it looks good even broken down lol! idle is better, hopefully saturday i can have my uncle take a look and do a smoke test and change out the 02 sensor!
