help please throwing two codes after putting stockplenum on
hey all thanks for the advice in advanced. yesterday night i went to put my crawford v5 plenum on along with my kinetix test pipes. seems simple enough right...thats what i thought i had a massive vacum leak when i put the crawford on i now know why i had that and will install the plenum tomorrow during the day. my problem came when i put the stock plenum back on i sprung two check engine codes p0102 Maf or Vaf a circuit low input, and p0113 IAT sensor 1 circuit high input. i originally tried clearing the codes but that did not work as they came back almost immediately. i looked everything over and it seems to be all back in place nothing loose at all. so i have no idea where this problem is coming from any ideas will be helpful and greatly appreciated thank you

Check out the three reset procedures listed in this thread....

If you accidently touched the throttle plate or didn't disconnect the battery when working on the car, that might fix your problem.

TB reset is a ***** to get it going, but usually when your TB is off calibration your car will staul when warm after starting it. It will just fade out. If you disconnected the plugs on the back of the TB or pushed in the butterfly as mentioned above, thats your problem. Good luck with things, i had the same **** happen to me when i installed my spacer.

butterfly valve is pertaining to the open/close mechanism on your throttle body. Our throttle bodies are "drive bye wire" set ups, so if you take your finger and push that little flapper in with your finger your calibration is off.
The TB reset takes PRACTICE, dont give up because if you pushed in that valve or disconnected your throttle bodies plugs than your calibration is more than likely off. It would make it seem like a big *** vacuum leak that keeps killing your engine but its not.
