MAF engine code p0102 after vararam install
Just finished installing the vararam vr-b2 with the powerduct on my 03 z06 last night. Installation went well, with the exception of a few annoying firmest issues. Anyways, when finished, I started the car and it surged and studdered for a couple of seconds before the idle settled to normal. I drove the car as the instructions say for about 40 min. The engine light came on after 5 min of driving. Car ran fine, nothing I noticed. I ran the code last night and it was P0102 - "MAF,VAF low circuit input." What caused this?
1. I placed the MAF Sensor before the powerduct, between the throttle body and powerduct.
2. I checked for leaks and all seems well, nothing I can find...
3. I did have a little trouble inserting the MAF wire into the sensor. I'm almost sure it clicked in place.
Anyone else have this problem, and how can I fix it?
Should I move the MAF after the powerduct?
Any input would help! I'm nervous to drive the car with this code.
Thanks guys

Mine had a good bit of 'surging' when cruising at a constant speed after I installed the VR-B2. I didn't get the code you did though. Did some searching here and read that some guys installed a Haltech honeycomb screen to fix the surging issue. I got one and it helped a lot, runs much smoother now. Also some guys say the car requires a tune to run right with the VR, others recommended the screen.

I didn't install the power duct, just the VR and it didn't set any codes. It didn't run smoothly at a constant speed, it would want to surge a bit. The Haltech screen fixed this problem for me without a tune. I doubt that screen is causing much of a restriction, it's more to smooth out airflow before it hits the MAF. Not saying a tune isn't a good idea with this intake, I just didn't want to have it done yet.

P0102 is a MAF code not a Lean code.. The Haltech screen is a good thing to have but wouldnt trigger a P0102. Check the wires and pins on the connector to the maf. The wires will get brittle and can get damage if you moved them around. they sell pigtails to replace that section with the correct connector.
do you have any way to scan the vehicle? Check the wires to the MAF to see if they are damaged or broken inside. Clean the MAF with MAF cleaner and clear the codes.
FYI, this is how you want to keep the intake setup. And I also added a haltech Screen and it eliminated the "SURGE" i had as well at low speeds... It will not restrict the intake.. until the MAF is a restriction the screen will not rob any power, only make it more accurate and run better.

unplug the connector and check to make sure the pins are straight and then inspect for damage and reconnect.. Clear codes and see if it comes back.
Lean Codes are going to Be P0171 and P0174, so i know you have your connections tight if these are clear.

I had mine throwing codes after off and on for months once I put the halltech flowstraightener in never had another. They r paper thin so I cant see there being much restriction and the fact that the maf gets a better reading should make up for that and then some. For 50 bucks it worked great just drive it again without being annoyed by the light just with I didnt wait months to do it.
