Thread: p0102 and weird noise on shut off

hey guys. obviously i have a P0102. i have all new sensors on the tb and im not sure what it is. the weird thing is that when i turn the car off there is a stange noise coming from right between the altenator and blower. it sounds like pressure is being released right after the motor shuts off. should i unplug the o2 sensor, then try it? or how about the maf?

unplug the maf sensor and see if it runs better or take a video of what it's doing.

Check the rubber T under the sc snout. Might be where the noise is coming from.
P0102 has nothing to do with the O2 sensor.
It's a MAF code. Check the connection on the maf, make sure there's no shorts, clean the maf.

check the wires at the plug for broken insulation or cracks, bad wires to the maf will toss the same code as a bad maf.

well i found a blown fuse to the maf. then i threw a o2 code. idk it tho. it said something about a heater low voltage i think. and the vaccum line is new that raps around the blower

If the fuse blows again you have bad wiring or a bad maf.

well im not throwing any codes but my idle is pretty bad. and when i turn the car off it sounds like pressure is being released above cyl 2 injector. its not the evap canister purge solenoid. i switched it from my other car. and i unplugged the map sensor and it didnt change. any ideas? im currently trying to upload a video to youtube..

its private

sorry. fixed it

Lol, looks to me like its your boost bypass making the noise.

haha. i know its ruff but ive had that for a couple years. i checked it already and its fine. is there anyway it could be coming from somewhere lower than the valve cover?

Wait... you unplugged the MAP... meaning you disconnected the electric? Or you disconnected the vacuum line? If you disconnected the vac line and nothing changed, then that would point to a vac leak earlier in that line.

Def vacuum leak. Check the brake booster line

i unplugged the electric connection. my boost gauge says 16 on the vac side. is that normal or high. from my memory it has always been there. so i dont think its a vac leak. it literally sounds like its coming from right between the alt and map...

why would you unplug it?
