    p0102 and p0103 with random loss of power

    1996 Audi a4 quattro 12v @240xxx miles

    Ive been having these two codes come up(p0102/p0103. It felt almost like the fuel pump is going out. I would drive regularly with codes cleared and at random the car will lose power at any given time for 2-8 seconds then switch on again like nothing happened. If I'm able to clear codes the car will run fine until that loss of power comes then CEL will appear and it will run like crap. It gets all jerky when i mess with the gas especially when I try to take off in first gear.
    Things ive done recently to the car in no specific order:
    Waterpump/ timing belt kit
    Pick n pull coil packs
    Pick n pull MAF
    Pick n pull fuel pump off of a 2001 b5
    Pick n pull camshaft sensor cause the connector snapped
    New fuel filter
    Cleaned out egr
    Cleaned out throttle body
    New spark plugs and wires properly gapped

    Only few things I could think of that are left are vacuum hoses ( should be a constant problem no matter if I had a CEL or not), fuel injectors ( should throw a misfire code?), or a cracked wire in the wire hsrness.

    I'm pretty stuck and I'm running out of time.. Its my only means on transportation and I'm scared that my random loss of power is gonna turn into no power and I'll be stuck on the side of the road!

    Check the terminals of MAF and it's connector and confirm they are making good contacts/ not broken.

    Sounds like a MAF wiring harness or a ground issue too..
