Hi
I am so stressed about this situation and need it resolved, I will try and keep this short as possible
Several months ago Engine light came on reading faulty maf sensor so bought a brand new sensor and put that on.
A few days later engine light back on which read a fault in the maf wiring loom, checked wires and ends were torn so my mechanic friend , Brian, cut ends off.
Car still ran rough with diagnostics and engine light reading maf wiring fault, so Brian said the colors of the wiring looked to be wrong color and in wrong sequence, so as he had some wiring in his garage he decided to have a play changing colors over trying to get it right but just guessing as we could not find color sequence anywhere. he has put connectors on temporarily where he cut the wires to attatch the donor wire to.
Then he decided to take the 6 prong maf sensor off my car and put a 4 prong maf sensor on, he connected 4 of the 6 wires from the maf wiring harness to the replacement 4 prong sensor and put 2 of the wires ( 1 at each end) into a loop saying these 2 were just open loop and not needed, he later cut off the 2 wires, 1 at each end, he said they served no purpose anyway as they are only open loop.
The problem with the maf wiring still persists, not as bad as previously as car not stalling any more but does refuse to accelerate if revved to hard , also if car has been off overnight for example and you press accelerator it tries to stall first time so you take foot off and press gas again and it revs fine.
these symptoms only occurred right after he cut the wires so they are definitely related to the maf wiring being cut.
It has probably been around 6 months now that I have been having these problems with the maf wiring , I did have it booked in with an auto electrician several months back but didn't end up going because my friend told me he knew how to fix it but he didn't and so I feel to awkward to go back to that garage where it was booked in at and I am stuck in same situation.
Anyway he is saying we should put the original 6 prong maf sensor back on and see if that sorts it ( even though only has 4 wires now as he has cut 2 end wires off, 1 at each end , he says that won't matter because they were open loop and not needed anyway)
Any ideas on this situation ?
please help, I am so stressed about it,
Many thanks
