I dont think the shunt wiring is wrong, i get no error for the transducer being electricly disconnected like "transducer open circuit" so that part of the circuit must be correct. that just leaves the 470 ohm resistor and the diode connected between wire 5 of the MAF signal to transducer return and i have confirmed the continuity on these wires. Looking at some of the other treads the consensus seems to be hollowing out the cat is not very detrimental. Also realize possibility i may have some air leak after the MAF sensor causing problems. Going to spend the weekend looking at this so will let you know how i get on. Cheers
