if any 1 has same fault wiggle the loom behind manifold and check for idle change or stall also check the wire loom for breaks or chafing right back to the bulk head this means striping the tape off all wires but it will save you money in the long run as iv spent loads on parts and labour to find out a £20 section of the loom would of fixed my problem and found that out myself lol
