iv got an 89 escort and just fitted a 2.0l zvh turbo engine into it, but i have hit a problem, it is running the frst OFAB efi system, with every thing all plugged in it fires up, revs perfecly but dont idle, i have changed the iscv twice, tried another edis unit, and 2 different tps senors, and also tried a another ecu on it but still no difference.
i unplugged the tps and it idles lovely but dont rev, does anyone have any idea cheers

 

adjust the throttle stop on the throttle butterfly, or just bend the linkage a tad to raise the base revs.
