Re: Stumped on 744T poor running 700 87

Well John, you had better get a re-wirin on the harness. First things first. Then check the distributor hall sensor for a signal. If those wires are damaged or the connector is broken it sure won't run very well.

BTW, my can ran fine before harness replacement and it runs fine afterwards. Also check the short connecting hoses for the turbo lines. They could be broken. Also the turbo inlet hose at the turbo inlet. Mine was cooked and mushy. If the all tells the ECU there is a certain amount of air comming in and the air is leaking out under boost, the car won't run too well. Check the Idle Air Bypass hoses for splits. Check the intake manifold gasket for breaks, you can see this if the basket is broken and puched out above or below the manifold. Don't forget to make sure all the large turbo clamps are tight too.

Good luck, w
