injectors?? computer maybe.?

 

[john_hughes]

It runs fine at any speed. Cruises fine down the e-way. just a shake when taking off at 750 to 1100 rpm.

could be tranny??? Is it auto or manual? If auto, could be torque converter.

how are your axles ?

 

[john_hughes]

i dont beleive it is the converter i have had them go in previous vehicles. just rough right at first. could the cam sensor or another sensor do this.

 

[john_hughes]

it is in the engine for sure. something just doesnt want to let it go at first.

I'm almost out of Ideas shouldn't be the Turbo, so I'm really not sure. Really gonna have to think about that one!!

 

[MBRPCrazyford]

could be a sensor, but I wouldn't think that would make a difference whether your at a high or low RPM. Like you said, could be a cam sensor though.

John, did you find out anything?
