Under full boost and wide open throttle I started getting a small misfire right at the top of the rev range. It's had a new coil, leads, 071c's, dizzy, cps and multiplugs cleaned out. Phase sensor looks brand new.

Took it out today and gave it a hoof, and it's like it's hitting boost cut. But much further down the rev range. Rev counter carries on to max though.

Also the ALS isn't working properly, when switched on it missfires under boost. (coincidence?) but this has been happening for quite some while before the above problem

And yes before you start I'm going to book it in at msd for a setup, but is there anything else I can do myself before I make that long drive?

T35 general stage 3 stuff with msd evolution chip, ALS and presumed standard internals. No idea of management... '91 4x4

Also Completely unrelated knocking coming from n/s/r but shakes the whole car. Deffinately rotational with vehicle speed. Wheel bearing good, wheel slightly buckled but balanced it up fine today, packed the rear cv's with tons of grease (were dry). Prop shaft appears ok without removal and doughnut tight, can't find any play in the rear shafts. No play in the wheel either.

Ideas please......?????

Proper pissed off as I only just put a new box and front prop on it (been off the road 6 weeks)

 

Owned the car for 12 weeks, have been able to use for 3 of them weeks :-(

Typical ford...
