Continual Lack Of Power Problem

that's rotten.how can they get it so wrong so often?

I think they may give you some bull reason why they dont have to give your money back.

I dont think the tech guys at the dealers are given the time they need to find/fix and then retest such problems.all about time and money.

I'd love to be a fly on the wall on tuesday.watch them squirm.good luck.you will need it.

I might have just solved the puzzle...

Spent all morning taking off the exhaust test driving (no difference with cat removed). Back to the drawing board...

Despite the bad advice from Ford that the throttle body was fine, I have returned to investigate it as it was my original theory (used a new method to establish the degree the butterfly opens with the pedal action, and now have determined that the butterfly does not operate properly at all times - seems when I tested it last time I was unlucky enough for it to work properly).

My electrical guru mate is coming around now and we will test some voltages etc from the motor that drives it. I will now return the injectors to standard spec and load the factory map and return to Ford demanding they test codes again (to ensure that the flash tune is taken out of the equation). My intention will to get some restitution from these wankers now that it seems I have to buy another throttle body.

Lesson here has been either be prepared to do your own diagnosis and fix the problems yourself, or sell your Ford before it is out of warranty.

This little exercise has all but convinced me to sell my ute and give up on the whole "fast car" routine. Will keep you informed on what happens.

Joel.

I think if you flash it back to stock it will erase any error codes.
