For some strange reason my car is badly misfiring as it comes onto boost. It has got a Turbosystems chip with a hi/lo boost switch. High being about 15 and low being 7.
It only does it on high boost, sometimes just happening for a second and sometimes constanly.
I really need some advice on this one so any comments would be great.

Cheers Matt

 

sounds like fueling prob or timing would get air fuel gauge or set up

 

Booked in at Turbosystems next week so they should be able to sort it

 

had this with my car when running high boost.
changed the pligs for for standard ford ones (0c91s) and gaped them to 0.6mm. this cured all my problems,
worth a try as the plugs only cost £12 from ford.
