Hi folks,

Anyone on here fancy trying to help me out. I've just bought a sapphire cosworth from my mate who has owned it for 10 years. The last few months it hasn't quite ran great and he has lost interest in the car so I'm just trying to get the old girl running so I can drive to MSD for live mapping.

It's a 2wd saph but with a 4x4 engine fitted. Still has l6 ecu and loom but I noticed it had a pf09 tps so I ordered a pf01 and fitted it as well as 071 ford spark plugs gapped to 0.6mm and tbh it's worse.

When I got it she idled at 500 rpm and nothing's changed apart from now it struggles to rev and misfires terribly. Won't start unless using heavy throttle. The AFR gauge is erratic and jumps from 10 to as high as 17 in an instant. Garage stinks of petrol. I've tried to check for air leaks and have put new ptfe tape on the plastic vacuum fittings on the inlet as well as the brown air temp sensor. I've riggled the cps plug with no difference and did the same with the dizzy plug I even put wd40 in the connections.

Also when it idles at 500rpm and I disconnect the idle control valve it makes it worse I think, sometimes cutting out.

I dunno if I need to setup the tps or not, tbh I've did research on this and still don't understand how to adjust the damn thing.

Sorry for the big speel but can any cossie gurus please fire some suggestions to me and I'll investigate from there.

(4x4 lump, fully rebuilt 7:5:1 comp, standard coil, blue ht's, t3 turbo, dark greens on stage 3 chip just incase it helps)

Thanks Adam
