Hi
I have a strange problem here whit a sieera cosworth 4x4. When you start the car it starts on 3 cylinders for afew seconds and then i runs very sweet and the car runs very good.
Now it is getting stranger! I have fitted an stage 3 kit but when you want to drive the car you can't get it above 3500rpm and it is like it's misfire but i is not misfire. When i put in the original injectors whit the stage 3 chip and 3 bar mapsensor the car is like a train!!!!!
So i've put a set of brand new 803 in it but the problem is still there. I've changed the fuelpump but i's the same. The car only runs whit the standard injectors. And it still starts on 3 cylinders for a few sec. Does anyone have an iday?
