Hello there guys!
I got some problems whit my Cosworth that I can't sort out, so Iam hopeing that someone here can help me out! My problems is, that the car runs bad when Iam revving up the car to about 2000rpm, it drops down, and then revvs up again, over and over, even if i got the throttle even. Same thing happens at higer rpm too.
And this is when Iam standing still whit the car on idle. After many hours whitout finding out why this is happeing I tried to change the chip to an aftermarket tuned chip whit larger injectors etc, whitout oxygen sensor regulation in the chip. And the car runs great! So i tought it was the standard chip or the standard injectors that was causing the problem, so i orderd a new regulated chip whit the 803 injectors and was pretty sure that would help, but not. Same problem appeard whit the revvs. I tried to unplugg the oxygen sensor but no luck. Still the same! I feel that there is someting whit the emission stuff that are the problem, but i don't know what. So any tips would be lovely and be patient whit my english
