mk2 saxo vtr 1.6 8v latter engine in it on a 2001 plate
Right to the point....
on a 1/4 throttle the car jerks bad in every gear but not under 2000rpm...
it is on a serton part of the throttle and nowhere els.
If you use full throttle it is ok until i change gear at about 5500rpm then hesitates (not enough fuel) and goes again.
Car is not as fast as it was and as i said it jerks like no fuel/spark about 1/4 throttle but not after or before.
I have changed... temp sencer on top of engine, throttle sencer, lambda sencer, as always been running one as decated. cleaned up idle controle valve and thats working and idles fine. changed plugs and coil pack.
I checked new plugs and the tips are white hot. Car drives fine unless you hit that spot on the throttal but is at its worse between 2000 and 3000rpm and after that its not as bad.
Any ideas as really thinking of just taking it to scrap yard now.
Also was pluged in and only fault was missing cleared it took it out and re pluged it and no faults were found.
Really need help now. fuel pump primes fine and when cold and choke is on it drives perfect through hole rev range and through all the throttle. so 100% sure it is fuel.
Never cuts out on me as well
