Hi,
When the vehicle is driven between 40 -60km it seems to pull back. the problem stops when I increase speed to 80- 100km. When I slow back to 40 -60km in starts to pull back again.
I have changed fuel filter and fuel pump thinking this was the cause, the problem still occurs.

Please advise what you think the problem may be.


Regards

HI there,

Is this the center point or multi point injection system?

Hi there,

Check for vacuum leaks around the center point injector and the manifold, they often leak at the rear near the fire wall, run some fuel system cleaner and check the air filter, check the base timing and a the two diagnostic tests with a scanner, check MAP sensor. start here.
