hesitates/jerking at low speeds
My 2.8 seems to hesitate/jerking at low speeds, especially around 30mph & gets worse as she warms up.
It started doing this after I replaced the Plugs, Leads, Cap & Rotor arm.
I'm not sure what's causing it, hoping you guys could help me out?
Cheers

Re: hesitates/jerking at low speeds
If you have kept the old stuff replace bit by bit as even new parts have faults . I would go with the leads first . Hope that helps

Re: hesitates/jerking at low speeds
Sounds like the timing is ever so slightly out - my first point of call would be to check the points gap and that the timing gear is set correctly
I had mine set to 6 degrees and it was OK, changed to 8 and made a world of difference!

Re: hesitates/jerking at low speeds
I'm with Jason on this. If the car was running perfectly well before, the chances are that there is an issue with something you've replaced.
The first things I would check is that you have put the leads back in the correct order and gapped the plugs correctly.

Re: hesitates/jerking at low speeds
If everything else has gone back on then it has to be points gap or sparks gap... I thinkAndrew 2.8i wrote:I'm with Jason on this. If the car was running perfectly well before, the chances are that there is an issue with something you've replaced.

Re: hesitates/jerking at low speeds
Have you had emissions checked? Too rich or too lean can cause those sort of symptomscapri28 wrote:I had the timing & fuel pressure checked last week, all, is ok...D366Y wrote:Sounds like the timing is ever so slightly out - my first point of call would be to check the points gap and that the timing gear is set correctly

Re: hesitates/jerking at low speeds
Could be coil ? If you have replaced all the old stuff and she’s still doing it you might have knock the timing out as peter has said .

Yes is was a faulty coil causing the jerking,Jasonmarie wrote:Could be coil ? If you have replaced all the old stuff and she’s still doing it you might have knock the timing out as peter has said .
With a New coil she’s now running spot on.
Thanks for all the help.
