cars been running fine for months its a 1.4 ford focus.
When i let off my accelerator best way to describe it is the car feel like its jolting backwards and forwards when de-accelerating in a low gear.
Like when im in slow moving traffic and rolling in first gear and i go to accelerate the car like jumps then if im to take my foot off the accelerator it jolts any solutions of fixing it or is it something im going to have live with?

at first i though it was sparks but they've been changed recently and HT leads im unsure of where to start looking?

Most likely to be the pcv valve tubing as collapsed.

Like the one in the pic.

Beanie439

okay thank you, are they hard to fit or pretty easy im new to this haha

Beanie439

jesus mine fucked only place i can pick mine up is online or from ford dealer and was hoping to get it sorted..

H3lsing

I went to ford it was about Ł15. If you look at teh front of your engine were the pipes are (manifold), well behind those you can see the tubing.

yeah, mines torn on the side... yeah mine cost me Ł21.99 from ford but there having to order it in

H3lsing

Yeah they have to order the real obscure stuff. Plenty info on installing this part if you search the ford focus section or google images.

yeah finally got it in.. too me a while having big hand wasnt something that made this easy for me... just had to clean the idle control valve as to get a better reach and more room i took it off and now im having a weird idle but ive read up and everyone saying to clean it so fingers crossed it that...

I would drive it around for a while so the ecu can retrain the air / fuel mixture itself. It should sort itself. If not then I would take a look at the iacv and maf sensor.

i was thinking that as i also though had i lost the gasket but looking at my mate his doesnt have one neither.. yeah im not planning to do it until Friday so might sort itself out by then

Beanie439

well cleaning the idle control valve made a little difference but car drives and feels better since clean and replacing the Crankcase breather pipe

I would give her a nice long drive on the motorway, it would help clear out any build up of carbon etc. An oil change would be very beneficial too.

yeah, since i put the pipe on ive done 90miles i got it on tuesday.. only had time to do the valve today ive been driving for around 1-2hours to clear it out and seems to be going good... yeah im taking it in for a service and MOT next week
