Car jerking / loss of power

[SHANES9818]

Hi there

I currently own a ford focus V Reg 2.0l

I’ve got a problem with it at the moment and wondered if any body could help me???

While driving at times I notice the car starts to hesitate or more like start jerking, even if I’m in fifth gear. If it’s not jerking I notice a loss in power for a second or two. I know it’s to do with a sensor but I don’t know which one and where to find it.

Can you advise me please?

Thanks

the way to find out if it is a sensor is to have the ecu codes read, but if the problem is intermittant there might not be any codes stored.

start checking exhaust and intake sensors first if you must dig in......sounds like that's where the issue will be.

double post....

Also i would check all your vacuums. Use a smoke machine or something. You could have a small vaccuum leak causing these isues.
