My car is running like a bag of bolts

DezUk · 17 Jul 2006 at 16:37

Yesterday my car started to sound really bad and not drive properly. The tick over seems to be screwed up and at low revs its very jerky to drive. When pulling up to junctions it sometimes cuts out and I loose power steering, this has happened on a few corners but I have been ok. Its booked in for a service on Friday so I'm going to bear with it for now but was looking for any suggestions as to what it may be. The temp gauge is fine, the only difference is the car idles at about 500rpm when usually its just over 1000. My old man reckons it could be a dodgy injector but I'm open to suggestions.

Thanks

You could try reseting the ECU by disconnecting the battery. This will wipe the radio settings also though and immobiliser too?

Also check the vacuum pipe for the air intake is not disconnected as that can cause an erratic idle

The car is fitted with a custom Dastek Unichip which remaps all of original ECU settings, I will try the battery though.

Plug or Lead.

Ok at higher revs?

There's your problem. ;-)

Take it Dastek and get them to stick it on their machine?

Thanks for the tip about the pipes on the air intake checked under the bonnet after work there and 2 of them were hanging off. All back to normal now

Any idle problems on a Zetec engine are almost always due to a faulty or detatched vacuum pipe or the infamous T-piece fitment

Worth cleaning inside the MAF sensor with some carb and choke cleaner too.

Mondeo... There's is your problem.

/runs away.

Were are these air intake pipes dezuk? That sounds very like the problem on my 1.6 zetec in my escort, ive been advised to clean the idle control valve. I've already replaced the maf which sorted out the idle problem.

Well I have an adter market air induction kit so the pipe layout will be completely different. But look for any pipe wok around the air filter area maybe ?

How's it relevent to the thread though mate?

It will almost definitely be the idle control valve, a well known fault on the zetecs. Try cleaning it with some carb cleaner.

Princey · 17 Jul 2006 at 22:33

The fact that ford use the Zetec engine? :confused:

yes they do, they also use a TD, and loads of others :confused:

This is an st24, with the Duratec v6 though :confused:

silversurfer · 17 Jul 2006 at 22:37

Same as the noble isnt it (almost)

quackers · 17 Jul 2006 at 23:17

Probably because i mentioned my zetec engine and the idle control valve
