Went to put the car away before and started it up there was a clunk when i pressed the accelerator pedal, now when it starts it revs to about 4k!!! dont want to start it again like this incase it does any damage ,being stone cold.When you sit in the car the cable moves under the bonnet so im guessing it hasnt snapped? altho if you lift the pedal rather than push it in it comes out of the locating point in the bulkhead.Should it do this.?

Remove the cable from the arm on the throttle linkage (in the engine bay), and make sure the butterfly isn't jammed open. If it's all moving freely and returning to the closed position maybe the throttle position sensor has moved/jammed?

if the throttle is okay mate ie the cable and the butterfly you may have an air leak,

The car runs on enrichment at start up so an air leak will just cause it to rev, if every thing throttle related is fine have a look at the hoses

jaiscossie

Checked the throttle and the cable and all is ok there, its a jamsport inlet so a bit different to the normal one, has a cossie iscv which i checked but not that either.Any other ideas guys?

crazycage

if the throttle is closed and its still reving upto 4k then you have air leak it wont rev without air ! have a look at all the vac pipes that come off the inlet (boost gauge map sensor ect .

Sorry mate should have read your spec list, the above relates to MFI really, but should be essentially the same with efi. So do as crazycage says and have a good look for air leaks.

Rob,

Cheers buddy,would just a small airleak cause the engine with this setup to rev like like mad then?

crazycage

yes mate it would

jaiscossie

Checked for air leaks and found nothing, had all the inlet off and put back together with no improvement,any other ideas mate?

crazycage

un plug your idle speed control valve then start it mate.

jaiscossie

Tried this, took it out and cleaned it to. God damm the car lol

jaiscossie

Turned out to be the custom inlet had cracked underneath on the weld.

Did I hear roller-bearing ITB's?

jaiscossie

Was a one off Jamsport one,Am thinking of a different inlet but not sure what would go on with my setup?This it the inlet in the pic below

jaiscossie

Who does these mate?

project rs

it's an easy fix on your inlet, if i wasn't going away tonight i'd of sorted it for you for the postage each way but you might find a like minded person on here who'll do it for you gratis with some postage and give it a good check over at the same time

crazycage

if you want ill give it a good check over and repair it for free if you cover the postage.

jaiscossie

^^ Thanks guys thats really kind of you The car is back at my tuners at the moment so see what they say when its all apart as not seen under the inlet yet.Will let you know how it goes.

crazycage

tbh they will probably get it repaired for you then.

rs_traynor

my fiesta rs turbo done that.was reving really high and had no brakes.was the pipe from the servo fell off the inlet

jaiscossie

Getting the Jamsport inlet fixed and will sell it on am getting a new custom inlet made to a different design
