Hello,

you're saying:
"if i put my foot down would go lovely until 4 grand in 4th gear then it would jus splkutter n kangaroo after it done it once it would do it the whole time i went to put my foot over half way down it would build up a bit then soon as it started to move it would kangaroo n splutter "

and this

"forgot to say if i turned it off and started again it wouldnt do it its only every now and again and doesnt always do it but like i said when it starts it wil do it the whole time until the car is switched off cheers"

this sounds like the ecu is cutting out the engine, becouse of to much boost. I also had this problem with one of my fiesta turbo's (broken boost hose).

I could be because of:

- actuator not working because of a disconnected/broken boost hose
- actuator not working because of wear
- actuator set to high (higher boost, above 0.65 bar), but no chip installed


Just connect a boost gauge and see how much pressure it gives.
To messure this, put it in 4th gear at 1500rpm and floor the gas pedal. You should see the boost comming up, and (when standard) it should stay at 0.5bar.

If you would like to keep running higher boost, install a chip and get it set up on a rolling road.

When you turn the engine off and start it again, the ecu doesn't remember the boost overload and you car drives ok again (until it has an other boost overload)

Hope this helps

Belgian Greetz,

 

as said above, its your ecu cutting in when the boost gets too high. when you switch the engine off and back on it resets the ecu which is why it wont cut in untill it boosts high again. mine does it at 5k upwards in 3rd and upwards. im getting a chip soon to sort this.

 

ok thanks is there any way to sort this out and how much because im starting to run out of money fast and i wanna sort her out cos i really love old school fords theres just something about them after it does it the firt time thou it does it at almost any rev also is it easy to do a clutch and does any1 know what the knocking is when going round a right hand ben or accelerating oh and also when driving normal just cruising theres a sort of squaking sound thanks again for everyones jhelp

 

To sort out the overboosting problem, just check out the rubber hose that is going to the actuator. Most likely it wil be broken. Just replace it with a piece of hose of the same size.

The knocking and squaking could be the 2 rubber pieces that hold down your font anti-roll bar together with the rods that go from the front anti-roll bar to the dampers of front suspention.

Fitting a new clutch is an easy job, just get a haynes repair manuel and follow the steps. Do fitt a full clutch kit (clutch, clutch cover plate and bearing), because you don't want to this job 3 times just for fun. A standard kit will do if you car is standard.

Belgian Greetz,

 

ok people like to say thanks once again for all your help il have to check that pipes i got the head off today ready to replace the gasket only took two hours so not to bad and hopefully should be back up and running tommorow

 

Hope you used a proper Ford HG and not a motorfactors one or you'll soon be having the head off again.

Hope you sort the problems mate as FRST ownership is a lot of fun when they are working right.

Can I also direct you to www.fiestaturbo.com as that is a very usefull site that only really deals with Fiesta's.

 

thanks again p0eople n shit no i dont think it was a ford one also i had it running for 5 minutes after it never overheated there was still alot of smoke thou and it sounds like a tappy 1.1 also found today that thu rubber hose coming of the top of the actuator that goes into a t piece the little piece of rubber hose heading toward the turbo is split could this be my problem with the boosting when its under load cheers also what could i have done for it to be running really crap could if have not timed it up right or more serious cheers again
