hello all
having troubles with my fiesta turbo,when i put my foot to the floor and try to rev it,it wont rev up! but if i press the accelerator very slowly it will rev?? also it is an intermitant fault,seems to be worse when its been running for ten minutes or so....any help on this would be greatly appreciated.any 1 any ideas please??
thanks
paul

 

no body got any ideas?????????

 

hmmmmm

 

when did u last have this set up? mite be a sticky cabel??

 

Could be the throttle position sensor mate.

 

if it is the throttle position senor unplug it. If it still play's up it's not that sensor

 

tried unpluging tps but still the same..i havnt had the car set up at all (i havnt had it long)

 

is it miss firing?
if so is the head gasket gone?
might have an air leak?
coolant sensor faulty?
charge air sensor?
crank sensor?
cam sensor?
connectors on the wrong plug?
just check these type of things on the car if you are wanting to do it on the cheap its just trial and error replacing engine sensors im afraid.

 

or even plugs, leads, coil pack wiring?

 

no it aint missfiring..its like it aint gettin enough fuel,its fine when its first started but then plays up after 10 mins or so...gona try a few sensors...anybody think it could be fuel pump??

 

I had the same thing on a later festa which turned out to be the timing was out!
First thing i would change would be coolant temp sensor(cheap an easy to do)
Next i would try dropping the exhaust could possibly be blocked i have come across this before with similar symptons!then i would check the timing.i wouldnt think it s the fuel pump coz they usually just give up an you wont get any fuel up,these are just my sugestions from my expierinces but id always start with the cheeper options first!
