hi boys and girls i bought a fiesta turbo (OFAB) a little while ago and done a shit load of work on it to get it on the road and now its on the road ive found another problem!!!!

first ill say that when i bought it and drove it back it was so fucked and running shit that i wouldnt have noticed it if it was there or not

basicly whats happening is when i start it from cold it fires and runs lovley but when i touch the throttle the revs dip abit before picking up, and when i pull away and when driving when cold its very missy like the coil pack is going tits up but as it warms up it runs perfectly and then when it up to running temp it starts to kangaroo abit and u cant drive on lite throttle, it has to be accelarating or going balls out, also on lite throttle as i back off it sort of bogs down and then when to touch the throttle again it sort of bogs up (if u know what i mean) like it comes back into life with a jerk. theres no missfire when hot though and doesnt cut out (yet)

i thought it might be coolant temp but im not sure as this is the only frst ive had that is giving me grefe

some one please help me

the parts i fitted that could be related are

car loom (but i know its a good one)

idis mod

map sensor

co pot

isvc

also what exactly does the co pot do????

please help!!!! im driving this car every day and its driving me up the wall!!!

 

Rite sorted the missfire, it was a dodgy ht lead but i still need to know wot the other problem is, please help

 

I feel your pain lol

 

FOUND IT!!!!! ithought it might be coolant temp for ecu so replaced that which was an arsehole job with a hot engine and it made fook all diference! so on to the next sensor in the firing line and bosh got it!!! it was the tps which i did think it was before but every were on tinernet i went said they never go wrong but hey mine did

 

the tps on the rs turbo are prone to breaking and causing said kangarooing who ever informed you that they not prone to breaking obviously has never owned one lol

 

yea i know ive found that out recently from a mate of mine that works on tvrs and he said alot of them use the same tps and they always go wrong due to the heat of the engine cooking them

 

hi mate i have just bought a fessy today it does run but the cams gone what i have read here i will remember if mines does the same thing

thanks glyn

 

hi mate got a similar problem where is the tps??

 

TPS- Throttle position sensor is On the left of the throttlebody below idle valve..


black plastic sensor with a multiplug on it.

 

Hi ,i've not long since bought my fessy turbo 1991 red and having may miles enjoyment out of it already got a few issues and will soon start a post going on here hope fully soon if i get a job this week .

The cam hadn't gone thank goodness , it's wonder i didn't kill then engine the oil was low so cam was tapping and i thougt the cam had gone till i check and seen low oil ooops

all seams well after a month i went out in it at the weekend and i was well happy with how it pull's and drives more so now ive fitted new gmax kit

Hope to see many show's this season and many fessy fan's too
