If you think about it, its extremely dangerous!!!

I was driving at 120km/h and had to swerve off the road, imagine if you couldn't, you'd be stuck in the fast lane causing a huge backup and more than likely a lot of accidents!

If it happens, here is a little tip I got from the UK, don't drive over 40km/h after switching off the engine and restarting, the problem won't appear till you go faster. It may help you get back home or to a garage.

@ Jules: Thank for the input. Do you have a copy of that Ford Buletin that I could arm myself with ? :)

I would like to replace that part as soon as possible.

Jules wrote:Ok firstly.

That is a common problem and a DESIGN MANUFACTURING ERROR! Not anything to do with your particular car! If it cuts power TOTALLY like you said yours did, it needs to be replaced.

Read up on this forum my experiences and there is there is a copy of the Ford Buletin to each dealer about how to repair it.

To give you a breakdown of my 1.4i Trend (2005). I was driving down to Durban 3 months ago and it happened and I had to turn off the road quick as well. I took it to the Ford dealer in Umhlanga and they reset the computer and redid the programming. They told me if that didn't work I would have to pay for a new one. All went well for the weekend, till I had to come back to Jhb, then it started again and badly!

So I took it to Ford in Randburg and they said I'd have to pay for the part. I blew my top at them and told them what I thought of them. They said it was my problem! So I then went back to my car with ammo, I had made a list of this forums' members and both of the UK Fiesta forums' members and then showed them the official Ford buliten to them regarding it. They then suddenly changed their tone and replaced the part free of charge.

The part that they are supposed to replace it with is off the newer face lifted Fiesta. Ford was well aware of this problem so redisgned the parts. So it only effects the pre-facelift.
Respect the blue oval.

I had an EAC Failure a while go. Took it to Ford they had to replace the TCM cost me nothing. The dealer where I bought my car just paid for the labour which I think was R250. But the part was covered by the warranty. And the car is a year old.

sheesh - this is quite a hectic problem with the pre-facelifts.......

I never had this on my 2004 1.6 Trend Fiesta thank goodness - but seeing as Jules had it with his 1.4 Trend... this could affect many many motorists!

As for the dealers trying to charge for the fix - I would pull the oke over the counter - throttle body is engine baby - engine is covered for 3 years or 100 000 km's! End of story!

Sheesh Devenk, you do a lot of driving, I don't think I could wait that long!

Mine was done in a day from starting the argument to a nice clean car all fixed and they had to order the part.

Guys just tell the dealer to look at the grounding points located in the footwell on the drivers' side of your car....

There are quadruple redundencies built into the electronic throttle control strategy, if the earth point on one of these are not grounded properly, or there is some paint that cause the ground to be bad, then the voltage correlation is affected.

Let them check and clean the grounds properly where i said...this should solve the problem.

Its not the ETC unit thats faulty.....it's just where the symptom occurs....don't shoot the messenger!!

Ciao

Replacing the throttle body wont solve the problem...it might go away for a bit but it will return.
