Gas pedal/wheel bearings.....

Yet Tumble looked as well Lynni and couldn't see anything wrong with the post above, you may be angry that you've not got a car, but i think you should probably think on the bright side and be thankful the throttle didn't jam open on the motorway and put you in a very dangerous situation.

there wasnt anything wrong with the throttle, unless the throttle does the job of what i was explaining in the post above? iam narked, because this is gonna cost me more... more on the labour, the parts etc etc and also the inconveniance of not having a car for the day.... may sound silly, but i need a car to go EVERYWHERE nowhere is walking distance for me at home

well if its similar to Vauxhalls of the age, they have something called an "Idle Air Control Valve" and previously also a "stepper motor"

The first one is in charge of the "idle" or "tick over" and it controls the amount of air precisely......and they do wear out
it is the most likely thing to ALSO cause the engine to rev on its own

It would work one day, and then just stop the day after hence not picked up on a service.

Now...what is a service? Its a fickle word.

Even Mainb Vauxhall dealers offer different levels of "Service". Why? Because the market demands it

To ME a full service (exclusing timing belt which is every 4 to 6 years according to model) is a big job...it costs between £300 and £400 and invovles the wheels coming off, the brakes coming apart, the hinges on the doors being oiled, the pollen and fuel filters being changed and the car being driven for 5 miles.

We make about £90 profit out of that £350...the rest goes on costs...overheads...courtesy cars, insurance, staff wages etc...

However...Kwik Fit offer a full service for £99 inc an MOT that costs nearly £40 trade...go figure...what got missed?

All of it


So WE offer the same....we offer a service for an Omega INC an MOT for £160 and an interim service for £69 inc VAT.

But lets be clear...we dont drive it and we dont even take the wheels off....brake cylinder leaking? might be, cant see with just a torch.

The simple fact is.....its gonna hurt this one...

for people who are not mechanically minded, you gotta spend the dough on service

I know it hurts...its big money...but unless you know whats what, you're stuck.

[TiG]

And even if they had picked it up on the service Lynni would have still needed to have paid to get it fixed right?....

[Zak33]

yeah..but she has the arse cos it was ANOTHER visit, rather than more cost..least I think so

[Tumble]

That's about the top and tail of it yeah.. the inconvenience rather than the cost...

Wheel bearings certainly don't just fail - they tend to go gradually. I'd certainly be asking the garage for an explanation as to why it wasn't noticed at the previous service - especially if it was only 2 weeks ago.

As for the throttle problem, you could try changing the throttle cable itself - sometimes it can fray inside the out casing, causing it to stick, however, you should notice that the actual pedal doesn't return when the engine is revving. However, I don't think it's mechanical.

From your description my first thoughts were that the clutch was slipping (lots of revs, not a lot of movement). However from tumbles description is doesn't appear to be that. I'd be tempted to give the throttle body a good clean out (tumble will understand!) with some carb cleaner, as it may be the throttle butterfly thats sticking, NOT the cable.

I would say about that same, if the cables not sticking, clean out the TB, particularly under the butterfly as this is where carbon builds up, get a toothbrush in if you can with some carb cleaner. I don't know what car it is, but if you have a manual choke, makes sue it is fully retarding when the cable is pushed in, if not the car will be running on choke all the time, hence high revving when changing gear.

Edit: Are you from the Isle of Man Lynni? Looks like your sig is overlooking Snaefell?

[Tumble]

tis South Barrule in the sig... and she aint from here.. yet


aaanyhoo - it's been back to the garage now, and bloke's been onto Ford about it (tis a Ka) and their recommendation??? UNPLUG THE AIRFLOW SENSOR.... just get rid of it... and it'll work fine apparently..


/wanders off muttering about all this new-fangled engine management business....

[doll]

Hmmm, remain scheptical to that one. Surely if it was the AFM then they would replace it. Not having it connected may get rid of the problem, just depends on whether the management system will run correctly without it. Sounds like a good time to throw an induction kit on it, max airflow that should sort it out,lol!

Wherabouts do you live on the IOM then? We have friends over in Onchan, gorgeous part of the world! We were over there in May, just before the TT. Shame I could'nt find a job over there, i'd move tomorrow!

[Tumble]

I'm in Douglas.. I can see Onchan out of my window tis a grand place to be for sure...

[Crazy Cricket]

Has the car in question had any of it's wiring loom replaced? There was a TSB about the possibility of engine flare betwix gear changes, it advised the replacement of not only the throttle postition sensor, but the wiring leading up to it.

Removing the MAF will just result in the car using a default map in the ECU I would of thought, can't see how that could help. If it's dead then it needs to be replaced.

[Tumble]

Well, apparently that's what Mr Bloke at Ford said.. it's not an intelligent engine management system for sure... I think unplugging the sensor is just a way to trick the car tbh... I agree tho that it isn't a long term solution... seems a bit 'coywboy' tbh...

I might give the Ford guys over here a bell, see what they say......
