More GT woes, severe loss of power.

[( =Jamie= )]

Hey all, got problems with my gt. Low down i get hardly any power what so ever. My foots at the floor and nothing happens. Need to dip the clutch and build the revs right up in order to get going. The car sort of chugs along, no strange noises or bangs. Desperately need a diagnosis as i start work again soon

May well be the air flow meter. Try disconnecting it and running with it like that.
You'll find it just upstream of the air filter plugged into the air trunking.

Seconded, when the afm gave up on my 156 it would not rev past 5k. Easy to change but I think there about £140. stay away from the cheapies on eBay, some work, the majority don't seem to.

It's a Bosch part, unreliable German rubbish lol.

Ps check the rubber pipe from the air box to the throttle butterfly for splits. Common and robs you of hp!

Thanks very much guys for all of your help, i'll check that out and hopefully that'll be it.

Gona have o go at changing the air flow meter. Not very competent so asking for a bit of guidance on the DIY front. Where abouts do i start??

Or a intercooler. Had the same problem with my Phase II Uno Turbo.

On my 166, the air flow meter is a black cylindrical object (made by Bosch), and it is attached by some flexible piping, to the top of the casing that holds the air filter. The casing holding the air filter is a big black box that sits behind the headlight but quite low down in the engine bay on the passenger side. You'll need to undo some clips at both ends of the meter, and the piping attached to both ends of the flow meter should pull off. Replace this with the new one, re-attach the piping and you should be done.

I think my 156 had a similar arrangement, so I am guessing these instructions can't be too far out for a GT (same engine as 156).

There is a pic of the air flow meter on

All the best.

The symptoms of the car do seem to be as descibed like the meter but i went to have a quick look too see what i thought and found that the car now doesnt start, could this meter cause this? if its a case of changing that then its cured thats fine, but if not then there may be something else wrong??


When trying to start, the car coffs and splurts and wont idle at all, could this sensor or meter be broken or faulty in such a way that the car will no longer start?


cheers

Sounds extreme, but it could be the AFM.
Just try unplugging the connection to the AFM and try it then. The engine should just run at a default safe setting.
