xe problem

[16v Nova Kev]

ok the engine starts and runs on idle fine.touch the loud pedal it dies. but rev with the t/b large butterfly by hand and it revs fine,:confused: :wtf:

[Mincyballs]

in the words of the virgin mary.....Come again? I see what your saying but still doesnt make sense

[16v Nova Kev]

ok i will try again
1. engine ticks over fine
2. try to rev with acc pedal and it dies
3. rev by hand at the t/b on the large flap it will rev
4. touch the lever that controls the small buterfly and it it dies

Is the acc cable catching on something?

[Tim Harpley]

Check the breathers aren't blocked small one from cam cover gets clogged small drill bit or pin into throttle body with carb cleaner works,done loads at work,if not could be air flow meter.

earth strap?? and the engine is earthing thru throttle cable.. perhaps?? i know its random, but i've never heard of a throttle cable causing any faults before..

in gonna try another afm to rule that out and never thought about the breathers:thumb: :thumb:

I cant think of any reason why revving on the throttle body side or on the pedal would make such a difference, I take it your revving the engine in the same manor on both sides of the cable?

[MK999]

XE has a twin butterfly, its something to do with the smaller one. As when you hit the pedal it moves this first, and also when he moves the smaller butterfly by hand it dies. Is the TPS on the smaller or larger one? I'm guessing smaller?

[16v Nova Kev]

even if i pull the cable whilst standing over the engine it dies. i can only rev it by manually operating the large butterfly lever, i will try and get a vid tomorrow.

[16v Nova Kev]

tps is on small one but i have changed the tb and no difference

[MK999]

Iiiinteresting, I assume the smaller butterfly is not under water, attached to a CO2 fire extinguisher, etc? lol

[16v Nova Kev]

nope lol im gonna try some things out and see what happens. bought it as a running engine too.:roll: :(

[AlexW]

It is running lol

If you open the big butterfly slighty and then open the little one, what happens?

[db_1.2]

Tps ?

That would be my bet. Unplug it, it should run without it, I drove mine for months with it unplugged.

cunny funt i had to do lots to just get it running in the first place.
and to answer your? engine death happens:(
