just after a bit of advice please my 320 cab trys to stall when you touch the acellerater before reving normal even when warm also exhaust stinks of fuel and quit smokey (white) and only seems to be doing about 20 to the gallen is this normal ?

Check your TPS

whats the TPS please

throttle position sensor!
under throttle body.

ok thanks what does it do exactly is it something you replace or would it need a good clean

Take the rubber intake boot off and you will see it under the throttle body.
they can fill with oil,

will this help the fuel smellin smoke as well?

It tells the ecu which of the 3 engine maps to use, idle, normal or max power. All use different fueling and ignition settings. You should also check the basics of air filter, plugs, rotor arm and dissy cap. While your checking the TPS for correct operation (do a search for tps tests) look at the injector loom connector c191 have a look at this link:

Also CTS (blue temp sensor)

i shall try those ideas thanks for the help

While the air intake pipe is off, check out the round plug and socket under the inlet manifold, fitted to the black metalwork, where the injector loom connects to the engine loom. Especially look under the lower rubber boot, where water gets trapped and rots through the wires.

can you let us know how you get on

im having similar problems with my M42 idles rough lack of power in the lower range and when she eventually gets to the higher range i get a strong smell of fumes bit like petrol inside the car she is definatly running rich, and even with my mods she is drinking a lot!

This problem is a nightmare! I am looking into mine as we speak

seems pretty common i though i had worn piston rings or a leaky head for the lack of power but compression is still good bless her!

I would say last week i cleaned her out all over and was much better i think now the cold weather is here its just one of those things.

ive found a split intake pipe the flexy pipe right before the sencer think that might be an issue

This would cause the hesitation, but not account for the exhaust smelling of unburnt fuel.
Take out a spark plug and tell us what colour the tip is.
