stutter has come back
driving along all good -
every few minutes... no matter what the speed or gear I'm in the van momentarily hiccups then drives well again then hiccups then drives well for a few miles... then hiccups then .... etc etc... doesn't matter whether engine warm or cold or speed slow or fast...
to date -
renewed fuel filter - air filter - spark plug leads - distributor cap - spark plugs - ignition module on l/h side of engine bay - fuel pump and rod (though didn't pack with grease) - checked ignition timing - fine - new coil - renewed vacuum hoses - had a spray around with carb cleaner and cleaned out main jet - spray round hoses in engine bay to see if engine speed changed - all to no avail -
now in chin stroking - what next? mode -
any ideas good people?

Which engine? If the Petrol DG have you checked the small filter on the inlet?

petrol dg 1900water cooled -
yep
had a look and clean of the little cone -
next -
rotor arm - n checking all the hoses again -
these intermittent stalls are a headache

blocked carb jets?

Is your exhaust blowing at all?

Clean the copper contacts in the dizzy cap, and scrape/clean the copper connecter on the rotor arm too.

try redex fuel cleaner in tank cured mine you may have to use it in a couple of tank fills, mine was a real bad case and 2 mechanics couldnt fix it they replaced the same as you have had replaced.as a last resort i tried redex which i was scepticle of but it works.im a believer tesco asda cheepest place to buy.

Pack the fuel pump base with grease, that's not the problem here though methinks.

Any pattern on when it does it ? Mostly when hot or cold ? Did you clean out the carb filter as well as replacing the inline petrol filter ? Have you checked the filler neck for leaks ? You could be getting water in the tank that way ?

Ian.
