My 93 Micra has taken to random hiccupping! It feels as if the ignition has
suddenly been turned off. It nearly always happens (when it does at all that is)
when I press the accelerator to pull away in first. Lately it taken to happening
in any gear!

Today, with engine idling, I jiggled a rubber pipe that sprouts form the
camshaft cover - and the engine hesitated. I couldn't make it happen again
though!

There's quite a vacuum "whooshing" noise when I take the fuel filler cap off - a
clue maybe?

Any ideas what could be causing this?
Thanks

Possibly throttle body - several hundred to fix! Unless its just the 
electrical connector a bit loose.

My daughters does the same - replaced plugs, carbon canister etc.


Have a look at www.bba-reman.com

Thanks for info - I hope it isn't this!

We've had similar problems with a Peugeot 1800 406 petrol and a Proton 1.5
petrol - turned out the MAP (Manifold Absolute Pressure) sensor had got
'old' - this is the sensor that tells the fuel injection how much
pressure/vacuum is in the inlet manifold.

The symptom was a couple of minutes after startup the engine 'misses' for a
moment and then picks up again.  Occasionally it will 'miss' again for a
moment to a couple of seconds - often at the worst possible moment.

Replacing them was a DIY job and took about 15 minutes for the Peugeot and 5
minutes for the Proton - the new Peugeot sensor cost just over 40 and
Proton wanted over 100.  Needless to say, the replacement Proton sensor
came from my local scrapyard for 1!  Problem solved, and no more children
through my windscreen!
