pug 306 seems to die whilst driving.

Hi all I have a 306 1.8 16v 1997 r reg. When you start it up its fine but
when driving it can suddenly lose power whenever it feels like , and usually
once this starts it idles irrationally.So far I have used redex which didn't
do much but I've been told to change the plugs , leads and fuel filter.To
try and put it another way. When your driving along with you're foot on the
throttle it will suddenly feel as if you've turned off the engine , but if
you wait a couple of seconds it will rectify itself. Any help would be much
appreciated.

 

i had a similar problem with my 1999 406 hdi
not sure if the 306 is the same but here goes.
It would lose power and the revs would drop down to tick over no matter what
you did with the accelerator pedal (great fun when you are pulling out from
a junction or overtaking).
It took over a month to work out what it was.
In the end it turned out to be the brake light switch above the brake pedal.
This meant that the brake lights would come on
even when not actually braking, this in turn meant that the ecu thought that
the brake and accelerator had been pressed at the same time so it would shut
off the revs down to tick over until the brake pedal switch turned off
again.

Hope this helps

Cheers , at the minute any help is great.I'll check it out thanks.

 

The engine doesn't drop down to idle when it loses power I mean it holds back
as if you have switched the ignition off with it in gear. but it doesn't do
it all the time which is annoying.

 

Could this be the dreaded corroded earth lead raising its ugly head again?
Wouldn't be a bad idea to check this and the battery connections as well
while you are about it.

Plug leads or intermittent coil pack perhaps?
