random stalling - cold weather?

[Cory]

so, i have a 1.6 carb driver. she is usually good as gold. havent been driving her much lately because of the weather. but i drove down the motorway the other day, all normal and smooth driving. pulled nto the services, slowed down for the speed bumps, and the car just stalled, and then decided to every time i stoped that day.

drove it round town for the next couple of days, was back to its usual self.

then drove back down the motorway again today, and had the same stalling problems.

is it fair to put this down to the freezing temperatures, or may their be something wrong?
fuel filter, co2 mix, dirty carb maybe?

thanks for reading

Sounds like carb freezing due to the speed of the motorway. I would suggest getting a hot air feed from the manifold and blocking off the cold air intake for winter.

as above, check the warm air pipe is there, and you still have the metal shround that fits around the exhaust manifold.  check the 2 vacuum pipes on the side of the airbox are still plugged in at both ends and havent split.  if all that checks out, whip the airbox off but leave the vacuum pipe connected to the rear of the car. start the engine and look into the front of the airbox to check the warm air flap actually moves. if not the vac unit has failed or the vacuum feed from the carb isnt working, perhaps due to a faulty air temp sensor.

can check by manually sucking on the pipe to the warm air flap mech, if it moves the problem is further back, if not its the flap itself. you can wedge the flap open then put a screw thru the side to hold it shut, that should sove the issue till you can get a working airbox

ahhh, thats some awesome info, im not too sure about the heat shroud. as my car has had some mods inc.

gti cams, gti manifold + full exhaust system. also, all done at tsr with reciepts, so its quite a punchy little driver
im pretti sure its not the standard carb either, after comparing it to the haynes manual.

if its missing on some carb/gti have a small shroud which is held on with 2 nuts to the back of the manifold. no worries if the holes are too big or studs sheared off, on my driver i held it on with 2 jubilee clips held together. solved my stalling issues straight away

ah awesome. will check it out when i can go outside and not have frozen hands
