340 1.4 rough ans slow idling
Hi there, I'd be grateful for some advice.
My 340GL manual has run well for years. A few days ago I filled up at the local Asda Petrol Station, after a short distance the car was tending to stall and tickover slower than usual and rough, something like 200 RPM. The next morning I started the car and again had the same problem I disconnected the fuel feed to the carb and pumped out about 2 litres of fuel. Reconnected the feed and car ran OK. The next day I did a round trip of about 10 Miles and the car was fine. However, today the car is playing up with the same erratic and slow idle. I did contact Asda about the possibility of contaminated fuel, they responded on the day that I filled up, several hundred cars filled from the same tank and no reported problems other than mine. I have checked distributor, rotor arm, air filter and for air leaks around carb. The ignition leads are fairly new. Of course, MOT is due soon, so I need to resolve this. Many thanks in advance. |

If so, it sounds as if you have a build-up of condensation in the tank, worth trying as a "first port of call". Wait until the fuel level is down to ~1/4 tank (about 3 gallons left) then add 2L of meths to the tank : https://www.toolstation.com/methylated-spirit/p99550 Cheapest way of buying it at that volume as far as i know. This will emulsify with the water and allow it to be burned off normally. If it doesn't work, it's cheap enough to know you've tried a quick, cheap and easy fix that has got rid of the condensation. Note that the best ratio is 1:10 so more than 3-4 gallons of petrol will dilute it too much to have any real effect. |

I going near Toolstation today, I'll get some meths. Yes, more temperamental when cold, but still bad tickover when hot. Of course, Ive got over half a tank of petrol. |
Apologies for the typo in the title. Must concentrate!
Testing the car yesterday, Ive got good brakes on the 340, was going to go through the second set of traffic lights, decided to stop. Range Rover to the left of me decided to go through, he got flashed. My £6 dashcam filmed this. https://youtu.be/SQHPWMLzR_w |
Just got back from Toolsation to get methylated spirits, car still playing up, bit like kangaroo petrol. Relatively new thing, engine ran on a bit after turning ignition off. Does not usually do that.

Just noticed another error of mine, I'm registered here under two names, this one and 340man. |

Pumping from the carb feed pipe would also mean you're pumping from the bottom of the tank so likely to get a lot of the condensation - could be why when you did similar and got the engine started you pulled through some petrol instead of condensation. |
