Thought I would share this one with everyone as it's something that's easy to overlook and could cost you a lot. I've been trying to trace my stalling problem; the car has been cutting out at low revs of late and has been hunting at idle. It also seems that upon starting from cold that it will initially idle at random revs (anything between 1800 and 1000 rpm) with no consistancy. Under load the car pulls fine but can kangaroo once I come off the gas.
So, I dropped into a main dealer and had a diagnostic done a couple of weeks back as I thought it might be the lambda, but it got a clean bill of health - no faults found, so it pointed to a mechanical issue/non electrical anyway. Okay I though, not the MAF at least, perhaps it's an airleak in the intake system. So I went up to Halfords and got myself a hose clip pliers (essential bit of kit - don't know how I did without one before) and prepared to start taking the intake apart. I thought I would check all the piping up to the throttle body and give the butterflies a clean while I was at it, unfortunately the weather turned and I knew I wouldn't get a good run at it so I held off and decided to do a full inspection of the engine bay between showers. This was an eye opener....!
I found 4 pipes that had completely lost their hose clips, 3 of which were not too serious but disturbingly one of the missing clips was from the fuel rail and immediately upon inspection it started leaking fuel
Now, all I need is some new clips and my fire hazard is sorted, but I'm wondering how long I've been leaking fuel onto my cylinder heads and how lucky I've been not to have an engine fire? For the sake of a ten minute inspection I strongly advise everyone to inspect all hoses regularly!
Tomorrow I might even find the answer to my low revs issue
