Popped down renault dealer @ lunch to get some parts, on the way back I fill up with a full tank of petrol then drive back to work (2 minutes) and park the car up front first, surrounded by hedges in a little bay. Car is on a slight gradient, front being higher than rear.
Leave work 2.5 hrs later, quite misty, been raining. Get in car go to start it up and the engine keeps turning over and over and wont start! So leave a few seconds and then try starting with foot down on pedal. Car starts OK but i take my foot off to quick and it stalls. Then wont start - try about 4 times.
Leave the car 5 minutes, go back and try again - starts after a few attempts.
Does anyone have an idea what is going on here? Ive got a decat pipe, BMC CDA - cold air feed and Magnex exhaust. I checked the cold air feed to make sure there wasnt loads of water in it. Could it be the lambda sensors?
