Now i'm going to try and explain this as best as possible so bear with me.
I own a W reg Megane 1.6 16v Sport with 57k miles on the clock.
When i'm pulling away from a junction or travelling up a hill and i put my foot down, i suddenly lose all power and the accelerator is unresponsive for about 1-2 seconds. It seems to work ok soon afterwards but the problem repeats. The weird thing is, i don't have this problem when my trip computer reads over 140 miles left. As soon as it hits 135-140 miles to go I start losing power. I don't get any warning lights and whilst i can replicate the problem by driving up a hill, it feels quite random around a corner.
I've read many threads on this very site about meganes losing power but none have mentioned anything about having lower fuel when the problem occurs. I've also read about many fixes, from a fault in the ECU
to a simple earthing problem. I've just been getting around the problem by treating 140 as the empty point of my fuel tank.
My main theory is not that the fuel isn't igniting, but more to do with the fuel intake, it doesn't feel like its actually taking in any fuel (if i'm making any sense).
So here is my question, after seeing a lot of the solutions. What do you think i should try to fix first? I'm a little strapped for cash at the moment so anything i can do myself to attempt to fix it would be brilliant. I also don't want to spend money on parts that don't need fixing, so any ideas you may have on diagnosing the problem myself would be much appreciated.
In the bad news that it is the fuel system, can anyone give me a rough figure on how much it would cost?
Hope i was clear enough, if anyone needs any information or wants me to test anything out let me know. I currently have my trip computer telling me i have 90 miles remaining as i wanted to be in a position to test any ideas people may have and to see if my car is reading fuel correctly in the first place.
