Hello all,
I've got an unusual issue that I'd like to sort. It's the most annoying kind of issue - one that you can live with but doing so means a sub par experience.
I semi regularly drive a 120 mile round trip in the cappo, meaning I use about half a tank each time. So I usually fill up on the way out and experience the issue on the way home.
With less than 10 miles left - the best leg of the return journey - the cappo starts to lose power under WOT. The issue is repeatable - the car is fine at WOT up to around 5000rpm, then power is cut and the car doesn't want to creep past this rpm. Shifting up a gear clears the issue until I reach the same rpm. It feels like fuel cut, just more aggressive since it's occurring at peak torque.
I had a similar issue last year when I took it to a track. On a left hand hairpin the car would lose all power and take a second or two to recover. It had a full tank at the time. I replaced the fuel filter (some pretty nasty looking, orangey fuel came out the tank side of it) and the issue went away.
So I expect this is a fuelling issue, most likely some rubbish in the tank blocking the inlet.
My questions to you all are, has anyone experienced a similar issue? Any idea what's in my tank? Can I syphon the tank empty out of the filler cap? Or should I cut to the chase open the tank up?
