Fuel Heating???
Discussion
Has anybody had any experience of fuel heating on the Cerbera before?
My old man's car appears to be struggling on hot days when the tank level is low and when slow moving in traffic
The gauge appears to show fuel but the car can suddenly stop or drop cylinders. Let it cool down and it's OK. Also can run a little rough when running in town even on cooler days. Coolant temp sits at 90 (95 on hot day) and can cycle up to 105 in traffic.
Worried about it running glean at some point - apparently one manifold bank was glowing red when he tried to restart last time.
The engine's had a full rebuild and the throtles balanced (although I'm suspect of this as I don't believe the adaptables were reset).
Was thinking a remap would help ensure the fuelling was spot-on as well as the fan fix at the same time to stabilise the coolant temp in traffic.
I'm away in Austria at the minute, can anyone shed any light?? Fuel heat was my first thought, others may have more experience of this...
Cheers,
Rob

Sounds like a problem with the HT leads or coil packs perhaps, if the cylinders intermittently drop out. Are all the HT leads properly seated and in good condition? You could also test the coil packs and check their overall condition, but I don't know what resistance they ought to have on the primary and secondary windings. Generally the primaries should have a low resistance (a few ohms, sometimes less) and the secondaries a high resistance (a few k ohms).

It could be the fuel breather blocked. I had a similar problem last summer. Hot weather, half a tank of fuel and engine struggling and sometimes dying.
When/if it happens again remove the fuel tank cap. If there is a big whoosh of air then the breather is blocked ie the black rollover valve itself (fastened above the tank to the fibreglass bulkhead) or its hose.

Thanks for the comments.
HT leads are fairly new but I will check when I'm next back.
Fuel tank breather sounds interesting Mike - I've noticed in the past that the fuel tank always lets off some pressure when I take the cap off. I'll have a look for the breather - thanks very much for the heads-up ;-)
