Engine Running Lean Issue

[Bryan Moore]

Has any body got any sugesstions how to fix a fault which occures when my 260 gets hot when stuck in standing traffic. It starts miss firing and the engine management fault light has come on. The fault reads the engine is running lean on the left bank.

It is a hot under bonnet situation. The fuel rail gets overheated and clears when cool fuel is pumped through. TADTS.

I think that must be why I rev the engine in traffic, A) to tell people I am there. 2) keep the fuel rail cool due to fuel passing through.

Only once had the problem in 5 years, 'twas at Brooklins last Sunday. Cleared itself after a minute.


If you have the carpet under the bonnet, Remove it.

That's why I'm going down the bonnet vents road.

Or maybe we should built in a small hydraulic/electric thingy that opens the bonnet 10-20 centimeters when stuck in traffic jams.

My mate showed me his Escort RS, it has rear lifters (solid) to let the hot air out.
(Gets me thinking,"Special hinges")
