ive got a esc rs turbo with a 2.0l zvh and efi.Once ive driven the car for about 5 miles and im stuck behind traffic the engine dies as if the fuel stops flowing, i loose revs for about 1-2 seconds then she fires back up again, it doesnt die long enough to stall. If i stop and let the engine idle then she cuts out altogether. ive changed the injectors,fuel filter and checked fuel pump and put a brand new set of leads on her. Now i changed the fuel filter it does do this less often but it is still doing it. Any ideas? many thanks

The only other thing I can think of is your airfilter or maybe your spark plugs. Sorry if thats no help. :S

You've covered all the fuel side. I'd say its spark.

What loom & management are you running?

does efi have a cold start valve? it seems to be a simular problem as the mfi's have with the cold start valve possibly sticking and flooding the engine?
