Motor is a 1995 Corsa GSi with the 1.6 16v ecotec lump in.
After running for long enough to warm the engine up, could be 10 mins normally, while driving it will lose power and appear as i its running on two. The exhaust is really loud, feels like a fuel blockage and appears to run lean judging by the heat from the whole exhaust system when i pull up, everything is steaming hot.
I have changed,
Injector wiring,
MAP sensor,
Lambda Sensor,
PLugs,
Leads,
Timing checked today and perfect.
TPS appears to be working perfect with running diag tests on snap on scanner.
Any other ideas please? Im really starting to get pissed orf now.
What sensors or problem could this be? The guy who had it before me (and i had before him LOL) put £7 of diesel in by mistake but filled up with £26 of unleaded to dilute it. Drove 7 miles home and immediatly drained tank and changed filter. Drove fine by me for next couple of weeks. Then this problem started and hasnt gone away since.

Headgasket was done along with rings, valves, stem seals about 2 years ago and done about 7k miles since.

Start your car up with the exhaust blocked off at the back and see how long it ticks over for before it stalls

Ahem,
Arkams Razor; The simplest answer is usually the correct one.
One thing that you seem to have forgotten (simple little thing) is the fuel filter. DERV & petrol dont mix (duh!) so its not being dialuted at all, in fact the DERV would have sunk straight to the bottom of the Tank (where the pick up is so uh-oh!!) once it got moving it would have mixed it a bit but the bad news it that when mixed it breaks down into a waxy substance which will clog things that it shouldn't.
Now with fuel contamination its recommended that the whole system is replaced if the car is driven or engine is run, but its not nessecary, however it does need to be cleaned. Change the fuel filter and run redex or other fuel system cleaner into the tank and run it for a while. I would also fit another smaller fuel filter before it gets to the injectors (little clear thing from motorworld or something) that way it'll stop anything getting to the injectors. You might want to pull the injectors out and give them a squirt of carb cleaner too if the problem persists.
