Engine has not complete exhaut, only headers, is it too much open for it?

more information needed...

can you rev the engine in neutral?

does it stall only when using clutch?

Sounds like timing or fuel(bosch Air mass sensor hooked up??)...

Check for air leak...especially main hose from Bosch air flow sensor

check ALL wiring

Movie about rev on neutral is on link

It stall only when using clutch, AFM and ECU is not from same car, maybe that is problem

Still have problem, no air leaks, i think it has too much fuel, spark plugs are black

like you say...probably running too much fuel and timing not advanced enough...

02 sensor hooked up?? Working?

Also, I can run my car so rich it puts out black smoke to hurt your eyes....BUT it can still run in gear

Have someone use timing light, put on parking brake, and slowly let out clutch in 2nd gear...check timing advance

does the car move in neutral (rear brakes frozen??)

Did anyone mess with the air flow meter (big box on air intake?)

I found the problem, one resistor in cable was problem, now i have new problem, too much fuel, how to reduce fuel on l-jet, rotate plate on AFM, clockwise or counter clockwise, how much??

Try disconect cold start injector when running and see if it makes any difference. I had a problem with a faulty one before.

I'll try, thanks

ECU was the problem, injector pulse on 1500 rpm 20 ms, now I have 1 or 2 liter of petrol in oil

I had a similar problem once. In my case, I had a sump full of petrol after some major bodywork (new sills). When putting the ECU back in place I managed to chafe the wiring with the result that some of the wires were bare and were shorting out, dumping lots of fuel which worked its way into the sump. The smoke was spectacular.

Changed the oil and fixed the short and it now runs better than ever. Mixing the petrol with the oil must have cleaned out the oil passages quite well.

Good luck!

Finaly it works.
I had to tune AFM, change ECU and fuel pump was conected on "ignition on" position, pin 4 on ECU constantly had 12V, after reconecting fuel pump on "crancing" position and tuning AFM and changing sparks it works fine, and now i can drive my car after 9 months
