Mb2 bogging down, now fixed!

[skitzma8]

I am still chasing the problem that's making my mb2 hesitate and bog down at 4000 to 6500rpm, but when it passes 6500rpm it gives a last little push to the red line, the car is fine when I'm driving at low speeds but I still have to feather the accelerator peddle to stop it bogging down. Today I took the standard air filter off and put a cone one on. and it seemed to run slightly better but still bogging down, and I'm still getting p0171 system too lean. I really need this sorting out asap

When the EML is on have you tried reading it for a code?

she only keeps throwing the same code P0171 system too lean bank 1

I really am starting to lose it with this car I suffer with some mental health issues, and I've just smashed up things in my house because of this s**t car!

Too lean to me says it's not getting enough fuel, is that right @phill1975?

[phill1975]

To lean is to much oxygen in the system so yeah not enough fuel

When you say injectors and cleaned out throttle body how much did you clean throttle body out

[phill1975]

And you say you have changed O2 sensors did you use genuine ones or aftermarket

I swapped out the injectors with ones I know that work, and I took the throttle body out the car, and used more or less a whole can of carb cleaner, a lot of black stuff came out but didn't improve it one bit. I also used genuine denso O2 sensors I know aftermarket ones are no good, could be fuel pump but I don't like messing about with that stuff, I think it's time to go to a garage

[skitzma8]

Went garage today for a replacement dizzy... Hasn't done nothing more cash wasted!

[phill1975]

Have you checked the plugs since or was it doing it before you changed any parts
