Thread: Puffing Black Smoke

When revving the car to about 3000 rpm black smoke comes out of the exhaust and stop(this revving hard to 3000 rpm) , if continue revving higher then release throttle black smoke comes out again. Can anyone help me.

I checked the tps, the maf, the coolant tempreture sensor and everything seems ok.

Blesss

bad program in ECU(chips)if its a calum, try reburning them or just a bad ECU

X2 or incorrect fuel pressure at the f regulator, you need a tune

thinks he gets the same result with a stock ecu as well

afr is also 11.xx to 1

peace

So the fuel pressure might need to get adjusted to get a better AFR

Found out that the knock sensor is bad. So the car is running in limp mode. That is why its running so rich.

What ecu do u have?

delete that out of the program and the o2 sensor

why? isn't the knock sensor there to prevent damage to the engine?

so what time tomorrow you picking up that one from me?

why didnt the initial scan you did, didnt give you the code?

peace
