Hi Guys,
The project got pushed aside for a fews weeks and ended up running into 2 years, finally getting back to it and hoping to have the car out for some events before the end of the summer.
I got hold of a 4-branch cup-car exhaust manifold and have fitted this to the car, the car is starting fine and running, but it's over-fueling massively (a lot of backfiring and odd spit of flame from the exhaust). There's no cat converter in the system and only a place for one lambda sensor in the exhaust. Im not sure the sensors alone would cause the car to run that poorly? but maybe im underestimating the effect they have. Has anyone come across similar issues before? I'm wondering should I be looking towards injectors.
Any help greatly appreciated.
