I have changed everything i can think of in my car.
Plugs, wires, dizzy oil change , flush all fluids, fuel filter, o2 sensors,pcv valve, running 91 oct gas, even changed the ecu, and the car is STILL running rich !
Its been running rich since I dont know when.
36L of gas will only get me MAX 400 km.
Can anyone help or have any experience with this problem?
I am running a b16a with a pr3 ecu
No mod parts except a short ram intake.


Edit: What are all the reasons for "running" rich
Sorry for typo

I have a very strong gas smell at the exhaust.
And when the car is warmed up, when i idle, it would idle at 700, jump to 900 go back to 700 and then it would stay at 700rpm.
It only does this once or twice everytime i idle maybe at a red light
Any help would be great


Thanks

 

this a long shot but test your throttle positioning sensor (TPS) or map sensor

 

do you have a catalytic converter?
honda engines are pretty smelly without a cat converter.
and 11 km per gall (27 miles per gallon) is kinda bad, check your tire pressure, and alignment

 

thanks for quick reply.
I will try it out !

 

try to check for the map sensor, is the idle shaky?

 

Yes the idle is shaky T_T
I am still trying to figure out the problem.
=[

 

I'd be checking these.

 

+ 100

Bad fuel consumption, irregular idle, & a miscalibrated TPS is almost a trio that lives well together.
