ok, i have a 02 f4i, it had a jardene slipon on it and had a whole for the O2 sensor and i just got a scorpion high rise for it and theres no hole for the sensor so i tried running it with the senson just sitting outside the pipe and it ran like ****, smoked a lot and was just running VERY rich, so i tried just unplugging it and it still didnt change the effects...any way i can re-wire it so it tells the computer its there but it really isnt?

 

you need to get an O2 simulator or you can cut a hole and weld a bung on there for the sensor to plug into.

 

ditto. worked for me too

 

JUST TO KEEP YOU ALL INFORMED


1. Installed TFI and added more fuel to the low end and Accelerator pump
2. Changed the Spark Plugs to new ones (19K without changing the stock)
3. Did the 520 sprocket conversion -1 / +2


Results: The low end bog was reduced by 75%


its still a little noticiable but improved.

 

i have the same prob, and have done pretty much the same, -1+2 sprockets, but do you still notice the off idle snatchyness?, the only way that you are gonna get rid of that and smooth the throttle response is get the PCIII...

peace
