just put a 92-95 greddy kit and a d16z6 I/M on a 99 hatch, got everything running but throwing 3 codes for O2, 1, 41,65, what would cause this? still using the factory O2's, there is now no cat though, i have one running into the D/P and one just chilling in the engine bay(to read clean air). ive done this before with no problems. any suggestions?

65 is because you are not running a catalytic converter.

Is your primary O2 plugged in? It should be plugged into your DP to get rid of 1 and 41. What are you using for fuel management?

 

yea 1 is in the DP and one is kinda just hanging in the engine bay, using a vortech fmu, colder plugs is all, only 6 psi.

ive ran no cat on a 96 hatch this exact same way except no turbo and never had a CEL, now im gettting 3?? what else can i check?

 

anyone else?

 

how is tys turbo running? bump!

 

timmy do you think that the wrong o2 is pluggen into the downpipe. i looked in there the other day and they will both reach. i just wasnt sure which one is the #1 o2
