i have a 91 sedan with jdm b16. need help when the car is cold runs great but when the car gets to runing temp. the car boggs. thanx for any help.

 

what ecu you running? How many o2's you using?

 

Have you done a tune up with fuel filter yet. Does it go fast when cold and no bogging right. The ECT sensor is a good piece of insurance, change it anyways. More help here if you need it, have you cleaned the throttle body and IACV???? Do that before changing the plugs.

 

i change my o2 sensor i am usind one. i have no check engien light. yeah i change the fuel filter. the car boggs when is on runing temp. i will try what u toll me duane_in_japan thanx guys i hoppe it works
