Ive posted about this many times. Wondering what peoples thoughts are on this. Fuel pump/cap/rotor/plugs are all new.

Its a 94 cx with a b16a. The car runs fine when it is cold, but once it is warm, it has a shitty idle, and boggs at mid/full throttle. It is barely driveable at very light throttle

Thoughts?

 

bad O2,faulty plugs/wires,timing off,etc....see if those help

 

If the car only hesitate when fully warm then your best bet is the oxygen sensor. Next is the timing.

 

yeah im going to replace the o2 hopefully this week. But i was wondering what other people thought.

can you tell if a o2 is bad visually, or is it only threw the electronic test?
