[QUOTE="tonyt, post: 94029, member: 405"] nope. ran a temp jumper wire from pin 72 to the wire on the o2 according to the drawing. no difference. still reading a flat 450mv. the computer NEVER goes closed loop. does the computer need to see o2 to go closed loop? or does it start looking at o2 AFTER it goes closed loop? what conditions are required for the system to go closed loop? double re-checked all the grounds. harness is grounded to back of head. engine is grounded to battery, battery is grounded to body. IAT is good. ****, this is pissing me off. [/QUOTE]
