i bought some ik20s and gapped them to .032, should i have just left them at .04? i still have the runing lean code.. really getting old i think ima just buy the o2 sensor. i know theres two for bank one, what one should i get??, and ima get the mass air flow. even though i get a good read at idle out of the air flow meter

 

Lean codes can be caused by a bad primary o2 sensor or a vac leak. Scan the car and if you dont get a bank 1 code, its most likely a vac leak. The o2's come for a nbo2 and wbo2 and that depends on if your car has VVT or not, just buy it by engine code

 

i get a bank 1 code. no apperent vac leak. ive cme to see that all the parts n my crank case ventilation system.
the y hose from the pressure regulator ro valve cover to the s hose the connects to the three way, and the cuved one that goes in to the filter houseing, which i ordered all 4. im going to hold off on the o2 sensor. i do have 60 days for a sticker out here in mass, im running that gaurantted to pass ****, well c. i obviousy cant drive with the positive crank case hoses out soo.

 

i didnt really like the densos i ran ik22 and i tried to gap them but its pretty hard since they come pre-gapped and its a PITA to get them at the .028 i run the colder NGK bkr7e gapped to .028 have no issues
