i have a 97 civic lx sohc 1.6L. i have done basic tune up to it. plugs, wires, oil change and last thing was ignition timing. i have adj. to the red mark viewed from correct angle. shortly after i got engine code for iac (autozone) sensing to much or to little air. i can clear it but want to fix issue. help...

 

o also new alternator

 

engine code P0505

 

Idle air control: P0505 so I would recommend cleaning your IACV you're thinking of IAT

 

If you clear the code does it come back?

 

i haven't actually cleared the code yet. i figured i would try to figure out what causes the issue first

 

^^^guess you didn't see my post.... clean it then clear the code
