Anyone seen code 21 on a non vtec 92 accord? If so, what do you know about that?

 

I'd believe that the codes are a '2' and a '1' , but never seen a code 21.
Louisville is my old stomping grounds, you might want to check the O2 sensors.
If you need help call Scott at Arrons Auto Electric over in Indiana.

 

Thanks "Dude" we also considered that it was 1 & 2 but it displays as one code.

 

NEVERMIND!!! Tech had dislexia and the rear code is 12 not 21 DUH!! Thanks anyway.

 

that lift sensor is probably gone bad. Thats the usual problem for that code.
Salvage yard yourself another EGR valve

 

had clogged passages in the intake, removed the manifold, drilled & cleaned, all good now, Thanks.
