2001 Accent-P1128 error code
 

Well, all the old posts seem to be mismatched. Anyhow, I'm about
to wash my hands of this car, not my problem. Brief recap-

Car was neglected until the check engine light came on and it
became almost undrivable in Dec 07.

I changed the plugs and wires, cleaned the MAF and changed the
oil. Car drove OK, check engine light came on after several days
with error about the converter.

Car was driven down to Fl and back without difficulty, and since
then.

Owner is now finding he cannot get NYS inspection because CEL is on.

Error was "misfire" on cyl 1 and 4. I notice these are on the
same coil.

Error is now stated "P1128" and something about Fuel Air
metering and lean condition under partial load.

Error previously was something to do with the MAF along with the
misfire.

Sorry about the vagueness, I'm getting this from the owner and
it's rather garbled. My preference would be that he take it
somewhere and stop bothering me. I promised I would ask and see
if anybody could point me in the right direction ("That's a bad
MAF, 99% sure!") as a last ditch effort.

I thank you all for your time and for any advice.

Re: 2001 Accent-P1128 error code
 

The number one cause for this code is the mass air flow sensor, but another
common problem I've seen is a hole sucked into the PCV hose. That, too,
can cause a lean code.

Combined with a P0301 (or any other misfire code), however, suggests that
there could also be a low fuel pressure issue.
