Go to www.hmaservice.com and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals,
service bulletins, illustrations, etc. To diagnose a 2000 or 2001 1.5L Accent Diagnostic Trouble Code (DTC) P1128 (FUEL SYSTEM LEAN -- PART LOAD), check the following:
  • Check the intake system for air leaks.
  • Check that the Mass Air Flow (MAF) Sensor (P/N 28164-22610) operation meets the specifications listed below. If the MAF sensor output is significantly lower than the reference value (10% or more), then replace the MAF sensor.

Ive got a focus st170 and about 4000 revs it seems to missfire


  If you mean in neural it misses this is normal. It has a rev limiter to save the engine. You are bouncing it off the chip at 4000 rpm.

Reduced power below 4000 RPM


The main relay also controls the transmission and will cause an intermittent interruption of power and indicates its going bad. about a $60.00 replacement cost. the relay is located under left side of dash.
