Ok so I have a 2000 GT that has had a p0300 code for a while. It's only really noticeable with the A/C on, though it does die occasionally when coming to a stop. So I hooked up the code reader and here's what I've got...
At idle:
SHRTFT is within acceptable ranges (-6 to +1)
LONGFT1 is +7
LONGFT2 is +16.4
Output voltage for O2B1S1 and O2B2S1 fluctuates between about .1 and .8
Output voltage for O2B1S2 is relatively steady between .700 and .765, while O2B2S2 is between .635 and .660
At 2,500 RPM:
SHRTFT is still within acceptable ranges (close to zero)
LONGFT1 is between 10 and 11
LONGFT2 is 13.3
Output voltage for O2B1S1 and O2B2S1 fluctuates between .1 and .9
Output voltage for O2B1S2 fluctuates between .1 and .8 and O2B2S2 from .2 to .6
Additionally:
Vacuum reading is healthy (17in at idle and I'm at 5280 ft elevation)
No other codes are ever thrown
I have cleaned MAF, replaced plugs, new fuel pump, replaced EGR valve, cleaned IAC valve, cleaned TB, and some other stuff I'm probably forgetting...
Please help... Any input would be appreciated!! Thanks!
