idle is about 720 to 850 rpm. its stick shift

ok, checked stlt trim again at idle. now it is st like 10.2 at idle lt is like 5.5 idle was 725.

Anyone???????????? Hello????????

So you've verified that the ECM/PCM has been flashed with the latest program?

yes. what about my stlt trims???

I'm not worried about the fuel trims right now, but that bosch sensor is junk...we get more techs that won't listen us. Use a Denso sensor, and california and non-california are different sensors as well.

bosch sensors are good and as good as denso.

Your fuel trims look good, so the engine computer is not having to add or remove a lot of fuel due to the a/f reading.

Is there a certain rpm where the CEL turns on?

not that i noticed. i changed the air fuel sensor so will see what happens, so far so good

well it has been at least 3 weeks and 600 plus miles since i changed the front air fuel sensor and i have NOT got a check engine light back yet. I am sure since I am posting this it will pop back on now :eek: but I think this fixed the problem. :D
