Mother F'ing 09-01 and 10-01 codes.
 

So just for the hell of it I replaced my PCV valve, cleaned the IACV, unplugged every vacuum tube, checked the brand new o2 sensors, etc etc etc... for about the 4th time now.

Still getting code 09-01 and 10-01.
30% of the time I get a rough idle, and sputtering while cruising in gear.
It will also stall out at idle every now and then.
Not to mention about 18.5 MPG.

I've replaced BOTH sensors 3 times now.
I'm about to hard wire them into the damn ECU or some shiz.....

Poor idle: check and ensure your intake manifold gasket on the front (just behind your injectors) has not been sucked in. A plugged/faultyPCV valve can cause the rubber gasket to be sucked in. It'll cause poor idle and acceleration. To test - grab a can of WD-40 and spray along the rubber gasket, both in front and behind it. If it revs up, you got a problem. You will also hear a strong sucking sound - but its hard to tell if you've had it a while.

BTW - I think the fault heat sensors are not causing poor idle - do you have a good OBDII reader you can plug in and drive?

have u seafoam'd??? i say that might help the rough idle alil...
