2001 SL2
Default Re: Saturn SL2 High RPM's when switching gears

I have 6 codes for my saturn sl2 2001
They are: P0404 P0405 P0403
C0037 (left front wheel speed sensor circuit low... I just had the bearing replaced in the front left wheel?)

The problem is that I have higher than normal rev when I start the car and at some point in my commute I notice it revving when shifting. When coming to a stop light, if I coast it in neutral for several seconds it still will not reduce the idle speed until sitting stationary for 3-6 seconds.

I have checked for leaks, cleaned TB,IAC, EGR, and had transmission tested. Should I check the ECTS Sensor? Thiking that if the temp is off it will rev at wrong times to heat up the engine.What should I check before I replace the EGR valve as I do not know how to test it?

I cleaned it and pushed in that little valve (It didnt move much but it did like 4cm)
