3 amigos and a question

[steach]

I have searched the 3 amigos thread and there is lots of good information. I checked for diagnostic codes and had two. a PO307 and a P1590. What is the P1590 related to? Back to the 3 amigos, I tried spraying them off with carb cleaner and a pressure washer as discussed in the thread. Still there. Next, I planned to pull the wheels and pull the ABS sensors and clean them. I looked at my Rave CD and it says not to remove them as the hub should be renewed with the sensors. Is this true? or can they in fact be removed once the wheel is off and the truck supported? I have read how to clean them once out and want to try that before moving on to the shuttle valve. Ideas?
Blinded by the lights in GA!

IIRC you can remove the ABS sensors with out taking the wheels off. They just unscrew from the back side (I may be wrong)

P0307 is miss fire cylinder 7

P1590 Rough Road Signal Implausible

I will look at them again today and see if they unscrew. Thanks for the code reads.

Just so you know, these codes normally mean a dirty MAF... might want to clean it.

Thanks for advice on the MAF. I took the wheels off and cleaned a little rust off the ABS sensors but the lights are still on. What would you look at next?
