Well I have read all the answers you all have given on this problem. Going to try and clean MASS Air with brake clean tomorrow. But my trucks symptoms are, Ruff idle first start in the morning. (have to gas it a little to get out of that) When i first press the throttle it seems like it is a little hesitant and as more fuel is added it clears up. I have OHM'ed all the O2's and they all read 14. reg is 11 to 16. So what do you guys think???
