I've been having some problems lately with my ranger it idles really low sometimes when i push in the clutch and let go of the gas and sometimes it even shuts off if i don't give it gas fast enough.. Also the check engine light has been coming on while driving normal then just goes off... So i got the codes today, It gave me a code 33,35,53,12 and 13.. I found that a 33 is throttle positioner sensor noisy/harsh on line, 35 egr valve circuit above maximum voltage, 53 throttle position circuit above maximum voltage, 12 idle control fault and 13 dc motor did not move.. but i have no idea on how to fix these.. and Ive also noticed the truck not having too much power but then again im not sure if that's normal for a 2.3 ranger this being my first but it does feel really slow and i feel like its sucking up alot more gas than a little 4 cyl should be... any idea's would be really appreciated thanks..
