new guy and bout to give up on this truck
Ok I got a 91 ford ranger 5 speed with the 2.3.. I've replaced ecm, tps, spark plugs, wires, fuel filter, pcv valve, both coil packs and that's it I think.. but when I got the truck it was getin 25 mpg and runnin fine then all the sudden it got 18 mpg and runnin like crap. It hesitates and when you hold the throttle a certain way it sputers. Now when I unplug the tps it runs fine just idles high but still didn't change the mpg to much.. what could the problem be..
