Re: Need help - Rough running Ranger
Josh is right, the rattles are pretty normal, and are usually something to do with a cracked or loose heat shield.
The TPS, if that is the problem is easy to change, but is real sensitive to adjustments. You have to back probe the yellow wire at the connector and connect a multimeter to it. You have to unhook the throttle cable, back off the air idle screw untill it doesnt touch the throttle arm (which in turn closes the butterfly), then adjust the TPS to .528 volts. Lock down the TPS, making sure it reains at .528, then turn the air idle screw while watching the multimeter until it reads .660 on 06 and 08s, and .710 on 05 and 07s. Then hook the throttle cable back up, being sure it has just enough slack that it doesnt pull on the throttle.
The bad news is sometimes those symptoms are caused by a bad Tbap sensor or damaged wiring to the Tbap. Both parts can cause simlar symptoms. Be sure to check the iwres right at the Tbap connector, they can break inside the plastic, so you have to lightly pull on them to see if they stretch.
