97 tj 2.5, engine code p0171

My jeep keeps throwing the CEL for a p0171. This happens on the freeway in 4th or 5th gear and is usually while going up a hill. The exhaust also has a gassy smell and there is a huge loss of power / gas mileage. So far I've changed out both o2 sensors, injectors, plugs, wires, cap and rotor, and reset the comp by holding the battery wires together. Any ideas?

Also my jeep just turned over 105,000 miles, I'm planning to clean the throttle body today and maybe follow with a new TPS

Check your intake system, maybe its getting too much air.

edit: Oops! didn't realize this was such an old thread

"ΜΟΛΩΝ ΛΑΒΕ" - King Leonidas I, translates to "Come and take them" in response to the Persian king Xerxes who demanded they surrender their weapons.
