Hello! I have a 1998 4.0ohv 4wd. Recently I got the p1309 code and also the p0171,p074 bank 1 and 2 lean codes. I proceed to change out the Cam Position Sensor and syncro. I did them both correctly exactly by the book. Made sure to put the engine at top dead center ect. I reset the computer ( left battery unhooked for few hours ) and started her right up. It began to relearn itself but started running rough and sputtery. I maybe thought it could be the
TPS ( throttle position sensor )
MAF ( Mass air flow )
IAC ( idle air control )
and air temp gauge.

I ordered a new MAF and TPS since i found a good deal on amazon. I clean the temp gauge and IAC. After another reset it developed this problem.

from 0mph full throttle no acceleration at all. 0. half throttle was quick and fast and sounded healthy. I proceeded to do some research on the fourms and found a issue could be ground wires and PCM ( power control module ,the ecu/computer ) I checked all my grounds and even took off my coil pack and cleaned the grounds under the coil pack and threw it back on. I even checked the fuel filter and got sprayed right in the ear -_- even though i relived the pressure! Right now its doing another computer reset.

My question to you dear kind folks is this. What the hell could it possibility be!?

ive checked spark plugs, cleaned air filter, checked fuel filter, checked all vacuum lines, brand new MAF,TPS, cleaned IAC and temp gauge. I need help please! Im lost and dont know what to do. thank you all so much!
