Apologies, new to the forum here. If this is posted in the incorrect area, just let me know & point me in the right direction! Looking for some help with a new to me Wrangler.
Have a 2004, 4.0 TJ automatic & recently received a 0132 (02 sensor, bank 1 sensor 1) check engine light. At the time of the light the Jeep ran like it had a misfire. I figured with the amount of miles (124K) I better give it a quick tune up so I replaced spark plugs with NGK 3459 & coil pack with Walker 9212040 (921-2040), cleaned the throttle body, installed TPS & MAP Sensor with Walkers (All from Rock Auto), cleared the code, ran & the 0132 light came back. I checked spark and all cylinders were receiving strong spark.
I moved onto the injectors. Checking the wiring behind the valve cover along with the connection plugs & didn't observe anything abnormal. I isolated one at a time by pulling the connection plugs & when I pulled injector #6 the engine didn't run any different. I didn't have a noid light at the time so I pulled all the injectors, tested individually by applying 12V & found #6 not cycling correctly. I cleaned them, blew them out and #6 now seemed fine so I re installed. Once started, there was an odd tick sound that was not there prior, along with the same 0132 engine light so I replaced all 6 with TRQ's off amazon. ($130.00 for the set). No more tick sound but still have the 0132 light along with same misfire / erratic idle. I purchased a noid test light and they all receive signal / flash as intended.
I was in town so I picked up an 02 sensor (Walker 350-34592), installed & the 0132 light went away. Ran it up and down the road & got another check engine light. This time 0175 (system too lean). WTF.... I checked everything over again, ran a fuel pressure test on the fuel rail and was getting 39psi with key on & 48psi with engine running. Turn the engine off & it held 48psi without issue....
Figured what the heck, cleared the lights again, ran up and down the road & it would up shift & downshift out of overdrive non stop and seemed more gutless then normal. (Assuming because its not happy & misfiring) either way, it threw a different engine light. This time 0152 (bank 2 sensor 1). I pulled over, cleared the light, flipped the over drive switch & oddly enough, ran further then I have before & it never threw an engine light.... I'm not sure if that's because its happier at high RPM? or what but im stuck here and needing some suggestions.
Am i missing anything here?
