Hey folks, new to posting in this forum, tried to figure it out myself, but I'm stumped.
Scenario:
97 Trep Sport 3.5 with 86K Mi. No mods 'cept chrome Vision 16x7's and an UGLY primered aftermarket hood after running into the "a s s" end of a pickup truck that modded my original hood, radiator and upper rad support (the one on the right is for going...use the one on the left to stop - duh :00000024: ...all fixed). Was code 21 for a while, then stalling, running rough when engine not actually under high load...but when running at 20-55, would surge / buck almost like looking for a gear or something. Anyway had no $$$ for fixing.
Well, my raise came in and there was a retro, so I did what I could. Changed the plugs (Champion Coppers), Wires (Mopar OEM). Fuel filter, gas filter, oil (Mobile 1 10w 30 and Mobile 1 filter like always) and finally a pair of O2 sensors (manifold ones, not the one behind the cat). Pulled the fuse and cleared the codes. Now am only getting 12 and 55. Still having issue with car running a little odd at speed of 40 - 55 MPH just cruising at highway speed. Car feels like it might be looking for a gear or maybe I just ought to change that last O2 sensor...anyone have any ideas?
FYI, change the trans fluid at dealer about 15k mi or 5 months ago. Never did a limp mode thing or anything else.
Thanks for reading.
Anyone have PC questions feel free to ask...its what I do.
