Hello everyone
Just recently installed my 4.7 in a 2006 Wrangler. Engine seems to be running ok but LTFT is avg around -13% which is too rich. No check engine lights. I installed 27lb injectors and using the stk pcm. Any suggestions? Also, having a problem with it downshifting out of overdrive. Seems to stay there unless I let off the accelerator and then back on. Weird
Thanks in advance

Re: 4.7 Running Rich
Put correct sized injectors in instead of ones that are way too large?
As for the overdrive issue have you checked the TPS?
