4.7 Running Rich

Post by bschimmel »

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

Put correct sized injectors in instead of ones that are way too large?

As for the overdrive issue have you checked the TPS?
