Need some tech ?'s answered.
I had a diagnostic tool hooked up tonight and it's telling me my longterm fuel trim #'s are low. They're supposed to be 128 and they're 117 and 120. Is this a problem? I'm still trying to figure out my hard starting issue. BTW, there were no codes.

With those #'s , your PCM is well "in control" of the fuel trim. However, those BLM's below 128 mean the computer is subtracting fuel on the long term fuel trim. The O'2 are reporting a rich condition therefore the removal of fuel. The hard starting (when warm) may be leaking injector(s).
