Trouble Code 44???

wow i been so busy working i just now noticed all the changes to the sight,and i have to say it looks great.

Now the car trouble im having.My cars been running like sh@t and the idles all messed up it seems and sometimes it clears up but the SES lighjt comes on the the car runs real rough and almost stalls.Sometimes the car didnt wanna start too and i replaced the Fuel pump relay cause i was getting a code 54 and code 44,so that eliminated the starting problem.But it still runs like sh@t and i have the idle problem and stalling problem,and still the code 44.I checked and found no vacuum leaks at all.The oxygen sensor is pretty new,but its not the best from what i know so maybe its already shot.Im wondering if anyone has any ideas what can be causing my code 44 and car problem.All i know is the code stands for lean exhaust or oxygen sensor lean.Can i test my 02 sensor somehow or does anyone have any ideas? Thanks guys,Al in NJ

well If you had a scan tool you would know but, I am sure you don't have one or you would not be here there really is not much that can be wrong with that circuit unless you have an open some where in the circuit making the ecm think it is lean. a sc could most defenetly put a cheeper o2 out real quick. I had 2 napa o2 sensors go out with in 2 weeks once. and that was on my stock 305.

Disconnect the electrical connector under the MAF and see if the idle problem clears up.
