I have a 2000 gpgt with cali emissions i currently have checked for vaccum leaks visible and with carb cleaner changed front o2 sensor due to broken wire and fuel filter cause i recently did a full tune up. in which all made light go out for a while came back on and now its a hard code i have some freeze frane data

Short Term Fuel Trim -2.35 % Bank 1 Long Term Fuel Trim 16.39% Bank 1 Map 1.03 inches in mercury

any ideas will be geatly apriciated

Try unplugging the MAF and see what happens.

maf reading is 1.14v with the freeze frame data

The MAF is a frequency signal so freeze frame voltage data only tells 1/2 the story. The other reasons behind that code are things you already checked into even though vacuum leaks are very tricky to find and can sometimes be missed even after multiple attempt to look for them, but unplugging the MAF takes 3 seconds and is a good way to rule out a dirty/faulty reason behind that code.

Document ID: 561061 in the service manual ^^^^^ is p0171 specific and could help with some other checks.

what should i be looking for

Just go to the top of this page on the right side of the header, click on service manual, then "Find a document...." and paste that ID number in there and it will run you through a whole list of checks. I'd still start by unplugging the MAF and see if the lean condition goes away, since that's the easiest place to start.
