'02 GT Coupe PO171 Code

[gtonut1]

I am new here, thanks for the add.
My GP stalled and died, I had good fuel pressure and it would run above 2000 RPM. Tried to make a run for home but went 2 miles then only WOT. Had it towed home and scanned got MAF was out of limits. Changed that and it fired right up, 2 days later I get Lean bank 1 PO171. Cleared it and it came back in 10 miles. No leaks detected with carb cleaner and it runs very well, no problems at all. Could be O'2 but want some in out as to what else it might be.
Thank you.

I'd smoke test it to see a vacuum leak.

Lots of time the carb/brake cleaner trick won't find everything.

Thanks I will see if I can do that myself or have it done.
