Ok... i got rid of the 1132 and even passed smog on Monday...yesterday the light blinked a couple of times so i stopped by a friends and he hooked up the machine and said it was throwing code 0172.......Rich or lean at bank 1... i have cleaned the MAF, checked for vacuum leaks and cleaned the throttle body.I have even tried the C foam, and i still have a bit of hesitation... i am out of things i need to do.. any help would be appreciated!! thanks.

P0172 isnt rich or lean bank 1, it is rich (adaptive limit reached) on bank 1. As noted above looking at LTFT on both banks will help to isolate the problem. If bank 2 is normal and bank 1 is at, say, -20+%, you probably have a leaking injector. If both banks have high negative trims, check fuel pressure and MAF.
