2004 Buick Rendezvous 6 cyl All Wheel Drive Automatic 147, 00 miles
Hello, about last month my truck slowly started with idle problems it would hold an idle at about 3 rpms, so took it to mechanic and did obd. Too many codes came up so we tried changing by codes. Finally replaced main computer. Mass flow sensor. Tp sensor ect. After changing main computer, I suddenly now have a battery light that wont go off and I failed inspection for emissions not ready. I did another obd after replacing all those parts and I keep getting these codes. Po641 (5) volt reference 1 circuit, po122 tp or app sensor 1 circuit short or low, po453 evap pressure sensor signal high, p1122 tp circuit low voltage, p1819 internal mode no start, wrong range, help please I am unemployed and have 2 small children I ve already put 1000 of parts I probably did not need to change. I also changed alternator.
