Truck is a 90 chevy suburban with 350 w/th400. Before the rebuild the only code i ever got was the 32. now i have a code 33 which according to this sight http://chevythunder.com/fuel%20injec...0pg%20a.htm#32 Means i have a bad MAP sensor. Just dosnt seam like it would go bad by sitting on the work bench. I'll try to find specs of the cam i put in there but im pretty sure that it is a very computer freindly cam, infact i think i could have even gone up two more steps and still had a happy computer. Anyone have any other tips for me about code 33?
