fouled out 2 brand new plugs, 1&2, my air fuel ratio meter says normal, no codes, tps set a .42, disconnected the maf and ecm wire connected the ecm wire up no differance, put timing light on with everything hooked up running about 32 btdc, put in bypass mode runs 12. new o2 sensor(a/c delco), tapped on MAF no miss or anything. no codes. what else would make timing so far advanced, or is that normal? could that be the problem with it running rich? hooked up a snap-on scan tooleverything looks ok, except maf reading with engine-off key-on had 120----, tool said should be between 3-9
p.s. the car wouldn't run with the coolant sensor disconnected.
