Question about 1990 Oldsmobile Cutlass Ciera
Car run fine 4 half hour then stubles and stalls fuel pres is 48 lbs code 12 comes up i think ecm or ign mod or crank sensor any ideas thanks in advance john
Check your fuel pressure regulator. Make sure you have a good vacuum to it and it is not leaking. 48 psi is a bit much and once it warms up will cause the vehicle to stumble and stall. Code 12 is a normal system.
Hope this helps.
