1998 GMC K1500 350 engine, number 1 and number 8 cylinders not firing any ideas?
1998 GMC K1500 350 engine, number 1 and number 8 cylinders not firing any ideas? Truck is in local repair shop, I know newer vehicles are not easy to diagnosis but here is what they have as possible cause, crank sensor or fuel metering body. Truck will start, running very rough, have to use gas and brake to drive. Wondering if anyone has had this problem.
