Question about 1998 GMC Sierra
Ok so a few issues here, i got a small trace of water in the distributor cap so i dyed it and then put it all back in place, truck ran good for about 20 min then started to want to die stall out, its a pain to get started, and now on top of that the light to let you know what gear flickers on and off and hard to tell what gear im in, no power when you out the foot down,engine light is on throwing code p0151 o2 senser 1 bank 2
Replace the sensor as it is not controlling the correct fuel ratio. Recheck for more moisture in the cap as the water is in the distributor and will evaporate up and affect the spark process.

Sounds like the cpi injector assembly. The fuel pressure regulator may be leaking. Or the poppet valves on the injectors may be sticking or shot. I replaced almost every part on my truck and that is what it ended up being the whole time. It's a common problem on these models. Hope this helped

Smell of the oil,to see if the fuel injector(spider)is leaking into the crank case,if so,the intake will have to be removed to repair the problem,oh,and change the oil.
