No I sure can't count how many counts it's at.

ok gotcha, thanks.

 

Ok the P0300 was the injectors. I took it to the shop and had new exhaust put on it, crank relearn, and camshaft retard set. So now Ive got it to where I can drive it and I get a P0172 and 175. The shop said my PCM temp sensor was reading -40 and the 350 vortecs had two sensors, but my 2000 blazer did not and I cannot find where I'd wire one in at on the PCM. I replaced the temp sensor and nothing changed. What can I do???

 

I hope this doesn't sound stupid. But maybe the temp sensor for the intake? If it's telling the pcm that the incoming air is WAY COLD, it's going to run WAY RICH. Kudos on the swap.
