How many miles on it, what does the spark plug look like? Did they do a compression check, if so what was it?

It's a 4.3 L V6 vortec, next step is a compression test, it runs great doesn't flutter when u punch it, it takes off, been talking it maybe the reluctor wheel?

You can check the pickup, should be around 1000 +- 200 ohms, also if you pull it, the magnet should be able to pick up a couple small screws. I doubt it's the ring.

Having a 2nd compression test done, first one was then good but for some reason I'm still getting a po304 code... be honest I'm beginning to think my truck is simply possessed...will chk back...
