As title says. Code p0148 no power at high rpms pops out the exhaust. It did throw a crank pos sensor. Put in a known good one that code stopped. Heres some things i have done. I ran the valve lash just for the hell of it. They were a little loose not bad there at spec now.
Changed fca with known good one. Installed railplug. Crank pos sensor
I hooked up my rail gauge and when it first starts it spikes up to like 15k. Then slowly drops to around 8k and stays. Under full throttle it will hit 10k. Then when you let off it will spike to 12k. But it idles at 8 k constant. In neutral if you rev it it will hit 15k but not when driving
The owner of the truck replaced the lp with a stock in tank. And put new fuel filter and air filter.
Truck is bone stock besides strait pipe.
What are some thoughts of what could cause this
