I have a code scanner and it came up with the crank position sensor as a soft code that's the only code I get anymore. Once it starts it runs a little rough for 10 or 15 seconds then it smooths right out and runs great it dose not seem to have the power it should but It dose not use excesive amounts of oil (1/2qt in 3k) and no drips on the floor or anything like that. It dose not look like the intake has ever been off.
