Well today my 350 finally laid down. Excellent truck only 257,000 on it. Hit a bump on the highway today. Check engine light came on and lost all power. She’ll run about 30 miles an hour. No loose hoses and getting fuel. Sounds like they do on a cold morning that you didn’t plug it up. But lost a lot of power. She’ll barely crank. And no power at all. Any ideas. Thanks
Ol yea if I get on gas hard enough she’ll blow blue smoke.

 

Did you check the intake system for a possible blockage?
