Bang! Good Gosh!!!!!!!!!!!!!!!!!!!!!!!!!!

Cranked car and BANG! Smoke came out from under hood and freaked me out. Opened hood and hose from below the intake to the top of the throttlebody was blown off. Car would not run either. It made a sucking air noise when I tried to crank it. Re-attached hose and it ran fine. It did it again just a few minutes ago after heading back to lunch. Blew the hose "clean off". What... Oh well...

Might be... I've been having the hard start problem for several years. After driving and letting it sit for an hour or so it turns over a while before firing up.
Blowing off a hose is a whole new chapter. I don't want to end up like Dale Jr. thia past weekend.

Lean backfire.

Hi, The only thing that would blow the hose off, is a back fire into the inlet manifold. Not a common thing with modern engines. About the only way it could happen, would be if it was very lean at that time. The mixture burns slower when very lean, so that when the inlet valve opens, the still burning mixture ignites the fuel in the manifold, to fire back into the manifold.

Don't know why its lean, could have something to do with the hard starting, when hot.

Harvey.

Not cool

Talked with mechanic today and they are having a hard time with it. He said that it wasn't staying running and was not cranking propperly. My guess is it could be something like crank or cam sensor. I'll have to do some research.

Backfire, hard starts, and poor idle could be the result of burned intake valves. One or more cylinders can't hold compression. Have your mechanic run a compression and a leak down test.

It's very likely your timing belt has slipped a few cogs.
