I made a mistake. I installed a catch can with a check vave on the wrong side.
yea...
I drove around about 50 miles before I learned what I did: I heard a hissing noise coming from the engine, so i disconeected what I installed, and from there I figured out I might have done something pretty dumb.

The truck does seem to run fine and as usual; the only thing I've noticed is that sometimes the truck doesnt start up smoothly as it had. Sometimes it struggles in the begining (like a bad battery would cause) and some times it struggles right at the end before turning over, and the other 50% of the time, no struggle...

Please keep the advice to just what i hould do on the truck

Thanks.

 

Any ideas at all would be appreciated
