last night my truck made this funny nosie like it was running on 4 cyns.
the truck was running, I reved the engin and it ran strong. I reved it again and the engin reved strong and than went putt-putt and that strong again.
this morning it started up like normal but the putt- putt noise had not gone..
any Ideas???

thanks

if it runs alright it probably just has as exaust leak. also it could be the cam/lifters (hopefully not).
