90MPH+ check engine??
if im goin about 85, 90 miles an hour and hit the gas to go a lil more it sounds literally like popcorn coming from the engine, i origanally thought it was a bad cat that had some crap in it because on initial startup you can hear a little clatter, anyone have a similar problem or know if it is justmy cat thats makin the noise....

RE: 90MPH+ check engine??
Are you driving a quad cab? They have a 97mph speed limiter, are you bumping up against it? It always sounds horrendous, especially the first time you bump up against it.
It's also possible that you have the infamous belly pan gasket leak, especially if you're consuming oil. With the engine off, remove your air intake, and flip open the throttle body blades - if you see oil coating the inside of the intake manifold you probably blew the gasket. At that point you'll have to decide whether you want to replace the gasket, or go ahead and buy/install a M1-2bbl intake manifold.
