needs mounts when it doesnt? i just bought this truck was told it was running rough just because it needed a pcv valve but after buying one it did not help ,, the exsaust is broke off right after the converters also dont know if it might have something to do with that....
when i start the truck it runs rough like needs a tune up it idles fine and shifts in to all gears when i take off from a stop it feels like it needs a motor or tranny mount and it dont need one they are in good shape. but once going it runs and drives fine antell above 45 then acts like has no power and starts shaking real bad any help would be grate thanks wayne
 
start with a full tune up, including new plugs and wires, change fuel filter, air filter etc. clean mass air flow sensor, buy spray material especially for this and follow the instructions on the can. Clean throttle body using special spray cleaner. the if still bad you may need a mechanic to trouble shoot the problem.
 
Start with the basic tune-up items, especially the ignition. If the spark plug wires have never been replaced, you need a new set. Replace them one at a time so you don't get them mixed up.
