help me, codes, misfire and evap
 

98 bazer 4.3 of coarse 4x4 when you first start the car it skips really bad but clears up for the most part after heating up. there is a small leak in intake manifold gasket. I am getting three codes p0300, p0452, p0453 any hep you can provide will be greatly appreciated. I just replaced the injectors thinking that would cure the misfire code.

When was the last time you replaced spark plugs, plug wires, distributor cap and rotor? A random misfire (P0300) is alot of times cured by a simple tune up. Then again, alot of times it is much more serious than that...but always start small :eek:
