vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

I would check the injector. Pull the plug and check for corrosion. Use on ohm meter to check the injector. The resistance should be 11 to 15 ohms. Check it against another injector. they should be close. You can also check the injector plug. best to use is a noid light, but you can use the meter. set it to dc volts to check. the numbers should jump everytime it fires. since you got a 300 and 301 misfire it tells me that you have an intermitant misfire in cylinder 1. The other sensors are still good don't replace them. The coil is still good, because when it starts to go, it will have misfires on all cylinders or will not work at all. The crank sensor is the one that detects the misfire, again don't replace it because it's not bad, it's just doing it's job. If the injector and harness check out good then I would start check the cylinder for compression and mechanical problems

did you check the coil it may be bad. for # 1 cylinder. if you can, just replace them all. then you will know everything is ok! but change #1 coil first to find out. try putting some injector cleaner in the tank, or swapping the injector from the #1 cylinder to the #2 and see if the code follows it and let us know.

Tips for a great answer:

Trouble Code Conditions:
Engine runtime 3 seconds, engine speed change under 1200 rpm, and the PCM detected a misfire condition present in one cylinder during the 200 (Catalyst) or 1000 revolution (Emission) test range.Note: If the misfire is severe, the MIL will flash on/off on the 1st trip!
