It is the 4.7L engine 4x4 SLT model. Never had engine trouble or symptoms before. Today it hesitated starting when filling up, I got home ran it awhile shut it down and started it a few times. Check engine light came on, hooked up reader and read 2 codes, 1st was cylinder #2 misfire and the second was EVAP emissions fault. I noticed more white smoke coming from the tailpipe and then from over the hood. Popped the hood saw smoke coming from the back of the motor drivers side. Had my wife continue to try and restart it as it will not start now at all and only smoke from this spot in the rear drivers side of the engine. Please help......
Well,you may have an oil leak,but #2 missfire may mean a few things.
Pull #2 spark plug and see what's up.
be sure you are getting spark to #2.
Check for a vacuum leak,also.
Testimonial: "Thanks, I now replaced the #2 spark plug and coil pack, no changes, now getting multiple/random misfire code?"
SOURCE: check engine light comes on and car idle's and
I found this; if it helps.
The injectors need to be cleaned, if an engine is experiencing any of the classic symptoms of dirty injectors, such as lean misfire, rough idle, hesitation and stumbling on light acceleration, a loss of power, and higher hydrocarbon (HC) and carbon monoxide (CO) emissions.
Lean misfire may also trigger a misfire code and turn on the Check Engine light on 1996 and newer vehicles with OBD II systems. The code often will be a P0300 random misfire code, or you may find one or more misfire codes for individual cylinders, depending on which injectors are most affected.

Hope this helps
SOURCE: Check engine light
A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.
The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

TRY REPLACING THE CRANKSHAFT POSITION SENSOR..HAVE SEEN THESE CAUSE MISFIRES AND LOW VOLTAGE DTCS AS PCM THINKS VEHICLE IS NOT RUNNING..ALTERNATOR MAY NOT BE PUTTING OUT PROPERLY

when u press the gas pedal to go this opens the throttle valve, the idle speed of your engine is computer controlled, this is done by the ISC (idle speed control) airbypass valve, these parts get full of gunk and then get a stalling problem at or near idle, clean them by doing the following, if u don't understand the instructions seek help from your friend.
, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Check for
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.

ENGINE MISFIRE
There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
