I am able to start it again and it idles rough smooth out and again and there is rough idle in park and then (noted:a backfire comming from front of intake/ trottle body) it stalls and dies when put into drive then i cant start it again for 3 to 4 minutes~ my thoughs are Transmission / gear box along with TPS ~any thoughts out there

Sounds like the injectors may be bad or just really dirty. You say that the truck is only used as a plow truck, so I would assume that it sits alot. If you dont add any fuel stabilizer to the tank, the fuel will start to degrade and the will gum up your injectors. One thing you can do is to pull the air cleaner assembly off and look at the injectors while the truck is running. Look at the bottom of the injectors while it is running. The injectors shouldbe spraying fuel with a fan spray of fine mist. If you see any drips of fuel in the this fine mist, that injector is at least dirty or on its way out. I would recommend that you change your fuel filter and then get some fresh fuel and the purchase some Seafoam fuel injector cleaner from your local parts store. Dont mess around with anything else. GET SEAFOAM. If it is in a plastic bottle it is not strong enough to do anything. Seafoam is in a metal can. Dump the seafoam in and run the truck as much as you can. This will help clean out the injectors.

SOURCE: 2001 LINCOLN LS V6 - ROUGH IDLE / SOMETIMES STALLING.

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

Okay I have a 2000 isuzu rodeo v6 4wd and I have been having problems with it since i've had it.I started having slight engine bog and then the car wouldn't even run i replaced the intake manifold gasket...


IT'S CALLED MISFIRE, that get a tuneup yet>?
lacking cash for shop
or cash for tools
how can one fix a misfiring engine,?
no scan tool either.
be impossible.
now DTC errors code stated by you.
there are 50 causes of misfire, at least, i have a list but nah.....
new spark plugs.
see those 3 coil packs, put on new HV wires there
1 by 1, DO NOT MIX THE WIRES UP.
new air filter and fuel filter,? a tuneup, do that first.
is compression at spec. 150 psi or 80? if at 80 the cam belt slipped
that belt is a 60,000 service item are you skipping belt changes.

EGR DTC errors
P1404
1406
1491
1498
which one. each has a different cause. guessing will fail.
fuel pressure
sure.
but no PSI stated
or at key on, idle and at WOT for 1 second. (gunned)
pump pressure is 3 tests NOT one, infact its 6 tests, buy the book.
or more if you do an injector leak down test.

one question really
can you force engine to have full power WOT>
wide open throttle up a hill,? yes..no (right foot aggressive)???
pretend helper cant drive car
tell all things the engine does good./bad/ugly
all things tells use whats up.
hot engine cold, parked and driving flat ground and hills.
all things,
or its going to be expensive guessing.
