The engine runs lean only due to faulty fuel system. The reason can be clogged fuel filter or fuel pump. For further assistance you can refer:

SOURCE: Ford Escape 3L 2002 Rough idle

generally, when the engine is washed, water gets trapped behind the spark unit and stays there, creating a shorting path for spark plug current. best to dis-mount the spark unit (follow plug wires back to source) and dry and clean it thoroughly.

SOURCE: chrysler 3.3 vin r v6 mini van, starts then dies

Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.

The other option is: Get a new ECM from the dealer, They will program if ask for that.

NOTE:::::: Other way is . Put the body control module with the computer from the same car.

OK... I hope this work for yours.
If NOT letme know I can look for more information.
Thank you.

I recommend getting a repair manual from an auto store for your vehicle. They run $15 to $20. It will tell you exactly how to do everything you asked and also give you the values that should be expected. Hope this helps.

What would cause a rough idle when cold and at idle but runs great once warm

I'd be pulling the spark plugs and checking for condition, gap, fouling, etc.

Motor runs and starts fine when cold then after a couple of miles it drops one or two cylinders

drops, (you saw spark gone?)
gaps? what gap, spark plugs? no new cap? with real brands, not clone junk?
Finish the tuneup, then set the spark gap to spec and do not use $20 expensive, surface fire spark plugs, use regular NGK J sparks.
this car is NOT HEI ! it is not.
if spark, is now perfect, and the spark tips dont turn black running. do they? then it may be running lean.
hot running needs this:
good engine compression,
not stuck open EGR main valve. (clean it)
good spark timed to spec. using quality parts not clone junk.
then suspect fueling last, if above is good ,its a fueling issues, (the cat is ok, if melted it would clog engine hot or cold) forget CAT.
the coolant needs to hold at 180f or more (195f is nice) and not drop.
the 02 sensors must work and no exhaust leaks near it. allowed.
ECT shows 180F. (about 300 ohms hot< DMM meter check.s)
fuel pressure at spec. near 30?

You either have a huge engine vacuum leak or the fuel pressure is low, this gives the lean codes you have for bank 1 and 2 of the engine, have these two items checked out.

My ford escape stalled on me while driving i had just install a new alternator 1 month ago because it did the same thing

Check your coils on the spark plug, also check your EGR valve and Idle air control valve. Mine did the same thing and I had to replace the IAC, and EGR valve and replace to coils on the spark plugs

1989 for tempo starts fine but after idling for a few minutes will quit. Will stall when you pull up to a stop sign. Have to keep the engine revved up to keep it running. The check engine light comes on...


its time for new fuel filter, new fuel injectors, spark plugs, spark plug wires, cap and rotor. the engine in the tempo is a good one and if you take care of it that car should last quite a while longer..

You have a vacuum leak. Did you use new intake manifold gaskets and torque the bolts according to the spec? Did you get all of the vacuum lines back on in the right places?

2003 Ford Ranger starts hard.

That sounds like it could be one of many things. Have you ever given the truck a tune up? I suggest the following things first.

New Air Filter
New Spark Plugs
New Plug Wires
Oil Change (and filter)

These are the basic necessities of an engine. Having a dirty air filter, or plugs that are firing weak can surely cause this problem. Try giving the truck a good old tune up and see how it starts then.
