INTAKE MANIFOLD RUNNER CONTROL
I have a 2002 f-150 with a 4.2 liter v6 engine.
my check engine light has been on for some time and occasionally at highway speeds the truck will start bucking like it is starving for fuel.
my local dealer first told me it was the fuel pump so i have a new $400.00 pump in my truck. when that did not fix my problem i took it back to my local dealer and now they are telling me that it needs to have the
imrc replaced and that as part of a tsb 07-1617 i need to replace the lower intake manifold also at $1065.00. i would like to verify this, as i really need my truck fixed. it also is having a problem starting and they explained that as the number 6 injector being stuck open and bleeding fuel into the cylinder. i am getting ready to go on vacation in this thing and need it to be running right. i do not mind spending money to fix it but i want it repaired. last time they told me what it needed it did not fix it (fuel pump)
any input is appreciated.

light should tell you which cylinder is the problem. normally bucking is caused by missfire. that would be coil, sparkplug, fuel injector, fuel pump, fuel pressure regulator in that order... how did they jump to the pump first?? did they measure the pressure? did it leak donw? code should say if #6 cylinder is the problem, then NORMALLY you would start with a new coil.

I would check to see if the imrc linkage rod is still connected. Wanna bet it's a p1518 code??. Any pinging(spark knock) lately?
The rods are held in by little plastic bushings and will throw a code if they break and the rod falls out. If you feel down in back of the engine behind the upper intake manifold, you should be able to feel the linking rod.
Let us know what you find.
Oh...and stay away from the dealerships and you'll save lots....
My local dealership charged my 11.73 each before taxes. Dorman makes the part(can't remember P#) in their "Help" line of repair/replacement parts...should be cheaper than the dealer.

Sorry to hear of the fine competency the dealer has shown.
We need to know the code/s you have set, first.
There may be mutiple issues as well.
Solve for one code at a time to keep confusion to a min.
Good luck.

THE CODES ARE AS FOLLOWS
P1519 -IRCM STUCK CLOSE
P0171 BANK ONE LEAN
P0175 BANK 2 RICH
P0306 CYL 6 MISFIRE
P0316 MISFIRE FIRST 1K
P1519 IRCM STUCK CLOSED
THEN THEY SAID MODE 6 NO MISFIRES
KOER- ALL PASS
THE SAID I NEED THE INTAKE BECAUSE OF SOME SORT OF SCREWS AND THE SERVICE BULLETIN SAYS IT WILL NEED BOTTOM OF INTAKE
THANKS FOR ALL THE INPUT

P1519 appears 2 times so 1 code down already.
Very unusual for one bank to have an "oppisite code" from the other (P0171 & P0175), one lean and one rich.
Both codes likely due to the same fault. Count as 1 fault.
P0316 and P0306 go togather so 1 fault here. 316 is detecting the #6 cylinder fault at cranking time.
You have only 3 area to address.
Fix the cylinder miss first and 316/306 will clear.
The 171/175 codes may be related to the intake/runner/manifold control issue.
A good tech will take these relationships under consideration and solve for interelated fault causes.
I think they are mostly out of your present ability to handle.
Good luck.

It's in the dealerships hands now...Usual song and dance, leaving you with a light wallet when the day's done, but as the OP stated, he doesn't mind spending money to fix the problem.
1065 for the manifold, new intake runners(?), you know they're gonna ding him for a new runner control, yada yada, all the associated parts,throw in labour .....
*#$@#!% dealerships..never been to one that didn't try to rob you blind.
MHUNLEY...Let us know how it turns out.

My 97 F150 was not getting much power at take off. Felt like it was trying to started but needed a walking cane to help it get up. Once it started moving and the rpm got up I could feel the IMRC valves open up. So I unhooked the control modules from the runner and opened the valves and I have power through out the rpm range. There may be something else wrong but it is running good now.

Something you might need to be a where of; the IMRC code won't 'blink' the CEL but an ignition failure can.
That may be the reason the motor is running so poor.
An IMRC fault won't make the motor run rough.
Look for a cylinder misfire code... and..... repair the IMRC hardware.
The IMRC is a rod running through each side of the intake manifold runners.
On the back end of the intake manifold each side is the actuating hardware the code is referring to.
Good luck..
