I just put a bottle of Techron Fuel Injector cleaner in mine. Have to give it some time to work thru. 

I have run the NOS Octane booster on long trips and it does seem to help get a few more MPG. 

I Have a long trip end of the month coming up, so getting it ready for it.

I've been trying out the Lucas cleaner. I think it has done some good but much of it may be that the temperatures have been lower the last couple of weeks, so we'll see how it does longer term.

I have also started using the Lucas Upper Cylinder Lubrication & Injector Cleaner for the past 2 tanks. Have noticed ICE is quieter and appears to runs smoother (less vibration). Weather has been betting colder, so unable to easily determine if fuel economy has improved.

Problem fixed.   
 

The vibration seemed to get better for awhile, so we didn't bother with the injector cleaner.  Then a few weeks ago, after a 30 minute drive on the highway the engine light started flashing and I experienced a rumble from under the front wheels.   Fortunately it was only 5 minutes to home.

 

OBDII indicated #3 cylinder misfiring and injector open.   I decided to replace all four injectors as they're only $40 each (Motorcraft CM-5148)   Fairly straightforward but I recommend you buy the special tool to disconnect the fuel line from the fuel rail.  They're about $5-10.

 

Car is running like new now.  Smooth as silk.

It would have been interesting if you have tried using the injector cleaner before replacing the injectors. :headscratch:  Maybe someone else will try it when they have problems to see if it makes a difference.

Using the injector cleaner after the engine light started flashing and all those error codes came up?   No way.....#3 injector was done.  I suspect the earlier engine shuddering was caused by the injector being on it's last legs.   Maybe #1 too.   In any case it made sense to replace all four as it only cost $160 in parts and the car is almost at 60K miles.

Just makes me wonder with 215k miles, probably 105k ICE miles my injectors are still running fine with injector cleaner every 20k miles.

For future reference (unneeded, I hope!):

 

What is the tool?   A flare nut wrench?

 

Can obdII distinguish a stuck or dirty injector from an open injector?

 

Did you check with a meter to confirm the injector was open circuit?

 

If the injector showed up in OBDII with a code for "open", I assume it means the coil is burnt out or there is a connector problem.  I myself would check the injector with a meter for continuity before pulling it.  If the injector coil was indeed open circuit, then injector cleaner is not going to help.

This is a Canadian site, but they call it a fuel line disconnect tool:

To be honest, I didn't have time to confirm the injector was dirty, stuck or simply bad.  But it would make sense to check it out.
