Default Fuel injector replacement tips?

Ok, i think i finally narrowed down my rough idle issue to a poor fuel injector. I tested each injector and they all read 11 ohms but came under at 10 ohms. I know i should replace all 4 but i don't have that cash now. Any tips on any special tools for replacing this injector? Looks like the upper radiator hose has to be disconnected though.

bring a multimeter to the boneyard and find a pretty one that tests OK?

Just about to do this to mine as well ('09 TE). Like the junkyard idea instead of four injectors.

Be sure you relieve the fuel pressure BEFORE you start.

I used a hand pump to remove some/enough coolant, cut the stock spring clips (carefully so as not to damage the hose) with my muffler cutter. I could then unhook the thermostat end and rotate the hose up and out of the way. Not a huge deal, but saves draining from below. You'll need two new hose clamps, and it will be easier next time.

Also, you might want to use come compressed air to blow all the junk away from the injector ports before removing them. This helps keep anything from getting into the manifold. A shop vac might work if you don't have a compressor.

The injector gaskets/o-rings are inexpensive. If you're going this far, I recommend replacing all of them.

There's also a number of videos on YouTube for cleaning injectors that might help. Won't fix the resistance problem, but I'm told that cleaning every 30K is recommended.

Good luck!
