I have a 2002 ford escape i have replaced coils plugs injectors cat and have good compression am getting fire need to know what color the wires are for injector 6 still missfire

The easiest way to test if the wires to #6 are sending the signal to the injector is to get a noid light and plug it into the harness at the injector providing there is room to access the injector from the injector.

Often times, the positive voltage feeds all the injectors, while the PCM applies ground to each individual injector.

You will need to test continuity from the #6 injector to the PCM with an Ohm test providing you have 12 volts at the injector. The ground opens and shuts once with each intake cycle to provide a fuel charge, so it will blink rapidly. That is normal. If the noid light does not come on but you confirmed 12 volts positive, but no ground then you have an open between the injector and the PCM. If the noid light comes on but does not flash or flicker, then there's either a short to ground in the wire from the injector to the PCM, or a faulty driver within the PCM itself causing an internal short.

06 4.7l dakota new plugs,coil pack,switched injectors, compression good no oil in water or water in oil still check engine light ( # 8 misfire) Dodge dealer saying either head or shot engine

You're changing/swapping a lot of parts, but are you getting spark on #8 - at the plug? Is the injector actually getting a firing signal (use a noid light to check)? Can you actually hear the engine missing/skipping, or are you basing this all on the CEL and (presumably) P0308 code?
If the compression is good (as good as the other cylinders), and you are getting spark at the plug, and the injector is getting a good signal, I don't understand the dealer diagnosing a bad head or shot engine. These would indicate a mechanical problem and compression would be the indicator.

Sounds like #2 is still missing. Misfires can be caused by an ignition problem, a fuel problem, or a mechanical problem where there is no compression in the cylinder.
Okay, you have changed the coil. Now try changing spark plugs and the spark plug wire-Swap #2 and #1 spark plugs and the plug wire too, and see if misfire follows now on #1. If it does, bad plug or bad plug wire. Of course you could just drop a new plug into #2 and see what happens. If no change, swap the plug wires and test again. If still misfiring, check the spark at end of plug wire-you need to see a blue snapping spark to know the ignition is working good on that #2.
If you have spark there, need to check if the injector is pulsing and spraying fuel into the cylinder. You might be able to feel the injector pulse if you hold a finger lightly on the injector while engine is running-should be a steady, rather rapid click feel to the injector. If not sure, have the injector circuit checked. You can buy an inexpensive "noid light" at auto parts stores, one that fits your injector circuit, plug it into #2 injector, and crank the car over or run the engine and watch the light-if working, the noid light will be blinking. This verifies the circuit is good. If the spark plug is wet with gas when pulled out, that would verify that injector is spraying fuel into the cylinder.
If still no help, have the compression checked in #2. Low compression from a valve problem or head gasket problem can cause misfires.
Good luck.

I am having a misfire on cylinder 2 but not sure how, I replaced the head, the plug, the wires and the coil pack....what am I missing. No pun intended.

Run tests to see why missing: spark test on no. 2, need a good blue spark to rule out ignition problem. Gas test: make sure injector for #2 is pulsing-is gas getting into the cylinder? Pull the plug after cranking a few seconds and see if wet with gas, or check for a pulsing signal on the injector. A "noid" light can be purchased cheap, it plugs into injector connector and blinks if wiring is working right.
If still no help, you need a compression test to check compression on #2. Low compression may indicate a head gasket failure or valves not sealing properly.

Po 306 engine missfire on no 6

If all you say is correct, then smoke test the intake
& you should have a vacuum leak next to #6

Next do a cylinder leak down, verse a compression test

Always do leak down,don't care about compression until
you fail the leak down

What could I do to stop my lt1 from missfiring

Lets see coil pack, spark plug wire, spark plug, and if it is MFI maybe injector, or check injector pulse. If all those are ok, then check the compression in that cylinder, if it is low it will not fire right. Go through normal check out procedures to check each of these pull out the spark plugs, put them back on the end of the wire and check for spark. If these are ok the go on go the injector. If they are not try temporarly swapping spark plug wires with a different coil pack, if the problem follows the wire, then put on new wires. If it does not follow the wire, then the coil pack could be bad, or the signal going to it. If the spark is ok check to see if you have injector pulse signal going to injector. If it is ok replace injector. Hope this helps you.

1999 saturn SL2 - #2 cyl missfires - coil,wires,plug are good- bad injector?

could be, but...
make sure you have good spark, compare with another cylinder.
You can use a noid light to see if the injector(s) are getting the electrical signal to "fire" fuel.
You can run a compression test on all cylinders to see if mechanically they are all sound.
What I do, is swap injector #2 to another cylinder and see if the condition follows.

My check engine light came on. It says that cylinder 2 missfire

Sounds like you due for new spark plugs and plug wires(If applicable). Also possible causes are cyl 2 coil pack, injector, and/or compression but not likely. Check plugs and wires first.
