pulling coil connecters

[demonZ73]

ok so i pulled coil connecter on cylinder one while running and sure enough idle dropped and then i did 2 3 and 4 but the idle did not drop indicating probly bad coils in cylinder 2 3 and 4.............however i ended up pulling all coil packs (and attaching a spark plug and grounding it) 1 2 3 and 4 and they all got spark, and even switched coil packs around to make sure it wasant the connecter or wireing ............can anyone maybe help....thank you

Test your injectors, they are known to go bad. They need to ohm out at 10-14 ohms.

i jut replaced them freak and ohmed them and applied voltage to them and heard them click i think i need a MAF and thats just messing things up so bad

I know the MAF can cause a ton of issues, but it will not make your cylinder not fire. With all these problems, maybe you should get your ecu checked. That could be all your issues. Unless someone has hacked your wiring harness up before you owned the car.

You should definitely replace the MAF, but like nissanfreak said that wouldn't cause cylinder misfiring. When you put the new injectors in did you make sure you didn't pinch any of the O-rings?

i was carefull putting new injectors in and was most sure i did not pinch an o-ring however it was my first time doing it........im going to get the MAF and give that a try before i ask anymore damn questions on here lol.......and from what i hear a bad ecu wont thro codes but mine has so it should be goos right.....thanks
