missing on # 2 and 6 getting blue fire just did a good tune up platnum plugs n all new cap and rotor kit n wires now its missing on 2 and 6 cleaned the injector conectors but it was no help plz some help me

Check or replace the spark plug wires first. This is a quick and cheaper fix. If that did not work, then perform a compression test on the cylinders. They should be about 125 -150 psi. If they are ok, then the injectors are bad and need to be replaced.

thx i have done a full tuneup on it it gets fire blue fire but still misses n i love my car plz help

[coolhand]

Did you perform a compression test on the bad cylinders yet? That will guarantee the cylinders are ok. Nissans are notorious for bad injectors.

umm i have not done a compression test i no its gunna sound dumb but i dont know how to do it cheap or really at all exept send it to a shop and i dont wanna do that i cant afford it + i like doin the work myself so i learn but how can i check the inj? thx 4 the help

ok i did the ohm test it was inconclusive so i changed the coroded pigtail

If you have spark to both cylinders it almost has to be the injectors. Quick test would be to put a screw driver on the injector and listen for the clicks. You can also check the resistance of the injectors with a multimeter. Look for between 12 and 14 ohms.

Edit: if there's any corrosion be sure to clean it off as best you can, that will definitely cause some issues. The front injector harness also has a separate plug that connects it to the main harness. Follow the wires from the front injectors and you'll find the plug, make sure that plug is clean of corrosion as well.

Good you got it running

Hey just so you know. This is what I have been told.

Once Plats or Iridium plugs foul, they are no good. Sooooo might want to 2 new plugs. They will run fine I guess, since thats what I was doing... But they are not as good as the other 4 now. Its what I was told.

Once they foul they are fouled... and you DO NOT gap them. Leave them how they are

just my $.02 on the plats and iridiums
