I don't understand if the spark plugs have something to do with your other problems.
I believe Normal Leading NGK Spark Plugs are BUR7EQ which is hotter than BUR9EQ which is for Trailing.
What does this have to do with your problems? Can someone clarify this 'coz I don't know what's up here as well.

 

ok...the spark plugs are marked with a L or a T. t=trailing l=leading. 2 trailing plugs go into the upper holes, 2 leading plugs go into the lower holes. Also make sure you connected your spark plug wires correctly. The first coil closest to the front bemper is the leading, the one in the back is trailing. The difference between the trailing and leading plugs are the spark temperature. Make sure you have the right plugs.

 

well look the spark plugs i took out were all having a little L soo i bought 2 T's and 2L's put em on rigth and it was making a noise like hitting something .... do you really have to tourqe the plugs down cuz i got em tight in there .. soo maybe there in too much or too tight .... im stilll confused

 

also when i rev the motor it made a noise i never heard before

 

hmm... no it isnt necessary to torque them in, but you dont want to make them to tight. Make sure you got the right spark plugs. Usually people mess up on that. Did you double check that they are installed properly and the wires are correctly wired?

 

YeeAh`` I think most people here know that..

 

ok check this out im lookin at the spark plugs that it had before and there all the same number (BUR7EQ) for the new ones i bought trailing (BUR9EQ) and leading (BUR7EQ) those aer the ones ..... but yea do i hand tighten the plug and one turn with the rachet ?

 

hey tho what i dont understand when i got the car why the was the car kool with the all 4 leading spark plugs >>> not even one trailing ... im gonna take out the plugs tmrow morning ...

 

some people mess it up man. you will be surprised what some people do. Just make sure the spark plug is nice and snug, no need to over tighten. You may have touched your spark plug wires to a ground. This will mess up your igniter/coil. Doesnt happen often but could. If your still confused check the tolerances of your coils. You may have disconnect something when changing your sparkplugs. I kno the oil sensor plug is just a small clip on that you might have knocked off.

 

Iiiiii donnn't know how much turns, maybe you got a broken ratchet and end up who knows how many turns...

I just keep mine nicely snug. I oil the thread and hand tighten them first, just like any other nut and bolt...
I believe 2mm Gap on those Spark Plugs..

 

there might be an issue with your car. i believe leading plugs dont fowl up as easily as trailing (on a lightly modded or stock motor). So they might have put some more oil in the motor for compression reasons and put the leading plugs in so they wouldnt fowl up just so it would run decent.

 

but dude i have the NGK plugs do i really have to gap em ???

 

soounds like you mixed the wires up ..It happens ..I gave you a quick Pm NUKEALL..and the TACH..it runs off of the Trailing (reads spark) so,there ya go..It could have been done..hope the PM clears things up for ya..

 

man dude thanxs my friend on the forums ACidangel i think thats his name on here but yea hes gonna come down to help me out but yea thanxs man .... but dude it made a sick whining noise when i rev the motor ..... you think it be misfiring ? cuz the wires are inthe wrong order .....?? and my rpm gauge and oil pressure not working ?

 

miatersty its not that my NGK's are the RE ... from japan dude ... i it makes that clankin noise when i rev my motor ...... and my oil presure and tach dont work..... soo im confues but yae thanxs
