HI GUYS MY NAMES SAMANTHA AND I LOVE MY 1990 RX-7 NONTURBO

HELP! I NEED TO PERUSE THE CEREBRAL DATA BANKS OF SOME OF YOU RX-7
TUNNING GURU'S. I HAVE THREE PLUGS SHOWING RELATIVELY EVEN BURN.
BUT THE (I DON'T KNOW WHICH NUMBER PLUG) THE ONE CLOSEST TO THE GROUND, THAT IS ALSO CLOSEST TO THE RADIATOR. THIS PLUG IS SHOWING
A THICK DRY BROWN-ALMOST RUST COLORED DEPOSIT. AND THERE IS A SLIGHT BUT NOTICEABLE MISS OVER A BROAD RPM RANGE.

QUESTION: IS THERE A WAY FOR WATER TO SEEP INTO THIS CHAMBER AND THE MOTOR STILL RUN?

IF THE COIL OR IGNITION SIGNAL WAS WEAK TO THIS PLUG, WOULD THE DEPOSIT
BE DRY BROWNISH-ORANGE?

WHAT TEST WOULD YIELD THE BEST INFORMATION COMPRESSION? COMPUTER DIAGNOSTIC?

AND YES I HAVE REPLACED MY TPS SENSORS AND I HAVE OBSERVED WITH A
MULTI-METER THAT THEY ARE WITHIN THE .1 TO .5 CONTINUITY RANGE.

 

wtf ur user name is mitch ur profile says male and yet u say ur name is samantha?? i r confused and als turn off CAPS lock caust if looks like ur yelling

 

did you try just replacing the plug? if it went bad or fouled and doesnt fire/barely fires, the front rotor could be running on mostly the #1 trailing plug (top closest to radiator) which could explain the 'miss' and build up of crap on the plug you're talking about, the #1 leading plug (bottom closest to radiator). if its engine/compression related i would expect both plugs on that rotor would be affected.

 

sounds like a fouled plug, replace them and see if that takes care of your miss

 

and when you replace them, go with NGK's. Champion and bosch make shitty plugs for our cars.

 

check the spark on the plug and see if it is firing. could be the spark plug, bad plug wire...

 

There are two rotors, and each has two plugs. A total of four. Traling=Top & Leading=Bottom.
Rotor 1 is the front one and Rotor 2 is the rear one. Always use anti-seize, and take care installing the plugs. your Rotor housings are aluminum, and can have the threads damaged easily.

 

a girl with brown-rust colored wet deposits, i just couldn't read anymore. kill the CAPS btw..

 

hahaha

 

All of the symptoms are perfectly normal.
Now go research to find out where the reference is for that answer.

haha i only checked the thread seeing how awkwardly funny the topic title was

 

interesting thread....wet deposits...brown in color....

sounds like **** seepage to me....

 

I believe this would require the expertise of a gynecologist.

 

I'll give u a wet deposit alright...

 

Well this thread is super productive.

 

if you want help around here:

1) quit using ******* caps, it annoys the hell out of people
2) i like girls... alot! but trying to get help just because you are a girl around here will probably just turn a thread into crap right off to bat.

 

no wonder why there are not many girls on here..who cares if she uses caps..anyway.."trying to get help just cause yu are a girl"..what does that having thing to do with a plug problem.

 

caps are annoying as all hell, i won't bother reading them because they hurt my eyes trying to decipher, yes it does make a difference to me but not to everyone obviously. the only reason the girl issue was brought up was because of the 'teheehee' factor.

i don't give favoritism to girls over guys here because everyone deserves the same respect, what i do dislike is people trying to get favoritism just because of that difference.

you have to admit the title made and still makes me wonder if this isn't just a joke/flame thread that someone started out of boredom.

 

see first reply to the thread and the user name raises the question I have to say flamer

 

Plus the fact that they never even replied on the thread.

 

Only one or two decent replies to this thread.

Replace the plugs and wires. Plug part #'s IIRC are: NGK BUR7EQ7 x 2, and BUR7EQ9 x2.

And your thread title sucks.

 

IBTL!
