Okay first of all if your #2 plug is covered in "black shiz" that means it's fouled and needs to be replaced. That's what is causing the misfire.

To figure out what caused the plug to foul you need to look at what exactly the "black shiz" is. Is it oil or carbon? Carbon will be a sort of flat black powdery looking coating; oil will be a shiny, slick looking coating.

 

Its Carbon for sure. Seems my plugs keep going bad. Cant figure it out. Oh well, I'll just take it in to see what the dealership has to say.

 

Did you not replace it again?

 

Its 1055pm here, nope I didnt yet. Will tomorrow. I spoke with another whom seems to think I have the wrong heat range plug. Ive purchased plugs from a mod shop for couple years now with over two integras. None of the time did i get bunk plugs. Im sure my wires are fine, the plugs are fouled but very clean looking. Core is super white new. Ring is black, tip is greyish with no crusties.

Now that I think about it, my engine has been hotter since I got new wires, cap/rotor. However, Ive went though 2 sets of plugs, ngk and bosh in two months. Why are both fouling on number 2?

It cant be hot plugs, but whom am I to argue.

How car runs:
idle at 800
revs to 8200k no problem (dont do it though...to much that is)
car kinda shaks at idle, seem like someone is pushing it side/side gently or wind, no a ramble shake.
air out ehaust isnt constant
CEL light upon startup even when reseted.


Now when my vavles neede turning, the light would only come on so often when comming to stop it seemed. I could reset for days and it would come back usually when comming to stop or acceling.

Now it just comes on upon start. it also came on once when I just got it back from vavle adjustment. But I didnt change plugs so mechanic said it might till I do. changed and its back?

 

Hello all,

I have a 2k GSR. Ive got 68k on it. In Dec ,03 I installed new plugs, wires, cap and rotor. Did so, beauce my milliage was horriable. Then in late december, I got hit with a check engine light. Took the car to dealership, they said you need valve adjustment.

They did it with my engine warm/cold, who knows (I had no time at the momen (dec24th) in 2 hours. Mechanic said he didnt like my wires or my NGKs thats were one month old fouled plugs! Hum, he wanted me to buy new wires and plugs. Plugs being 20ea and the stock wires were like 65. I passed on both and said I'll get new plugs tomorrow on my own. These wires would be returned before I purchased stock 7.5mm cheapys.. Three weeks later I changed the plugs to bosh platiums. I did it because I noticed ONE check engine light which DIDNT stay long.

So, its been like 2 1/2 months. I got hit with another CEL light. Checked it out on my own (CEL CHECK CODE TWEAK) and I have a misfire problem Code 72! Thats number 2 plug. Its noticiable too. my idle is ok... but the air flow out myexhaust is sputtery. So I checked my wires, pulled my plugs. Only number 2 looked fouled, switched my two middle plugs to see if it would generate new code on the other plug number and it didnt.

So, Ive got bad plug again, Im still not getting good gas milliage (I use good gas too), my wires are 3 months old and even though there APC there nice. Ceramic base for plug attachment, tight wrapping, so no water it getting it, they seem good quality but who knows, they are APC brand... I wanted ACCEL, but no stock at the time.

What could cause this? Did the valve adjustment with a warm/hot engine do nothing? Should I make them redo it? OR is it my wires? And if wires, why is my two plug so dirty/fouled? Could it be fuel injectors need cleaning? WHY AM I GETING FOULED! WHY AM I MISFIRING? WHY WHY WHY!...Lol Help me out peeps! PLEASE!

 

Hey man, I just got done changing my plugs lol .

I don't know what else to tell you, replace the plug, see if you can have someone check the injector. I'm not to familiar with injectors. Make sure that it is gapped to 1.2-1.3mm (.054in) and torque it to 13 lb-ft.

Let me know what happens after you replace the plug. I run NGK's at all times .

 

Well, checked all the plugs and only one is somewhat fouled. Number 2 that is. I put #2 in other spot, last night. Went turned it on, and still had the check light. Started it this morning, and its off now? Its got to be the plugs. But WHY are the going bad or causing me issues? there only 1k old? The ngks were like 3k old? Seems that my car is eating my plugs. BUT the worse one, #2 was greyish prong, black carbon like ring around the base, and the core was as white as it was when I put them in. The only dirty carbon area was the base ring. And my engine seems to be hotter than normal. My vavle cover is much higher in temp than it ever was. Someone suggested my plugs might be to hot for my car. Then again, there the same plugs I usually buy over my ngk's. I took it in this morning for a free once over from the dealership. I know I have a code 72, so Im eager to hear what they say. Last time I took it in for a vavle they said code 72. Seems that vavles werent the issues the first time? Who knows. im giving up.

 

Went to Dealership.

They continue to say its my wires causing the misfires. They still havent answered my fouled plug issue. They continue to say, lets narrow it down. Well, I have the stock wires and there asking me to put them on, try it out and see what happens. If I get another CEL then they'll check the valves again. Seems to me that there ignoring the issue. FOULED plug!!! To my knowledge, wires cant foul a plug? Seems to me that the BOSCH platiums I am using (which ive used before) are running real hot. my engine seem hotter since I put them in. Another dealership i called said BOSCH were the worse ever! So, Im going home, changing my plugs, putting the old wires on to see what I get next.

They said my APC 155282b wires were HIGH RESISTANCE. Well I dont beleive that. Ive used them before and havent had any problems. The mechanic swears its my wires but he looks cluless when I ask, how can my plugs foul? He didnt say anything about BOSH being bad?

I dont know. Seems simple to fix, but yet all Im hearing is wires. I'll change my wires to stock. Going to get some NGK platiums, and see what I find. Im wondering if the vavles are to tight? Engine seem much hotter than usual? And the head is were the heat seems to be comming from? Perhaps my bosh plugs and the cheap non platium NGKs I was using cant hang?

Do you guys my plugs are a issue?

I went from stock to NGK non platium 2.50ea
I then went to Bosch platiums 1 week after vavle adjustment
I still see a hot 2 plug on both...

 

i have the same problem with my 2000 gsr , and i keep having the check engine light go, they said it was a m isfire, after i brought it to dealership several times, it keeps coming on after a week or so, and finally doesnt come on no more

 

interesting....
