ok so if u dont remember about 2 weeks ago i posted that i found out why my car wudnt start. would crank but no fire. it was the plugs, replaced them ran fine then the ignitor went out, replaced that ran fine, now its back to doing the same thing as b4 with the plugs. pulled one same thing as last time. fouled a 2nd set in a week.....bought another set of plugs gunna replace after work, but does any one know why im eating plugs by the week?

Called the ngk rep told me to gap the plugs to .040 and try that, also was told this is signs of the egr system the ports on the intake? possibly i got a bad o2 sensor? all are some my ideas. any input will greatly be appreciated.

 

i couldnt see it bein ur o2 bc i drove around over a year with my o2 not plugged in/broken and my plugs never fouled

 

what do they look like when they r fouled. maybe they r oil fouled or something.

thats a pic of the best looking one. the others are lil blacker.

 

well from what i can see they dont look 2 bad. maybe your ignition coil is taking a dump..

 

timing all right?

 

Is there a CEL?? any mods prior to this problem?

 

coil i tested its good, im gunna re time the car, and no cel's

 

That one doesn't look that bad to me. Show another one.

 

trust me there are bad. that pic i showed u was the best one. the others are solid black and 2 had fuel i believe. ima change my plugs 2 morrow and ill show ya some more pics

 

replaced plugs fired right up. ne other ideas?

these are 1 week old

 

looks like a lot of carbon buildup to me. check your fuel lines, filter, rail, and injectors. maybe you could try to add fuel cleaner additive to your fuel tank.

 

hrm ive got a new filter, oive used additive but ill do again. ima re time it Thursday with a snap on timing light. i hope that will fix it. i aint going through a set of plugs every week eff tha

 

good luck chris.

 

How old is your current O2 sensor? Wouldn't hurt to take a look at it...

Also how old is the cat? No CELs?

 

o2 is like maybe 2 months. cat same. and no cel's

Hmmm...cam and ignition timing is good? Wouldn't hurt to get an AF gauge...

 

cam is good im retiming 2morrow with a snap on timing light. if it stills bad ima get a gauge.

 

Seems silly, but is your air filter clean. I haven't really heard of a problem like this so I'm sorta just throwing things out.

Here is a site on reading plugs:

I'm guessing you have already looked at something like that.

When reading two-stoke plugs(the only experience I have) you will replace the plug, and then drive in the range in question(1/4 throttle, or 1/2 ect) for a few miles, then kill the engine and coast to a stop. Pull the plug and look at it. That seems alittle extreme in your case as there shouldn't be a problem with the mixture. It almost has to be something(sensor) that controls the mixture. I don't really know enough about these cars, but I'm interested to find out what's up.
Good luck.

 

If your O2 checked out good, check for vacuum leak that could cause the ecm commanding a rich condition. Or there could be other possibilities

 

After actually looking at the link I posted it really could be oil.

Do a plug chop before they actually stop firing so you know if they are wet then its oil, and not fuel.

 

iv driven on the new plugs for a day now. no vtec yet. ima time it in a few hrs. then ima give it some hell and see what it does. try and foul em with alot of hi rev thats usually when id start noticing them sarting to act up. so well c. thanks for yalls input ill let ya know what i find out.

 

they look oil fouled..

 

It could be a pinched return fuel line or a bad FPR check your fuel pressure

 

Also if there is a leak in the exhaust manifold before the o2 sensor that could also cause the ecu to run a rich mixture.
