one more question, if there was a piece of porcelin that got into the cylinder, what kind of damage can that cause. i checked compression after the whole ordeal, and it resulted in 140,140,145,146 with the car not fully warmed up?

 

no it will not reset your dynoflash, and yes if a piece of porcilne fell into your cylinder it could do some damage(scratch walls, nick a piston) but the easiest way to check that is get your compression gauge back out and see if the cylinders are to spec if they are i wouldnt worry about it. also like some one else said do not over torque your plugs

 

i did the compression test after i suspected the porcelin piece...the guy at the shop put the plugs in and he put them on about as tight as physically possible..i guess this could be the problem

 

this is a problem use the spec torque.

 

also you ALWAYS want to check the gap on your plugs before you install them, you dont know if the gap is correct so take the exta 10 sec to see if they are all within spec

 

i would never let that guy EVER pick up a wrench around my car again the first thing you learn when putting in a spark plug is to not tighten it too much but just enough

 

the porceilan could have scarred the cylinder wall, got smashed into a valve or valve seat, or just got stuck in the head or piston.

question:

what inclined you to do a compression test anyway?? was there something else going wrong?? did you have problems before??

my suggestion would be to check the spark plug socket to make SURE that the extension does not touch the top of the spark plug when you put them back in. sometimes the extension will potrude into the socket and be hitting on the top of the plug. it is really easy-as you have found-to break a spark plug if you are not careful. just take a plug and put it into your socket to see if it sticks up into the area where the extension goes. if that is the case, change sockets or get the 6" spark plug socket.

take it to the dealer. since you broke the porcilin on the spark plug and let it rattle around a bit, just think what it would do to your turbo spinning at a couple 10000 rpm....



you should quit while your ahead.

 

Damn diiirk sucks to hear that about your car. Hope you get everything worked out. What shop did the work to your car?

 

it was crd...im not holding anybody responsible as we dont really kno wats wrong..but i can say that the plugs were tightend pretty damn tight, also im not even certain that the piece even made it into the cylinder, the whole plug is covered by the socket when u take it out, and i found a big piece of it on the floor near my car, and theres was only a tiny piece missing

 

Damn I was hoping you was'nt gonna say them. You should just do what these people are saying, and put it back to stock and have Mitsu take a look at it.

 

The compression seems fine. Usually it would be bad if there is a higher percentage difference between each cylinder. To raise the 2 cylinders with 140psi, you could put a capful of oil in the combustion chamber.

As for the porcellain, a piece could have fallen in there if you are missing any near the electrode. But, if you are, I would just take it to the dealer. That piece will eventually work it's way to a spooled turbo spinning at 100K RPM...yes...100,000 RPM!!! And even a tiny piece of anything can wreak havoc on your snail.

For the gap...You "shouldn't" have to gap the iridium plugs. In fact, gapping them may cause more problems as you could damage the electrode. Checking tolerances is fine...But no gapping. For the guy who tightened the plugs so tight...At least the plugs are the stock part number because if they were longer, the piston could slap the plug tip.

Sucks with the issues. I would reset the ECU for 15 mins and see what happens. Just tried to give you some good advice.

Not to be a jackass but if you are having this much trouble with installing spark plugs, I think you should probably quit while you are ahead and just have the car towed to the dealer and let them fix it at this point.

 

well we will see tomorow...if things dont work out tomorow then il be taking it to the dealer...gotta put a few things back to stock and il drop it off..like i said, i highly doubt anything got into the cylinder, i just dont really understnad how brand new plugs can misfire like that

 

yodobashi, thanks for your reply, it really helps the situation
