mad misfiring

[Angus]

did my first spray run of the season tonight at rt66 and broke something...

first gear ran fine, then second wasn't accelerating w/ spray...

It was misfiring pretty badly and so I parked it and pulled out the front bank of plugs and they all looked fine.

rear bank and the first one I pulled was this:
completely took off the metal overhang part and the porcelain is all broke up.

(I know it's a bad pic but eh...)

so I replaced that plug and it was still misfiring but not as badly.
I then got a code reader to tell me there are multiple misfires and misfire in cylinder 5 which is in the rear bank driver side. started to pull that plug in the advance parking lot in batavia, but I got sick of my car and decided to drive it some more misfiring home and just work on it tomorrow...


Anyone know what could have happened to cause this? I've had a nitrous intake backfire and now blown plugs...

and crawlin, saw your companies mustang there runnin. looked good and sounded mean as all get.

in for chipped piston

tho, the gap isnt closed its just gone so maybe you'll get lucky

with nitrious u should of been changing your plugs or at least checking them alot more... lets hope that piece isnt still in your engine...

your engine was running to hot, or the plugs were getting old and weak. and sadly they break apart liek that

and im going to have to agree with mike sadly.... it doesnt look good for your engine

it's gotta be out of there by now since it's been driven 30-40 miles already since it happened...

these plugs were changed back in oct when I blew apart my UIM. They had about 4-6k miles on them and the ones that were good from the front bank looked just fine...

hopefully it's not a chipped piston (or 2...), but if so, piston and ring sets for my motor aren't hard to find and I'll have a new learning experience of pulling apart a motor. I'm pretty pessimistic. haha

lol well good luck... and lets hope

i think you burned up a valve or put a hole in the piston.

If the electrode was in the cylinder you more then likely scored the shit out of the cylinder walls due to not shutting it off and running it for miles.

get a borescope itll tell you lots without taking the head off.

moral of the story...a sebring might not be the best candidate for nitrous. i think the blown up intake and now melted plugs/possible burnt valves makes that pretty clear.

Im going to bet a chipped piston or bent valve like everyone else. You need to pull timing when you spray, and you have no way of monitoring knock or A/F ratio. IMO you were just asking to break shit.

inb4forsalethread, Just kidding, Good luck.

 

[Angus]

you live and you learn.

we'll see what's up today.

 

[Lord Tin Foilhat]

ya goodluck...

engine swap time.

 

[LSx S10]

engine swap time.

time to sell would make more sense. that way he wont have to drive a chrysler anymore.

 

[Bob Kazamakis]

thats what i would do. if its running ok at idle i would drive that shit to carmax and trade it in for a G35. but thats just me...

 

[LSx S10]

this whole time i thought it was a stratus..

 

[Bob Kazamakis]

does it matter?

 

[Angus]

looked in two of the cylinders with a borescope and both were no good.

gotta get it rebuilt or get a new motor.

get a new mill, Im sure itll be cheaper then having a butt ton of machine work done to that block.
