"A car drove by"

Sorry, I'm not going to be of much help, but Holy Crap.....that is a ton of smoke and thumping!


This is gonna sound stupid and I'm sure it is.................but have you checked your oil level? Did someone overfill it?


I think the tribe in the other county is preparing for war after those smoke signals you just put out!

 

haha, those are steam not smoke
and no I didnt overfill the engine

 

How do know the cat is bad?

Sounds like fouling to me.

 

dealer is replacing the cat for me. got P0420

 

Phew...................was gonna ask how cold it was when you did this!

 

thats very simmilar to what my idle whould sound like when my plugs were all fouled up. I was thinking that maybe since you have the 3rd oil injector that you need to run it up to redline more than us with two cuz the oil is whats fouling it?

 

just because of the way the smoke puffs out here and there, and isnt constant as it should be, i'm willing to bet this will go away once your cat is replaced.

 

lets say its been below 30 a while.

 

yea. lets see how it goes.

 

it only happends when warming up, when it drops below 1500rpm everything is fine again.

 

ok it appears to be only after when air pump turns off and before it drops below 1500rpm, so I think it might be the cat not doing the job.
