Exhaust Problem

[BENC911]

Well so i just noticed something weird. I parked the car after driving it for 15 to 20 mins and left it running while i went to get the mail, and when i come back I noticed that 3 out of the 4 pipes where smoking nicely but one was not quite as strong. I put my hand on the one that was not as strong as the others to make sure smoke was coming out, and notice the small amount of smoke coming out was cool! I then place my hand near the others and the smoke was hot as hell! What should I do, I am sure that is not normal! The car drives awesome, very strong, but i am sure that is not a good sign. The one all the way to the right is the problematic one.

 

i bought a durametric and i will run it and show the results here, but any idea will be appreciated.

Always best to start with the year and model, plus any modifications, especially in your case, to the exhaust system.

OK, you car should have dual pipes coming out of each side mufflers, which could indicate a blocked passage in the muffler, or possibly a partially hung open by pass port:

You mentioned that you had codes for misfires in another post. I would start there. Recheck with your brand new Durametric and then start with the cylinders that are miss firing. Check coilpacks and spark plugs and wiring for corrosion and freying of wires.

 

Bypass above is also a great suggestion to check and make sure is fully actuating.

If he has an obstructed exhaust, I would not be surprised he has misfires........

this is way over my head, i noticed that in the durametric there is no misfires but it could be because i clear all alerts first. i am going to take it for a spin and redo the durametric i am sure the misfires will come back. 

 

i will then have to take it to a mechanic, but i am not sure i want to take it to a dealer. from you guys dealings here, any good mechanic in NY area? i am close to yonkers.

 

i will repost the durametric after the spin.

well very interesting, now i do NOT have the check engine light on and the misfires are gone!

 

I have no clue! Should I worry about that exhaust stuff?

well it came back, check engine light, and the System is too Lean! what ever that means.

I re-ran the durametric and also recorded the pipes very close, they appear to have water! Could that be? Again the car was in a flood but i am so confused. Is water like that out of the pipes common?

When car's start from cold, it is not unusual for them to drip some water from the tail pipes.  However, if there is an unusually large amount of water coming out, or it continues when the engine is warm, something is wrong.

Great thanks it is only when is cold, thanks for the clarification. After driving it for a while it doesn't do it.
