What's your diagnosis?
 
I was driving on the HWY and I was doing about 55 and I dropped it into 3rd gear to pass when I seen the engine check light flashing. I immediately let off the throttle and put it back into auto. The jeep drives like normal now just the exhaust is a little loud like something funky is going on with the exhaust. My friend had a cat go bad on his Frontier and is sounds similar to that just not as loud. at idle it sounds fine just when I go to take off it sounds like a crappy exhaust system. I checked to see if there were any codes stored and none came up. .

1. What to you think it is?

2. And if it's the exhaust is that covered under the "Bumper to Bumper' warranty?

I guess you couldve blew the cat and blew the honeycomb(whatver its called) out of it. That would be coverd unless there is any visual damaage to it.

The flashing check engine light under load sounds like a misfire condition, but the other have sounds like a partially blown out cat. The cat is covered under warranty, I think its longer than the normal 3/36 by federal law.

Generally, if it is a cracked component of the exhaust system (exhaust manifold, lose doughnut connector, CAT etc) the problem should be louder and more pronounced while the engine is cold and be less noticeable while it heats up and the metal expands. Just a thought.

I noticed it when the engine was cold and when it was running. Well it's like 90 degrees here today too. LOL I'll take a look at the exhaust later. There's def something funky going on in the exhaust. But I don't know why a light hasn't gone on yet?

yeah IDK whats going on nate...I had a header-leak on my old dodge and it threw a cel, then would go away, then come back...can you hear anything different at idle? or is it only when driving/shifting? any notice is power loss/responsiveness?
