As I was going home from work, I noticed I was pulling 8-10 lbs boost going up light grade hills. I thought something isn't right as I would normally have negative boost. About 5 minutes later I got a cel and car was misfiring and died. Pulled onthe side of the highway and got it started barely. She went into restricted power mode just enough to get me to an exit. I ran the codes and they all said maf and misfiring. So I replaced the maf to no extent. Had to tow it the rest of the way home. I can't remember the exact codes off my head, but anyone have any ideas? I'm at a loss here. Possible cat clogged?

 

your cat is melted. exactly what happened to mine except it didnt happen in a day. more like 1-2 months of abuse from n2mb NLS.

 

Wonder how that happened? I had cruise control on 75 for at least 20 minutes going down the highway. Should I pull off the exaust pipe before the cat and see if she runs?

 

And thank you for your response

 

Update: it was the cat. Had to loosen the bolts on the downpipe to get enough flow to start the thing and she fired right up. Apperently there is a 10 year 120,000 mile warrenty on are cats. So even though I have 103,000 on my car, it's still covered.

 

lol exactly what i did. brought it in, they put a new one on. i took it off same day, flipped it for 180 bucks and installed my catless haha. win!
glad it worked out good
