Why don't posters tell what year and engine they have in the title of their post? At least this guy did have it in his profile, but more people would answer questions if they knew what engine the question was for.

Uhh...us WJ guys are superiour to all you other 4.0 n00blings.

We have TWO manifolds that are separate to reduce cracking.

Carry on with your n00bliness, n00blings.

I got a wj 2000 4.7 and just noticed i have a exhaust leak. now that im investigating more I see a bolt is broken. Damn. And its about 100 degress out. WHew!! My question is would the leak cause the jeep to run iratic and shut down?. Or would that be my ecu getting stupid also at the same time. Some one told me the jeep may not be getting a good o2 reading since the exhuast leak is leaking. and would cause the truck to surge like its doing at times. Im going to fix the leak right now. I just hope this takes care of some of the problems. Whos had a jeep with a fried ecu? a 4.7 that is. My lights would flash somtimes at night for no reason? Anyone seen this also.
