My understanding is that Jeep engineered the 4.0 to run slightly lean to help with NOx emissions, fuel efficiency, and “engine heating”. My guess is that running slightly rich actually increases the fuel air mixture on the jeep to stoic which increases heat output. It may be that the leak can...

I think the collector is the place to watch. Leaks in header probably just push exhaust gas out of the system. At the collector you can get a Bernoulli effect and draw air into the exhaust with the right sized leak.

I meant ECU...

Here is another unusual suggestion. Check the exhaust to header connector and make sure that is tight and sealed. Your O2 sensor is down stream of that joint and if it is leaking the Jeep TCU may think the fuel mixture is off. I installed a RussP new stroker last summer, and it nearly killed...

This a classic roast of the GM and Ford Execs today for flying on private jets to ask for financial help from the government. I bet they stayed and played a few rounds of golf after the hearing. Abysmal quality and ethically challenged executives do not engender much public sympathy...

Most Transmission corridors are easements across private lands. The easement language is specific to the electric utility use. Neither the owner of the land or the easement normally grants permission for any other use. Same principals apply to Transmission corridors on public lands as well...

" GM has closed the quality gap with the imports, and today we are putting our best quality vehicles on the road." Compared to older GM vehicles? I have been burned by some of GM's 3 year or 36K mile engineering enough to see the irony in this statement. Design things to be light, or strong...

My 98 has no body panel rust. The only salt that our roads in Phoenix get is from sweat..

Are they off a classic or limited?

The most ironic part is the thought that either party cares to do the right thing for the country and do not operate to the exclusive benefit of special interest groups. Further, the laws quoted as being waived are paradoxical all used freely to impact the property rights that are later...

I am interested if it fits my 98. I bought a newer style intake that is sitting in my garage and I have been waiting to get a header to replace my cracked cast one before replacing them. Where would you get the down pipe?

is the front axle an HP dana 44?

Kudos to for the strut holder. That is pretty neat stuff. Anyone that has hit their head on the hatch realized what a good idea this is.

How much for the Front Skid?

No just the TNT stiffeners. It has been on my list.
