ricchief556,
yeah, it helped with not hitting the brake pedal. i was driving all through it that friday night when the blizzard hit. my ses light hasn't come back on, so i'm pretending that it magically fixed itself. on the other hand, i get the three amigos every time i hit the brake pedal.

 

the code is mostly from an air leak between the intake and the exhaust. A smoke test might reveal the answer but if no visible leaks seen then perhaps the intake is warped and sucking oil up as well. Time for an intake or headgasket job if its leaking coolant. Recommend a new pcv separator as well.

 

ok, been driving the truck hard and she finally spit out 2 more codes. So total I'm getting P0174, P0150, and P1174. Any clue as to what this could be? Thx for any help.

 

They are all O2 sensor codes, Too Lean Fault Bank B, Cycle Fault *Codes* B U, and the p1174 is another O2 code that the engine cant compensate for the lean running on bank B. It sounds like your exhaust leak is so bad that the 02 sensors on the passengar side think the engine is running lean (when its not). SO lean that the engine can't compensate but is trying and that is why your MPG sucks.

 

hey, thx alot hilltop...i guess i'm going to have to replace that gasket after all....i'll see if that fixes the problem.

 

FYI - i just noticed a 'drip'....looks like coolant. please don't tell me head gasket.

 

you need to find where the leak is, clean everything up and add some dye to the coolant so you can see if it is the valley pan gasket or something else.

 

So I dropped the truck off at my mechanic to do a pressure test on the coolant leak...test came out negative, ran her for an hour and a half and still nothing. He said they found no leak. He told me that it was most likely my o2 sensors. Bought all four from ABritish. Any tips for installation? Where are they located? Thx.

 

you need to download the RAVE manual. http://www.landroverresource.com/
its the workshop manual for our trucks. will explain everything.

 

thx Ed
