I replaced the o2 sensor and it won't even power brake on a dirt road... its not popping any other codes

 

it's a heavy vehicle with under powered rear gears and other stuff that limit power comin from factory. get the intake, headers, exhaust, servo and tune then you'll be set

 

I replaced the o2 sensor hoping it would solve this power loss.. It wont even power brake on a dirt road.. Push brake punch it.. Rpms stick at 1500 and its got no power.. Let off brake and stay on gas and it still doesn't spin, until you reach about 3000 then it starts to burn them.. Its sad

 

Sry for double post.. I didnt think it went through. But I would really like these things for it. I just remember when I bought iti could burn the tires slap off it from a redlight or stop sign

 

it's not throwin any other codes? and get them things i told you about then you should be set man. just try not to fall in the hype of all the programmers and chips and little things that say they add so much horsepower...most of em are scams. kinda like throttle body spacers on new vehicles. carbed motors they worked great, not so much in today's electronic trucks

 

Ok I'm getting a p0332 knock sensor code now.. is this killing me?

 

yessir...it is. I had the same code and noticed a big power loss...replaced it and it's runnin great now..it's not hard to do, there's two of them under the intake manifold. just pull the manifold off and replace the sensor thats bad(usually the one thats closer to the back of the engine)
