Ok I installed the Wideband exactly how I installed it on my buddies car his works perfect... but on my car it doesn't heat up on the free air test, and the LED just stays solid red and the gauge is on full RICH 18. If I remove the gauge wire it drops down to 8... I dunno wtf is going on and I can't figure it out so if anyone knows let me know thanks.

Pm miguel barros, i think he used to have one before he tookk off on us.

make sure your grounds are good, and apparently they have to be seperate (I think thay have to be 3 inches apart). dont know if that would make a difference but mine worked fine.
