I tried everything but does nothing but now it's has a rough/low vibrating idle and idk if it's ticking cause I have a straight pipe so it's loud and deep but will stall after a couple of min I give it gas and it stops a little but oil gauge is rocking back and forth it stay in the white lines but can see it moving idk what it can be? And code 37 is the only thing popping up but when it stalls oil lamp light comes on...first time I read codes 51 & 37 popped up bu now 51 - Fuel lean went away it's just 37 but messed with the TCS and Nuetral Saftey switch but nope now I'm lost I tried everything and can't find anything that explains what's going on...

 

You already have a thread going for this. Just bump that one, don't start a new one.
