??? Ive been trying to get rid of my hesitation problem and wanted to try unplugging one of the O2 sensors to see if that maybe would help I heard it would keep it in open loop which is when my car runs good but when it warms up it = crap.. im going to bring it in soon to get the plugs wires filter and O2s changed if this works soon, any advice on unplugging the O2 sensor? and what exactly should I expect to go wrong if I have the O2 unplugged? anything? my car is completely stock

 

If you're talking about the pre-cat O2s, then it will run like dookie. If it's the post cat, OBD2, you'll just get a SES.

 

I have a 94 so its a OBD1 do i have a post cat O2? Thats the one I wanted to test with
