Ok, so here is where we are at....

Replaced the o2 sensor...in that found out that there is no catyliyic converter on the car. Someone has replaced it with a strait pipe. I'll get that delt with later. After taking to muffler shop to make sure that something didn't get messed up when that was done the mechanic said after looking over the car that there is def a vac leak. So I started poking around and discovered that the air filter cover is all busted down the side. there is a chunk that would complete the seal around it. I have a new one ordered online. In the mean time, Autozone helped me put a seal around it temp. once it dries we will see if that helps with the RPMs. Here's to hoping it was that simple!
