I replaced my O2 sensor and no change. I replaced the ground above the O2 sensor a while back so that's good. I also replaced the coolant temp sensor a while back so that's not it.

If I play with the MAF sensor connector, the engine will kinda surge and whatenot for a second. Nothing happens when I do that with the TPS connector.

I ordered a TPS sensor online for cheap so we'll see if that changes anything...

Also, I replaced all my vacuum lines a short while ago, so I doubt that's the problem.

I took out my AIV and EGR too...
