Hey guys I'm new on here and Well as the title says I'm currently having some issues with my 4age 20v blacktop.

I got my 1986 corolla a while ago and if any of you have driven in Hawaii you know there is a lot of pot holes. One day I had the bad luck of hitting one and ever since then when I cold start and I start driving my Rpms start jumping and kind of feels like a cut in fuel but I'm not to sure. It also does this while warmed up if I'm revving up past 3000rpm. I asked a couple of guys, but they couldn't figure it out either.

I also changed the fuel pump to a supra pump and checked vacuum lines (no leaks), iac?, didn't check fuel regulator yet, sta wire is good. I'm not sure what it is but I need to fix it. Thanks for reading.
