Ok, so i posted about a month ago. I said i had problems with my 93 SE. A lot of people said it was my MAFS because the car wouldn't go over 2500 RPMS, it backfires, and it throws and engine code. So i replaced it recently with one from a Junkyard. The car at first startred up and jumped to about 5K RPMS, then all of a sudden the car went back to doing the same damn thing. Help again

 

it could be your AIV unit

 

it could be a clogged cat.
