Cars been running great and all of the sudden it started well, either shifting terribly, or misfiring @ every shift. Right now I've got codes P0202 & P0201. Had this problem happen once before and ended up replacing the injector. When that didn't fix the problem I cleaned the connections and the problem went away. Skip to several months later & I'm having the same problem but with 2 injectors this time. I'm a bit miffed & confusedso any suggestions would be appreciated folks.
