I purchased the Actron Computer scanner which it told me that Injector #5 was bad, so I went and replaced it with a new one. I am now getting 2 codes P0300 and P0404.
My car will drive no more than 30mph, but after it get's warmed up it will drive normal, well some what. Once it's warmed up I can get it to go over 50mph, but the car shakes and hesitates to go faster.
Has anyone encounter this issue? I am thinking it might be my catalyct converter, but I don't want to replace it if it doesnt need to be. PLEASE HELP ME.
