Like the title says i need help bad. You see my engine and engine bay were dirty so i decided to clean them. So i got some simple green and the old water hose and clean it real good. But the bad news is that i didnt cover anything. So now its running like crap. It is hesitant, the rpms are acting up and its not running the same. It doesnt take off when i punch it when im already going fast like it used to.The check engine light came on, so i disconected it and it stayed off. But coming back from a friends house it came back on. Could it be something electrical? The fuel injectors or the fuel injection itself. What could be the worst? Will it go away and should i not worry about it like my pops says. Any help of advice is much appreciated. Thanks in advance, ed.
