Help please chasing engine codes!!!
I have a 4.7 2002 ram single cab
I need to have no light to pass my emissions that is due.
First codes was fuel injectors and cylinder miss fire so I changed the plugs all eight , next code was two fuel injectors so I bought that purple cleaner that I was recommended. And cleared the codes. I am getting different ejector codes and ignition codes, are these from that stupid cleaner or is my ECM shot? Oh yeah i also changed my throttle position sensor. Miles are 181000.
