2001 4.2L v6 running lean on bank 1 5 speed manual
Hello all,
My truck recently threw an engine light and the code was for running lean on bank 1 and speed sensor on front driver side missing. I am more concerned about the lean right now. At first I could not notice a difference but I used sea foam and cleaned out the engine and injectors just to be sure. (Smoked like no other!) But there is still something not right, it feels like I have turbo lag when I first step on the gas and I can hear what sounds like air getting into the engine when I accelerate. Is this just a vacuum leak or could it be something else. I am all out of ideas on this one. Thanks in advance for the help.
