Ok I have done some work to my csvt and now I'm having major power issues I can't figure out why it just is not making any sense to me. I did a egr delete cleaned the upper and lower intake replace the gaskets oil change. Before I did those things she ran like a charm now it barely wants to go over 40. If anyone has had this problem please help me out. I need to get it running good again so I can sellthe motor for my 3l. Thank you in advance
