Hello everyone! I am here in hopes to learn from you how to better tune the Jeeps that come into my shop equipped with the Howell EFI systems. Most are fine just as the system comes but I have one "special one" here that is giving me all kinds of problems I hope to solve for this customer. Thank you in advance for your help. - John

Start a thread in the GM EFI section and give us some details of the vehicle with issues.
