Hello I am new to the site and it seems like someone might be able to give me some suggestions. I have a 1995 Silverado and I have lost a lot of power and my gas mileage has gone down considerably. I also was getting off the highway the other day and my truck just shut off. I was able to restart it but obviously somethings not right. I am going to get a diagnosis done but I was wondering if anyone might be able to tell me something so I have 2 references.

Thank you

 

is ur service engine light on?? how many miles??
