Should I take my max to a garage to tune up my engine? Or a dealer who would know more and charge me too much.

Or can I do this myself?

 

do it urself and feel proud when u floor it

 

I've been trying over a month now. I really hate only getting 260 miles per tank.

 

"do it yourself, as long as you have a semi-decent set of tools you'll be fine."

 

I still need to do an o2 on mine then maybe I'll get over 13 mpg

 

could this be why i have shotty gas mileage, and a noisy engine

 

that;s probably a leaky exhaust, which can also hurt the o2 as well

 

how can i trouble shoot a leak, just start it up and check all the connections?

 

you could put in some sea foam and look where the smoke comes from and there is your leak. You'll clean the inside of your engine as well.

 

For a the longest time I couldn't set my timing correctly. The timing had to be at 30 just so the AAC would provide enough air or something to that effect. After driving on 11mpg for a about a month, I changed the 02 sensor and VOILA! I set the timing to 20 idle and it's all good. We'll see how it good it is on gas now.

The aac still needs adjustment because starves for air at 5500. Should i turn the AAC clockwise or counter to fix it?

 

I changed my 02 today. We'll see what happens.
