My Service Engine Light came on yesterday. I checked the code and it says I am running lean. I am not running any engine management or an AF Controller. I do have a manual boost controller (set at 19psi), HKS intake, and exhaust. All of these parts have been on the car for more than 3000 miles. I had my 15000 mile service about 800 miles ago. Current mileage is 15980. I have disconnected the battery twice but the light comes back. Any help would be appreciated. Thanks

 

What is the code #? Is it a P0171?

 

P0171, I believe is the code pulled when we checked it.

 

Check all vacuum lines, and check all intake piping to make sure nothing is loose.

 

Oh yeah, make sure the BOV didn't pop off either lol. That will throw that code as well.

 

checked everything I could see without taking anything apart ie bumper and undertray. Everything seems to be in order.

 

can I still drive my car till I can get it to the dealership on Tuesday? Also this morning when I started the car it would drop RPM'S and shut off a few times before it warmed up (about 5 min).

 

Just for kicks go out and see if the I/C connection at the throttle body is connected firmly. You'll be fine driving your car to the dealer. Just don't go crazy on the RPM's and boost.

 

I turned the boost down to about 15psi. The connection at the throttle body is good to go as well as the intercooler.

 

fixed the prob. Turned uot to be a loose hose after all. Thanks for everyones help. I appreciate it.
