I have an 04 with 3"turbo back. I got a perrin CEL fix. Then like 2 months later I started getting random CEL. I have just started to notice that the CEL comes on when im close to a 1/4 tank of gas, but goes away when I fill up. Could this mean I have a Fuel system problem. i.e fuel pump, pressure regulator.........any input would help.

 

Damn no love wish ppl knew what my problem was......

 

Go to Autozone or the like when you have the CEL. Have the code pulled and see what the problem is.
