I have asked before about the check engine light which goes on from time to time with reduced power on on long stops with engine on.

the computer scan code is p1239, I still have the problem and I have tried almost every thing but now the check engine is on all the time and when ever I stop reduced power lights as well, I have noticed that when the car fuel level is low (fuel light is on) check engine light goes off for some time.
any body have anu idea?

That means your fuel pressure is high, this is a direct injection system. Check your fule filter, battery condition, and fuses. Anythign other thatn that take it to a pro as there are several other steps that need to be taken
