hey guys just wondering if anyone is having a problem with their fuel injection system...got these 2 codes couple days ago. The computer says Bank 1 and 2 systems are too lean.

I believe i had one of these codes awhile ago when i put on the 00vi...and the code went away.

recently i took the emu back out since it was a defect and solder all the wires back together to get the car running again. Car ran fine and was trouble code free till after 2 weeks later the P0171B and P0174B....any ideas? thanks

 

i guess nobody...well eu going back on the car this weekend hopefully..

 

Check MAF and vacuum leaks. Usual causes

 

i took the breather off the car n put the intake backon..just did another oil change and changed the main cat.....car idles better now and codes went away....something still rattling under my car.figured it was the main cat..but on 1st n 2nd gear i can hear something rattling...
