Fuel trim problem

[R 20vt J]

Scanned my car and it threew up p1128 code long term fuel trim, bank 1- system too lean.

What could this be? is it a leak somewhere?

Also my electric window drivers side switch was kind of dodgy and i had to press it hard to get the window down but now it fell through slightly and wont work at all. Is it easy enough to take the door card off and push back into place?

Cheers Ross.

cant help withthefuel problem..but the electric window thing is easy.

the bit of trim around the handle pulls straight off, but have the handle to the open position first.

there should be a screw holdingthe other bitof trim in place, unscrew it and then that should pull off with a bit of a tug.

the window switchwill just click back into place

Did you change the maf mate? When i scanned my car the maf reading was at 0.415 and i am lead to believe it is 0.3 roughly?

Cheers!
