Got a 2.0 vw beetle with the AQY 8v engine

Got fault codes lean and rich bank 1,

Ticks over rough and won't rev up

New plugs, coil, fuel and air filter's

TB seems okay and inlets clean

Can't find any vacuum leaks

Fuel pump works and fuel gets up to the FPR

Bit stuck now and only have Delphi diagnostics as vcads lead is at my parents

Any ideas where to look now?

Thanks danny

Checked the MAF or MAP Sensor?

 

If it has a MAF sensor, check for splits or tears in the intake pipe inbetween the throttle body and the MAF. this will be Un metered air which will mess with the fueling.

Still not cured this!!

Had new leads, new FPR,

100% fuel issue as picks up neigh on perfect when i spray a solvent into the air box ( I know I know bad practice )

Had the pump put the tank and cleaned it all, still no better

Thanks dan
