Barely runs when cold (any outside temperature). After it runs about several minutes, if you could keep it running, it then runs fine and takes gas well.

Don't have VAG codes, only OBDII ones:

P0171, too lean bank one,

P0174, too lean bank two.

Changed coolant temp sensor, no difference. Fuel running pressure about 60 psi. Sorry my software won't allow me to get VAG codes. Any ideas?

Thanks!
