In two days, I have managed to stall my car twice and I drive an automatic. I believe this to be a problem related to my VI and FPR. I say this because if I let my car idle for 10 minutes or so, my CEL comes on and claims both banks are running lean. Well, I double checked my vaccum line to the FPR and as it was T-ing from another vaccum source, I decided to give it a dedicated vaccum source, hoping it would solve the problem. Nope. Anyone have any suggestions?

Aftermarket FPR or the stock one?
Got a gauge, tap into the fuel line and see what it's running at.

What type of gauge are you talking about?

Fuel pressure gauge, it ties onto the fuel rail.

i had the same problem kept getting running lean codes even at idle. i checked everything hoses gaskets still nothing. then i changed my 02 sensor and walla it was fixed. even though i didnt throw a 02 code it seems it was on its way out. its been over two months and no codes at all.

O2 sensors have less than 15K miles on them. I changed them all at 65K and I have just over 79K on the car right now.

start looking for a leak then.do you know if this happens at idle or wot. i have a carchip that told me exactly when it was happening. the only other thing is fuel related, check fuel pressure and injectors.

It happens when I take my foot off the gas. The times it happened, I was cruising (10% throttle) and took my foot off the gas and coasted
