What is the solution to lean fuel/boiling swirlpot on LS7

[bluesatin]

Hi,

Just been out for the past couple of hours and got caught in traffic for 20-30 mins. Car started to misfire when the traffic cleared. Switched to other tank and all ok for 10 mins then started to misfire again while in built up area eventually stalling and not starting. Thanks to a passing tow I made to a safe place to park up. After 20 minutes the car started fine. OBD2 error code was lean on bank 1 and 2! I have an LS7 with standard factory install including swirl-pot. Any ideas on how to stop this?

thanks

Thanks Mark and Paul. Will check through some of the advice first and set up a temp gauge in a few places.

It is worth speaking to Charles Dunn as I think he has now resolved this. Issue is the fuel gets way too hot in the swirl pot. Try insulating everything close to the exhaust as first pass,
