[heater]

I have a no start hot issue ,it has stall on me at idle then won't start until cooled off. hpop has been changed as well as ipr, icp, and all injectors. I had codes 2290,2291 come up , ipr,icp and ficm all check out .I know I have a leak somewhere but can't hear it with air test . Need some ideas of what else I can do to find this leak .can the hpop develop a leak from o-rings and leak when it is hot

Thanks in advance for the help !

Is it an early or late '04?
