Default PO201 thru 4 Codes

We've had lots of problems with keeping our latest PT running. This one is a 2006 and was showing PO201 thru PO204 codes indicating the fuel injectors needed serviced. Took the car in to the dealer yesterday for injector servicing and we still see the same codes this morning. What to do now? The PT starts and runs okay unless it is parked in the sun on a hot day ( this is in Florida) and is difficult to start or keep running. Excepting suggestions on what to do.

Did they check for proper fuel pressure at the fuel rail ?

What they claim they did: "Flush out fuel injectors, R/R throttle body, disassemble, clean reassemble with new gaskets, and make all necessary adjustments."

The key here is the problem occurs on a hot day. Could be that the fuel pump is clogged or failing thus not providing enough fuel pressure and the hot weather compounds the problem. They need to check for proper fuel pressure.
