Hard starting have to give it gas, seaching for idle and dies out. Scanned ECM no codes? O2 shows rich,TPS sensor stays at .41 Volts the IAC seems to be working it keeps adjusting for proper idle. I am going to assume its the TPS. The manual says it needs to be adjusted. Anyone know the procedure or if this is the problem. Also manual claims 3800's do not have EGR valves. But it sure looks like one on this car because I originally thought that may have been the problem.
Any thoughts anyone?
Thanks

No EGR? It's there, your manual lies.

Adjustment of the TPS is done with the voltmeter, or scanner connected (KOEO), to see the voltage, loosen the 2 mount screws to set to required vlolts, but you're in range I believe.
