Issues: Hesitation & bogging
1994 Olds Cutlass Ciera *, 3.1 v6 133,000
Things that have been done:
Coil packs replaced
ICM replaced
TPS Tested (OK)
It get just warm and starts to act like it is starving for gas, does not matter how far i push the pedal down. The MAF is also new, clean air filter, egr port is open not clogged.
not much else to do except replace the Crank position sensor, the cam sensor, the Fuel pressure regulator.
I have not seen a fix for this anywhere, Help please

Do not replace the crank position sensor. When it fails, it shuts your engine down. It will not cause what you describe.
Pull the vacuum line off the fuel pressure regulator and smell the line for gas. If you smell gas, replace the regulator.
When is the last time you changed the fuel filter?

Should be no smell of gas while its running. Does any gas spit out of the regulator when its running?

SOLVED Thanks for the assistance, The Fuel Pressure Regulator appears to be the problem, Replaced it and let the engine get hot before taking it for a ride. 20 miles no problem...
