A hole on EGR pipe? If you're sure then there must be significant drop on the vacuum line. The engine must shaking while idling. This may cause by improper type of hose is used on the EGR line.

How to remove intake manifold for 1997 pontiac grand prix

You have to remove anything that is connected and in the way of the intake. Remove the fuel rail, the EGR valve and supply pipe from the manifold, the map sensor, the vacuum for the fuel pressure regulator, the alternator and support bracket, the water pipes for the throttle body, and the bolts that hold it down.

I have a 2001 grand prix gt 3.8 down to 15 mpg possible egr valve bad how do i check it has no power and barely climbs hills

Catalytic converter may be clogged. If engine light is on use the ODB-II code reader to find code. OR you could try disconnecting the cat from the Y pipe. Only do this if you can free up the bolts or have new bolts to replace broken ones. If you separate this part of the exhaust, fire up the engine take for a drive. If you have all power back then thats your problem. This experiment is loud though but worth it.

Leaky fuel fill pipe

Is it rusted and leaking,only when filling at gas pump? Check where leak is. eg rubber hose or pipe. You can remove and solder pin holes. Kind of old to look for a new part.

Standing in front of the car looking at the engine bank 1 is the cylinders on the front of the engine. These are cylinders 1-3-5. On the rear is bank 2 cylinders 2-4-6. The O2 sensor is located screwed into the exhaust manifold or the exhaust pipe on the front of the engine.
