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 1995 Pontiac transport light go dim or off and on when driving at night also low battery replaced alt about 1 or 2 years ago

vehicles: Any with headlight(s) going dim/off (day or night).

Even if your battery is barely strong enough to start the car (that's all a battery is really needed for anyway - once started, your TranSport will run without a battery), the alternator should provide enough Volts/Amps to light the headlights fully and steadily. The symptom you're having tells me that your vehicle has either a problem with the alternator or the voltage regulator which is an integral component of the alternator.

Secondary items to check: loose wiring harness to one or more headlights.

Tertiary items to check: possible beginning of failure in headlight switch.

In the US., one can drive to an Advance Auto Parts/AutoZone/Pep Boys and get a free "charging system check", which is done without removing any components of the car. You simply turn on the car and the technician checks the car while it idles in the parking lot. This check will tell you if you have a weak alternator.
Also, a battery can be disassembled out of the car and load tested in an in-store battery tester by the same auto parts stores.

For your next posting (where you may be asking how to replace the alternator), look up the 8th digit of your 1995 TranSport's VIN code:
Select the engine of your 1995 Pontiac Trans Sport:
6 cylinders , VIN "D" 3.1L TBI
6 cylinders, VIN "L" 3.8L SFI OHV

My pontiac transport cuts out i replaced the fuel pump and the battery goes dead after awhile new battery now while driving it dies like a fuel problem new fuel filter too please help

Check the alternator for voltage output,worn belt and belt tensioner.

A health alternator should be produce 13.6-14.8V.

Any less it will put a drain on the battery.
(example: fuel pump,fans and lights)

Base on what you changed already,I recommend you to

1)inspect the tensioner wear indicator (two arrows,lines or dots) if they coming close the it's time to change the tensioner.

2)check the for worn belt. Look for cracks on the belt.

3)charge up the battery and monitor the voltage.

4)get the alternator check.
Most alternator can go up to 100,000 miles.
Some auto part store has a portable battery + alternator test.
