2000 buick park avenue quit running.changed fuel filter and pump runs now but wont idle any suggestions?

Idle issues usually stem from the EGR valve being bad or the EGR passage is clogged with carbon deposits from the exhaust.

1991 buick park avenue starts when gas petal is pressed but dies once you let off gas petal

There could be several causes for this problem but from your description it sounds as if you car is not getting enough gas. This could be caused by a plugged fuel filter. Another cause could be a fuel pressure sensor. General Motors has had a lot problems with this in the past. One quick way to find the problem is to have the vehicle hooked up to an analyzer and see what code is displayed. The cost of this is usually around $65 or slightly higher in some areas plus the cost of the parts. If it is a fuel filter the part is relatively cheap. Analyzer prices are higher. Make sure your mechanic quotes you a price before having it repaired and also ask him for the code number from the analyzer. This will usually keep him honest.

1991 Buick Park Avenue sputters at random, stalls-egr problem?

I would look at the Map Sensor or the O2 Sensor then the EGR Valve. As far as I know all vehicles have EGR valves. Get the Haynes Manual on your vehicle for location and replacement steps for all of these. It could also be a Throttle Position sensor or clogged or malfunctioning injector units, the Haynes manual will assist you in isolating these.

Where is the EGR valve on a 1991 Buick Park Avenue 3.8 ? It is not on the intake manifold on the '91.

Here is the steps to remove and replace it with a hint of where it is...

Removal & Installation
  1. Disconnect the negative battery cable.
  2. Remove the decorative cover from the top of the valve.
  3. Disconnect the electrical connector at the solenoid.
  4. Remove the 2 base-to-flange bolts.
  5. Remove the digital egr valve and discard the gasket.
To install:
  1. Clean the mating surfaces of the egr valve and its mounting surface.
  2. Install a new gasket and the digital egr valve.
  3. Install the 2 base-to-flange bolts. Tighten to 22 ft. lbs. (30 Nm).
  4. Connect the electrical connector and install the decorative cover.
  5. Connect the negative battery cable and check the system for proper operation.
If you have a VIN "L" in your VIN number, you do not have an EGR valve.

Otherwise, it should be towards the front of the the diagram it is labeled #11. To post it bigger, I would have to email it to is too large to post at LARGE view here.
