How to remove the rear quarter panels from a 1993 Pontiac Grand Prix SE coupe? Will any cutting be required?

There are some awesome adhesives on the market. I am thinking about one for boats and just remember "1500" as part of the name. With marine products you will not have any problems with moisture separating it so car washes will be okay.

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

There is no fuel pump cut off switch in General Motors vehicles.If you don`t have fuel pressure or the pump is not running you have to check the fuel pressure with a fuel pressure gauge.You can check the fuel pump fuse and make sure it is good.Hope this helps.Good luck.

You will have to remove the backseat. First the bottom part, it has two pull cords to release the seat. Take that out. Then for the back part, you will have to remove 4 nuts (2 with washer looking things attached and the ones holding the seatbelts) at the bottom of the seat. After removing them, where you had removed the seatbelt nuts, you will have to remove the seatbelt peices. Once that's done, you will have to pull the seat out and up. Behind that, there is 2 round button anchors, which you will have to pull out. Once those are removed, the whole back peice comes out, exposing the rear speakers. They should be 1/4 bolts holding the speakers in. And if you are modifying (not using stock speakers), you may have to cut they wires to replace the speakers.
