I have noticed a stronger exhaust smell recently in my 95 coupe interior. Happens when windows are up or down. Weatherstrips on rear hatch appear in good condition. Recently replaced cabin filters (2). Hatch does not rattle or leak water currently but rear roofliner shows some water damage from previous owners. Have read a number of posts on eventual repair of the hatch frame/glass issue, but wondering if replacing the hatch glass gaskets, weatherstrips, etc, is the place to start.

I've owned three 944/968 series cars - so been there done that with this problem...



It can be a couple of things:

1. Fuel overflow carbon filter is saturated because the previous owners kept the tank full to the brim...

2. You have a pinhole sized air hole somewhere aft of the front seats.

3. Hatch latches may not be adjusted properly - the hatch then doesn't seal corrrectly.

4. The hatch seal needs to be replaced.



Easiest way I've found to trouble shoot this issue is to pull all the carpet up in the rear hatch area, make sure you can see inside the rear wells, and then when it's real dark out, with you laying inside the rear hatch area with the hatch closed, someone with a real bright flashlight shines the thing everywhere around the rear of the car.



Every leak I've found I found this way...



Then when you find the hole, plug it up or adjust the hatch latches or replace the seal.



If you find NO LEAKS, then you have a problem with the carbon gas canister, that's no fun and a ton of money to replace.

I spent months dealing with this. Agree with checking the rear hatch locks and pins. Mine would close normally, then one side would start to lift at speed, allowing gobs of exhaust smoke to get into the cabin. The culprit was that the hatch lock and pin on the left side had worn out and were no longer able to lock down the hatch adequately. I also replaced the rear hatch seal for good measure, but making sure the hatch locks and pins were secure was the biggest help.



Another way to check this is to place a flashlight in the cargo hold at night with the beam pointing towards the rear of the car. Standing outside, look around the seal to see if you see any light getting through. Then gently start to lift up on the hatch (with it still closed) to see if gentle pressure dislodges the hatch pin from the lock. Mine did and it was the major source of the problem. Let us know how it goes.

Another item that is often overlooked are the hatch shocks. If you replace them, you'll notice the hatch will shut more tightly and rattle less over bumps.
