Pontiac Sunfire

Why would a 1996 Pontiac Sunfire make a strange popping noise once in a while and will run rough or even stall as the engine gets hotter and hotter especially in the summer?

Check the cellinoid (sp?). I just had the same problem on a 1995.

I have a 96 Sunfire with the exact same problem. First I changed the plugs, the plug wires, the distributer cap and the control module. Then I changed the fuel pump, fuel filter and the fuel pump regulator. My car is still in the shop and they are stumped ... and I am broke.

Make sure the cooling system is working properly, kinda sounds like its overheating real bad.

I went through these same issues with my 98 Sunfire and called the Better Business Bureau to complain and GM extended my bumper to bumper new car contract to 7 years (which is up now) and they continued to fix everything they could think of - all covered under the warranty. So far this summer it seems to be okay - but I am planning on getting rid of it soon for fear it will return since it is no longer under warranty!

Mis-timing. If you're off by a notch on the belt it can cause wacky things to happen.

Check your cam or crank sensor, if its bad it will start but run erraticly after a certain rpm kinda like as if your converter is pluged.

How about the cooling thing? It is overheating. I had the same problem with a 2001 Dodge Intrepid.

Did the old radio have any sound? Do you get a strange code on the radio display indicating that you are locked out? You might have to pull the radio back out and make sure that the speaker connection plug is plugged in securely.

Because lady gaga is strange. Listen to her music. Especially the song in question. Obviously, you do listen to her music. But I mean, ACTUALLY listen to it. Why does it surprise you that she looks strange?

african music would seem strange, unattractive and difficult for us to comprehend especially when we are used to the western orientation and notation of music

I'm told: clear still weather, a popping feeling in your eardrums and a strange colour in the daylight from the surrounding tall clouds. Get back under shelter.
