It's possible the broken muffler could cause a misfire. Your engine is expecting a certain amount of back pressure from the exhaust. If that back pressure isn't there things may not ignite properly. It's also possible that the hole is messing with the expected gas ratio in the exhaust and the emissions control system is trying to correct it by changing the fuel/air mixture and causing a misfire.

1999 Blazer ZR2. Replacing muffler and tail pipe. Can not pull apartl flange on muffler and exhaust pipe. Bolts broke off and still can't break. Don't have air impact chisel. Would heat help.

The auto store probably sells a big chisel and a 4 lb hammer? If your going to replace anyway, use a hack saw. In my younger days, I've cut many a tail pipe with a hack saw. So a new muffler and tail pipe will have new flanges? I can't see anything from here.

How do I replace muffler in 2002 grand prix se?

if the exhaust is all one piece meaning no joints/connections then cut the old muffler out by cutting the pipe in front and behind the muffler leaving enough pipe for the new muffler to slide around the exhaust pipe and then using muffler clamps clamp the pipes in place on the muffler until its tight.

Sounds like your catalic converter is trying to stop up. When you drive it this heats up and causes your car to vapor lock and quit running you let cool down and it will start back and run for a while. You can take it to a muffler shop and they will check it for free. This could be any number of issues but this is where i would start.Best of luck to you, Thank's for using Fix Ya.

When I first crank it up in the morning it runs good. After it has warmed up, it wants to die at an idle or won't crank back up unless I hold the gas pedal down.

Sounds to be your catalic converter is going bad, May take to a muffler shop. Should be free to check this, Good luck.

Very common problem with the muffler strap(clamp) breaking. It can be bought at any auto parts store & is easily replaced. It wraps around muffler & slides into a rubber mount bracket.

You have a plugged catalitic converter restricting exhaust flow. Call around to muffler shops and price around and replace.
