It seems like my mechanic was able to finally fix the overheating of my car after having to put in the new heater core and driving the car for a good 40 minutes on a 90 degree day.

So when I take the car for emission's they tell me that I have to fix the exhaust cause there were holes all over the pipes (I'm guessing from sitting in the garage for 14yrs). So i go to a muffler shop and just restore the whole exhaust. Got me a flowmaster series 40 and it's was sounding nice. I drive the car for another half hour and I love the sound so I just decide to wait till the next day for emissions.

So today when a friend of mine comes over to hear my new exhaust, I turn the car on while it was parked in the garage, and it was loud! The thing is that two minutes after the car was on I notice the choke light was on as well. I quickly turn off the car and when I do the engine sort of startled. Now I'm sort of scared to turn the car back on.

Could it because of the new exhaust?
