Starting off, this Camry is an awesome car, and it gets better gas mileage then my 96 Civic I had before it.
I just recently replaced the alternator in this car, and knowing the car's history, that was the forth (including the original) in about three years. I don't mind replacing it, because I have a life time warranty, but fixing this problem is better. The helper at the place I got it from said it might be my starter putting too much amperage (voltage?) into the alternator, but he also tagged on that the alternator would have croaked sooner if this were the problem. I haven't done much snooping around in the engine because my knowledge of repairs is basic at best, so someone's "expertise" is needed.
Engine noise: The car has trouble starting (more so in winter) so I have to give it gas before it sputters to life, after that the car runs fine at idle. Taking my friends advice I got some fuel injector/carburetor fuel treatment to fix this problem. It worked on the first start after putting it in but after that it was the same old thing. I ran the car for about a gallon's worth of use (after treatment) and after sitting at idle for about 10 minutes one day it started to run very loud when giving gas. Now the car sounds like it doesn't have a muffler, even though I know it does and it doesn't seem to have holes anywhere in it. the RPMs stay within their normal zones and the car doesn't buck or anything unusual.
Is this a dirty carburetor? Is it even a carburetor problem?
