Really-- 3 mufflers,rather than figuring out why
the first one went

I guess you asked for a new muffler & no other
diagnosing, as to the cause

Now after 5months-- maybe someone on the internet
could guess

If the fuel pump check valve has failed, it will take longer
to start, but only after a long sit

You have a problematic fuel pressure regulator under the
intake manifold, that could be leaking & dumping raw gas
into the exhaust

Buy now your exhaust converters are ruined by you
procrastinating & all the raw full

    procrasting is not the word I have been trying to find someone who knows what they are talking about .Would you know about how much it would cost for repair

  • Anonymous Dec 07, 2012

    You can go to Rock Auto.Com for parts prices I can't really tell you what is wrong no one can you need the vehicle to do some testing. Find a repair shop you feel has been around for 25 years with the same owner That is what you need

    Thank you very much. It seems like everyone has just been quessing , I have went online and found the part ,it could cost just over 125.00

sounds like a fuel management problem. the catalytic converter is getting to hot due to tryin to burn off the excess fuel not burned. causing the muffler to overheat get it scaned at autozone for free. sounds like a o2 sensor runnin lean dumpin more fuel. or a bad mass airflow sensor good luck

SOURCE: Won't start after sitting 12 or more hours.

thats going to be in your timing...if you blew the muffler up then the timing is way off or its time for a new timing chain and gears

SOURCE: sounds like a plastic bag on the muffler.

Possibly a loose heat shield near the exhaust rattling.

Sounds like you have to much gas going thru the throttle body. When you put your foot on the gas it opens the airway and lets air and no gas. The black smoke is unburned gas. Replace the throttle body and you should be good to go. It could be the fuel sensor also, telling the pump the wrong info.

SOURCE: vehicle is turning over but

Your fuel pump probably stuck. Use a wood bat or rubber hammer to tap on the tank. Have someone turn the key to on (not crank) with your ear by the tank to see if you can hear it hum for 1-3 seconds. Next replace the filter to remove any water in the lines, and don't forget to put some water remover and octane booster to "fix" the old gas that has gone stale and sucked up water.

Alternator tests good wont charge battery


I'm sorry to say it could be the computer.
The computer controls idle speed as well as alternator output.
If the check engine light is on you should get it scanned for trouble codes.

It is almost definitely a bad alternator, but could also be a limited number of other things. A bad battery terminal could cause this problem as well or other loose or corroded connections. As for your 12 volt reading on the alternator, I should explain a little about electricity. If electricity travelled down a highway, the number of lanes would be the voltage and the speed limit would be the amperage and the wattage would be lanes multiplied by the speed limit. 12 lanes travelling at 2 miles per hour aren't getting anywhere fast. Also, a car battery's charge voltage slightly above its' output voltage, so it should be roughly 13.4 volts up to about 15 volts.

If your battery is years below you need to change it to new one if this happen the voltage become low mean your the battery plate is getting week, or the water becoming low, battery wont last for 3 years you are lucky if you reach that time. For better performance battery life is only 1 and 1/2 years and be ready to ready replace it soon

Every once in a while the battery is dead


sounds like you have a short somewhere if it sits for a few days does it loose power and not want to start?
if you start it every day (or once every 12 hours and let it run for about 20 min) is there no problem?? if so you probably have a short somewhere that is draining the battery slowly

It could be the alternator but is most likely the low battery. Best to start with the simple things. to check if its the battery disconnect the low battery when you stop. Check the low battery then after 12 hr's check it again if it has lost power then that's the problem. If this does'nt sort it repeat the process with the main battery as although its good when you have checked it I can still loose power when sitting. If it is not a battery problem check the under bonnet light, boot light and glove compartment light dont stay on when closed.

Put you a really good battery about $90 or more. Try interstate MTP-65 or MT-65. I dont work for them but I'll bet it'll fix it
