Question about Dodge Charger

1 Answer

06 charger, 5.7 Hemi 45,000 miles. Running great with no problems. Stopped to fill up with 93 octane gas. After filling up, I started the engine and it was running rough and making a knocking noise. I took it to a local pep boys and they said it was severe engine problems. The key to this is that it never made any noise, the check engine light never came on. The car is in great shape and never has made a noise or been missing or anything that would need to take it to the shop.The guy pulled the plugs and indicated they were wet, thus saying that the piston rings were bad. I saw the plugs and they were wet but not exessively. they were a little burnt but looked like it was gasoline instead of oil. To me it is a case of bad spark plugs. What do you think?

Were you running 93 octane before?try new spark plugs.engine that size shouldnt be worn out in 4 years..get it put on a tunescope,an ETOC one[ETOC every turn of the crank]it should tell you a few things.lots of money for a new engine,so check things out first.

I have a 2001 vw jetta 1.8L turbo , engine code AWD if that's helpful,, 5 speed manual transmission.... Car ran great for over 20,000 miles when suddenly while driving it would die for about 5 seconds...


Did the plug wires get changed with the plugs? Try this..... Get a squirt bottle and fill it with water. When it's dark outside start your engine, lift your hood and mist the water over all the plug wires for a couple minutes. Keep it dark so you can see if spark is leaking from your wires. Also check your fuel filter, if you havnt already.

My honda accord ex 91 is running exellent since i changed the ignition wires and spurk plugs. it has 107,000 miles, manual transmision. for more power and gas saving, what kind oil motor and gas should i...


With that many miles there is no point in putting synthetic oil in the engine because it will probably be too thin and cause the seals to start leaking. Keep the oil changed regularly (every 3000 miles) and use a brand name 5W-30 grade oil like Mobil1 or castrol. As far as gas goes I would put a tank of high octane gas in about once a month. You can try using high octane all the time but check your mileage per tank on the regular grade and then after you've filled you car about 4-5 times with high grade so you can see if it really is making a difference. Also check your owners manual to see if it recommends higher grade gasoline.

I have 97 cavalier not sure if i had gotten bad gas think so drove over 500 miles no problem went to different little gas station 40 min later driving started to have problems wanted to stall when trying...


use a tank of high test 93 octane, had the same type of problem with my 97 cavalier 2.2 ltr motor. If I would shut the car off for a few minutes and then restart it, it would drive normal again for a while. This would typically happen on hot days especially if you are sitting in traffic. A fillup with 93 octane gas for some reason would seen to solve the problems for a few weeks even after filling up with normal low octane 87 gas after the high octane fillup. I found no reason for this behavior and I am a mechanic all I know is that the car hasn't done this for me in some time and no repairs had been done, just one of those weird things cars do once in a while. mine has 277,000 miles and still running

Having problems with accelerating. car seems to choke.


go to Dollar Tree and buy a $1 Fuel injector cleaner. pour that in your gas tank and fill up with PREMIUM, 92 or 93 octane. Most times its cheap gas (regular). Premium will get you 5 more miles per gallon and alot more power.

Chry 300c 06 stalls after filling tank


Tell me when you fill up how far do you go before it stops,,then how far does it go the second time and the 3rd time ,,Do the times get longer each time,, if so then your problem isent a big deal.
The problem you might have is that the return fuel pipe from the engine returning fuel back in to the tank,, and the TANK breather pipe which has to let air in as you cannot take fuel out and not let air back in ,,so it causes a vacuum in the tank... So check the breather before any thing else .. OR dont fill it up any more than the first click of the pumps .
Let me know how you get on Ron

Check engine light on. had mistakenly filled w/87


Different octane fuel should have no real or lasting effect on your car except perhaps a bit of slight detonation. (computer will normally compensate for this by retarding timing a bit. Since you added higher octane fuel, the mix should be slightly higher than in the beginning. To improve octane of remaining fuel you could add 3oz of acetone to each 10 gallons of remaining fuel, or drive it and keep adding 93 every time you use up a quarter tank.
I think that you may not be having a problem with the fuel itself but may have an improperly sealing fuel cap. That would turn the light on.

Engine runing rough


This code is most likely not related to the problem, it sounds like you may have picked up some contaminated gasoline, maybe has water in it or other like dirt.

Engine running rough


It sounds like maybe yu have a fuel filter that getting plugged up.
To check this, see if you can remove it from the engine, then very carefully blow thru it in the direction the fuel travels, if clean you should be able to blow thru it easily, if not then replace.
The P132 is (E132) .................. Knock Sensor Circuitry Failure .... The knock sensor is what prevent engine ping from low octane. ...
It could also be you just got some bad gas.
You also might try topping off the tank with gas from another place and bring the octane level up if that is the problem.
Hope this helps
Good luck

Loud engine or Muffler


hi. if the muffler is truly cracked, it will release a loud, unfiltered, noise during acceleration and idling as well. it will rattle as well. i recommend replacing the muffler ASAP.

Concerning the fill up at 7-11, there may have been a high water content that was in this gas stations tank and, this was transferred to your tank during the filling. the Lucas treatment will remove the water out of the tank and correct any damage that may have occurred,if any..
