im back previously i was trying to get opinions on a tranny problem and had to break down and get it replaced. She drove good for about a month then one day on the highway the car started shaking like it was having a major miss-fire issue. when i came to a stop it idled very hard almost to a stalling out point my rpm's hovered at or below 1000. no matter how much pedal i gave it nothing but shaking so i limped into a gas station turned off the motor looked for anything unplugged leaking smoking ect and nothing. got back in started her up and it felt fine as soon as i put in in drive it started to shake again i proceeded home and like a light switch it stopped. currently i am using the oem champion copper plugs i was using autolite platinums before that. but when i put them in the car was fine it started maybe two weeks after. so i second guessed my self and thought maybe i did not gap a plug or two correctly i went thru all 16 again and for te most part they were all on point i adjusted a few but they weren't far off. i will add that i did notice i white powder like film on the fire point of the plugs and this was after two weeks of use. so i re-conected my bettery took the car for a spin and she was purring so its been about a month now and today it started again. any tips to narrow down the root cause before i damage something further? i will add i have not changed the the plugs yet since i've owned the vehicle or the coil boots can this be the possible issue? i do regularly service the oil with mobile 1 syn and also the plugs,the first round it had champ i changed them with autolite plat to help with the stallouts found in the 04 5.7l hemi and those were replaced with champ oem copper plugs which are in there now right now im a 145k. when it acts up i cannot accelerate at all right now the car idles hard but when i push the pedal it feels as if it miss-fires for a second and the power kicks in. is this a miss-fire or possible electronic issue because when i checked the plugs i did unplug my battery completely?

 

I run iridium without problems, but do get a P0300 code every once in a while as my Durango needs to be put on a dyno to tune. My transmission went out and it would lag from a dead stop and then accelerate normally. Your Hemi has coil packs, not boots.

 

i went and had my codes read today because apparently reseting the computer will stop the issue so it seems to be electronic. the code that i was givin to me was p0132 wich is a 02 sensore connection damage? where are the locations of the sensors on the 04 5.7l?

 

The 5.7L engine (348 CID) eight-cylinder engine is a 90° V-Type lightweight, deep skirt cast iron block, aluminum heads, single cam, overhead valve engine with hydraulic roller tappets. The heads incorporate splayed valves with a hemispherical style combustion chamber and dual spark plugs. The cylinders are numbered from front to rear; 1, 3, 5, 7 on the left bank and 2, 4, 6, 8 on the right bank. The firing order is 1-8-4-3-6-5-7-2.

Here is how most dealers look up the codes. Since you have code P0132 that is 1/1, I'll break it down for you. 1 meaning the odd fire side of the engine and the second number will be the upstream sensor. If you have a 1/2 code, then it would be the odd side bank and the downstream sensor. I hope this helps.
