Re: P1004 code for Dodge
Concerning the P1004 code... I own a 2007 Dodge Charger 3.5L. At my shop, after checking the light, Mitchell has a TSB out for that particular code. It is requiring to replace the intake plenum AND the actuator. Whether it is one or both, I am not sure at this time. Wasn't able to print out the TSB and our printers are down... computer problems. I also noticed that on my last tank of gas, my gas mileage dropped TREMENDOUSLY. I usually average 100 mi/quarter tank of gas, and on my last quarter, i usually get 50 to 75 miles before I have to fill up. Well, I got about about 225-250 miles on my last tank of gas before I had to fill up again. My driveability technician and I both figured to try a fuel system service to see exactly what that would do. The only reason for that is after removing the actuator, we could see alot of "oil" on the intake runners; similar to the oil that you would use for K&N filters, but quite dirtier. Needless to say, we did the fuel system service with a 3-part treatment from the Wynn's fuel service company, added Lucas fuel treatment (the quarts. 32 oz bottle. 3 oz per 10 gallons of gas, quite potent!) I have roughly a 40 mile round trip every day to and from work, and my fuel economy is right back where it was previous all these problems, about 100 miles on the trip with 3/4 of a tank of gas left. If this should happen to help anyone, please let me know. Both myself and my driveability technician are VERY curious as to see what these motors are capable of.
