Try adding a K&N air intake I have gotten 3 more mpg. It has been on my 2004 dodge for 6 months now.

I was cruising down the interstate in my 04 Ram 1500 Hemi with the cruise control set on 75 mph and all of a sudden the engine dies. The check engine light and the ETC light came on and I coasted off onto the shoulder. I put the transmission in park and turned the key to start it and it wouldn't even crank. I turned the key off and tried again... Nothing! So I got out and disconnected and then re-connected the battery. It then started up. The ETC light went off but the check engine light stayed on. I got home and parked it. The next day when I started it up both lights were off and it seemed to be running normally. When I got out on the road I noticed a big difference in how responsive the engine was when I stepped on the gas. It was much more responsive than it had previously been and reminded me of how responsive it was when it was new. I don't know what changed... but I like it. Also my fuel mileage has gone up 2-3 mpg since that happened. Have not had any problems since and whatever happened remains a mystery.

I had the same problems that others seem to have had. I have a 2004 SLT, black, the whole ball of wax. In any case, I was doing 75 from Houston to Austin, all of a sudden the cruise shut down, truck went into 3rd, all the lights came on, all we could do was 30mph. We pulled over, read the manual after I noticed the e-throttle light was on. Shut the engine off, fired it back up, no problems all the way home. Took the truck into Dodge, they diagnosed a fuel system clean was due, the explanation was the computer sensed an airflow problem and pulled the engine back to avoid a too lean condition. Once the maintenance was done, I had no problems since. That was 10k ago.

Does anyone know if you have to re tune a 2004 Dodge Ram 1500 SLT 5.7 liter Hemi after you install a K&N air intake?

Thanks.
