    Driving home from a 80 or so mile drive the truck started to misfire at about 70mph with cruise control on. So i slowed down to 50ish and floored it to 85 and the problem didn't come back till I got like 5 minutes from home. And same thing. So I floored it again from like 30 and went to 95 or so...

    Magnaflow 12388 and dual exit pipes

    OK just finished the job! Started 4 hours ago lol. That has got to have been the quickest I've ever cut a muffler off and redid the muffler back on any car or truck... ever. I got a kit from Amazon for ~$150 it was pre-bent mandrel bent pipes to convert the single side exit to dual rear exit...

I was able to drill the top left out but I cant get to the bottom left bolt. The previous owner...

    Excessive oil consumption

    I have a 2007 1500 5.7 with just under 140k miles (139,946) and I’m losing a quart of oil every thousand miles or so for some reason. It doesn’t seem to be leaking and i cant smell oil out the tailpipe. I haven’t replaced the Pcv valve because it seems to be operating normally and the intake...

    3rd Gen 1500 owners beware!!!!

    This is the 3rd truck I've seen with an issue similar to this. Slight vibration when turning at higher speeds, vibration when driving fast, and a clap in the rear. I went under my truck yesterday. I jacked it up in my backyard, put 2 jact stands under the rear axle and put in in drive to ab 55...

    Truck vibrates over 50 mph

    Hi my 07 1500 is vibrating over 50mph. It goes away when you accelerate but as soon as you lift your foot it comes back... sort of feels like a high wattage sound system or those lane warning bumps you go over if you leave your lane. It’s really annoying and everything rattles. Started after i...

    2007 1500 QC no floor heat

    2007 ram 1500 no heat on the floor setting. Defrost, front vents, etc all work fine but no matter what I try no air comes out of the floor vents on driver and passenger side. There is a very very minimal amount of airflow at max speed. Any ideas? Sent from my SM-N975U1 using Tapatalk

    Click in steering wheel

    I have an 07 1500 that has a click in the steering wheel. This gives it a little play. It's not in the rack. Feels like it's in or if not very close to the steering wheel itself. It started when I was on a long road trip and hasn't gotten worse but there is a notchiness to it almost like one...

    Torque Converter lockup making a howling sound when locked up

    In 4th gear at ~40mph my transmission makes a howling sound I believe is the torque converter clutch locking up. Itll do it in OD OFF and TOW/HAUL and normal whenever the TCC is locked up. The sound goes up and down with rpm and goes away above 2k rpms. Does this mean my tranny is going or I'd...

    5.7 1500 supercharger noise at 40mph

    My 07 1500 5.7 545rfe makes a whining, supercharger-sounding noise when the truck shifts into 4th gear at about 1300-1900 rpms. Pitch increases as rpm increases but goes away at around 2000 rpms. It does it a little bit in 3ed gear if rpms are low enough... very strange. Comes from passenger...

    Adding a dual exhaust on an 07 1500 hemi

    I've posted a few threads on this already, but now I'm getting serious about this... I'm ready to buy. So the single exhaust on the 5.7 has a muffler and then a resonator about a foot or 2 away from the tailpipe. My question is, because I dont want much drone, and I have the Magnaflow 12388...

    MagnaFlow exhaust

    I’m thinking of buying the MagnaFlow #12266 muffler single in dual out on my 07 1500 5.7. Does anyone know if that pipe after the cats where the 2 pipes merge into one through that crimped connection reduces performance? It’s like 2 2.5” pipes into one 2.5” pipe under the passenger door.

    Idle jumps around like crazy

    So I'm at a stop light this morning waiting to turn left and all the sudden my 2007 1500 5.7's idle just starts jumping around like it ready to stall. So I give it gas and it helped a little and then started doing it again. So I put in in park and I think that sorta fixed it. When the light...

    Transmission makes grinding sound when shifting

    My 2007 1500 5.7 with the 545RFE tranny is doing something weird... when under WOT, when the transmission shifts at around 5500-5800 rpm the truck makes a very quick grinding sound. Not sure if it's the VVT, transfer case, or tranny. Anyone with the same problem or a solution to what it cound...

    HEMI Tick - Only A Matter of Time

    I bought my 2007 1500 Hemi with 130k miles. Orig. head studs/bolts. Figured it was only a matter of time before I’d get the all-to-common tick... well, as of yesterday, it showed up. I only see one bolt/stud left on the whole left bank. Does anyone know if i can just rethread or restud the heads...

    Marvel Mystery Oil in HEMI

    Thinking about using MMO in my 2007 1500 5.7 with 135k miles. Anyone try this before? Do you put it in while filling oil after an oil change, 500 miles before or 5 minutes before? Never used the stuff before. My dad swears by it in older cars, but with VVT and especially MDS I’m not sure if that...

    Best Exhaust System/Muffler for 07 1500 hemi

    I’m looking for a muffler or exhaust system that will keep the cabin close to as quiet as the stock system, but louder outside. I like the nice rumble at idle and a good sound when accelerating, which you dont get with the stock system. Heck, you hear the engine over the exhaust sound! But i...

    Bed lights wiring for 3rd gen

    I'm trying to install bed lights on a 2007 1500 5.7 hemi. Not sure if I should give it it's own fuse, run it off of another fuse, or solder the wires directly on the always-hot power outlet in the interior Sent from my SM-N975U1 using Tapatalk

    Idle goes down to 500 when stopped in Drive

    My 2007 Ram 1500 5.7 Hemi-when warm- at a stop light will decrease in rpm to about 500 or a little lower almost as though it is being strained by the tranny because when I put it in neutral it climbs right back up and when put back in drive it stays up. Only after I accelerate does it happen...
