Thanks to all who post here. The many tips & techniques shared in this forum have provided much needed insight and understanding. I've finally got my Hemi, an 05 RWD 300c, thanks to a deer which totaled my '13 300 (Pentastar) AWD.
This is a thread sharing what occurred: Thought I’d found a jewel. Idled smooth, ran strong (local test drive)…155k, but impeccably maintains, egr valve, regular oil & tranny service, from battery to CV... receipts!
Now skip ahead to the ride home: pulled onto the highway strong… settling into the car a bit… went to pass someone, and it lost power… sputtering, shaking… was grateful it made it home.
During most of the torment, there were no codes. The MIL would flash because of the misfiring, but no code. Though P1416 code finally came up after more than a week…
#6 was misfiring, and so we changed the coil and plugs. It seemed fine… till the MDS engaged, and it was the same shake rattle and roll it back to the garage. So replaced all the coils, plugs & wires… repeat the same scenario.
Fast forward to the finally: three of the new solenoids had gone bad. One solenoid would consistently engage but not resume. The other two were shorted.
The caveat here is that there was a receipt for all four MDS solenoids being replaced at the stealership less than a thousand mile ago (4 months). The solenoids we pulled were pristine, the previous owner didn’t get screwed.
This may or may not be a factor: during the ‘check wiring’ part of the trouble shoot we had trouble starting the car. We found the harness running to the tranny had been cooked by the exhaust. While poking around, we’d allowed the frail wires to short. After repairing the wiring, the car started and we pulled the intake to find the faulty solenoid(s). #6 would activate but not resume, and two others were shorted… replaced all (again).
Blondey is to be my daily driver for some time to come. Given the hundreds of miles logged each week commuting, and gas bouncing off $4 per gal... eliminating MDS wasn't an option.
