    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    UPDATE: Drove it home today, good to be back in the PW!! New cam, lifters, and all exhaust manifold bolts replaced, while heads were out, plus all the other misc for $5k. (only $1500, for 15hours of labor. Thought that was pretty good for LA.) And found out I am still within my 3rd party...

    Yes I will. How does one post picture here? I only see the option to point to a URL? Ahah just noticed you can upload a file....That should work.

    Thanks as always @Tach_tech ! Two more questions. 1. When you have replaced cam and lifters, with OEM parts - Have you had any clients get another 80-120k miles yet? If so, are the replacement parts holding up? (or is this an every 100k miles thing?) 2. While the heads come out for the cam /...

    Yep @Tach_tech , that is crazy high. They checked codes, checked the coil, and did compression test for $180. I asked how long the leak down would take and they said 2 hours. So I said really, so you labor rate is $190 an hour and the service advisor said yes. Guess that is why the dealer ship...

    Cam/Lifter failures in relation to oil level

    2012 Ram 2500 power wagon here with the cam/lifter issue. Tear down started today :-( -> when replacing the cam / lifters (and other parts.) Does that solve the problem, or are they going out a 2nd time? after another 80-120k miles?

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    Thanks guys. Was at the dealer for two safety recalls and got a free rental 1500, so I figured why not let them do the diagnostics. But now that they want $380 to do a leak down test (after being charged $180 to basically check codes and look things over)....I'm starting to think I should just...

    Cylinder 1 misfire, please help!

    Hi, Did you ever figure out what the problem was? I am in the same exact situation with a 2012, cylinder one misfire, while towing, and at high rpms!!

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    Thank you. What kinds of problems, with good compression would a leak down test identify? Thus far: New spark plugs, new coils Vacumn test is good Voltages at the fuel injector are good Compression test is good And this misfire code is only thrown when the engine is under load (towing) or...

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    Dealer wanted to diagnose before reprogramming.....Compression test was good. Now they want to do a leak down test. But I thought that was only good to ID where it is leaking compression, if compression tested bad? I guess the only way to test the fuel injector is to replace it or swap it with...

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    UPDATE: Oil has been synthetic mobil 5W20 Mechanic performed vacuum test and all was normal at various rpms. Checked fuel injector voltage and it was right in the middle. They then drove the truck around with the code reader/scanner connected and noticed the U1449 would come on first, then the...

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    Oil is factory recommended. Will check paperwork history when I get home to see what actually has gone in. Going down the compression test, vacuum test. Along with measuring the voltage at the injector. Diagnostics as we speak. Step 2, Based what they find. I’ll then swap injectors between...

    Cylinder #1 misfire (P0301) and CEL, but only at 4500/5000 rpm and above

    New here, and of course need some help. My searches haven't popped up with the same scenario. So I thought I'd ask the experts here: Have 2012 RAM Power Wagon with 5.7 Hemi in it, with 92k miles and have owned it since 8k miles. Late Dec. While towing, I had a blow out (going up hill) on one...

    Sorry late to the party, 436 pages late to be exact. Have 2012 power wagon and would like to adjust transmission shift points and adjust my TPMS, for the 35's I'm running. Does this work for 2012 model Year? And/or is there a better thread to for MY 2012?
