Hello my name is logan. I just got a dodge ram 1500 2004. It has 120,000 miles on it. I’m a new ram owner. But I have a pretty good set of mechanic skills there’s probably not a lot I could do if I was shown or you know etc. But here’s my problem and I am sick of putting money into it if it’s the cam lobe failure orWeek valve springs I think I’ve read about or the valve seats dropping. Anyways here goes. The truck ask like it’s got a misfire. It’s not necessarily when it’s idling but more so when it’s under a load. usually when you’re taking off from a stop. it gets Worse when you’re going about 50 miles an hour, and just about to shift into overdrive. So as i’m accelerating the truck is shifting gears. each time the RPMs are around when it shifts is when it starts to happen it’ll sputter kind of shake like it’s got a bad misfire and I hear a ping that sounds like a bumper on a pinball machine. And that pinball bumper noise I hear goes in sequence with the sputtering/shaking misfiring. only thing I can imagine that’s making the sounds I’m hearing is to do with the valve train. maybe like a valve spring going bad or I’ve also heard valve seats drop in these motors. And everything I know is just what I’ve read online. An experienced hands-on with working on the vehicle itself. I replace the O2 sensors I found one bad injector and replaced. I cleaned the rest of the injectors. I didn’t know how to test the coil packs. but I switched them around. I change the plugs and wires. I also change the intake manifold gasket. Cleaned the throttlebody, airflow sensor, etc. I had put it back together it ran better but still the same symptoms that to me sounds like valve springs going bad or something of that nature. please help me because this is ******* getting expensive. lol it’s only has 120,000 miles on it to I don’t know if I mentioned that. It’s a 04 ram 1500 slt 5.7 4x4 crewcab.
