Just changed plugs on my Ram 1500 hemi, valve number one had burned plugs. After doing that the engine is getting hot at high RPM. Could the problem be the fuel injector in that # valve ?
You are probably referring to "cylinder" number 1. Take a photo of the burned spark plugs and post here.
Ok, here
The mechanic wants to change fuel injector on that cylinder. Do you think that’s the problem ?
Why are you thinking the plugs are burnt? The electrode, insulator and ground straps look pretty normal. How many miles on this engine? Is a check engine light illuminated? How high is the coolant temperature getting at high rpm?
Not sure how hot it gets, just what the mechanic said. I couldn’t tell if those new plugs were bad or not, jus had them changed back in November. He just said it was getting hot at high RPM and it could be fuel injector on that cylinder. Or the OEM, whatever that is. Does that sound about right ???
I am not sure what he is telling you is good information or not. If it is running okay, not getting hot, and there are no check engine light(s) illuminated and fuel mileage is normal I wouldn't think it has a problem. You are obviously not a motor head so something may be getting lost in the translation (no offense intended).
I’m not sure either, I’m no Motörhead. No offense taken. Just relaying the info I got. Thanks. Check engine light was on, and machine said #1 cylinder not hitting. That’s why he changed plugs. But those plugs were put in back in November. He just said after he did that that it was hot at hi RPM’s. Said it may be fuel injector or the OEM, or something like that. Have no idea what he was talking about. He’s not my regular mechanic, but is trustworthy. Just hope we fix the right problems.
I think Bob is right. The plugs look used but not burned. Is there is no trouble code for cylinder #1 I would not worry. Is the check engine light on now?
If there is a trouble code for a miss on number 1 and replacing the sparkplugs and the coil did not fix it then either the fuel injector or associated wiring is at fault or you have a mechanical issue with the valve train. Valve train issues are common on the 5.7 engines and the problems include bad camshaft, bad hydraulic lifters, broken valve springs and broken rocker arms. Sounds like your mechanic may be on the right track. You last post helped.
