I fully agree they should have lasted longer.considering it hasn't been driven daily till lately. My plans are to change the crank sensor and do a full tune up minus the plugs since they were replaced. Finding Mopar replacement parts is a hunt in itself. This truck has ran smooth before so something is off. Fuel millage has been really good since I filled the tank Monday and have driven it back and forth to work ( Roughly round trip is 16 miles) and it has barely moved off the full mark. As you know, a lot of work has been done to the truck motor and transmission. I will say every once and a while it will take me a couple of times to start but most of the time it starts right up. I will update after this weekend. Hopefully I can chase this gremlin away. lol

 

I will be doing the tune up tomorrow but here to ask a question about fuel injection cleaner kit/tool. I have been looking into these kits that you can use to clean injectors as well as carbon build up. This is the hanging bottle type that you use with a compressor. I am also trying to stay in a budget range that fits for something I may use a few times over a course of a year. My thinking is 1) it would be nice to know the injectors are clean and working properly and 2) It say's it cleans up any carbon build up and something else I can't think of at the moment. It would make a good investment since I am sure it will save in cost paying a shop to do the same thing. Have any of you guys used or have one of these type of kits? Amazon goes from $55 to $300 very easy or even more. Also isn't there a filter on the intake side of the inject to protect it from clogging? I have seen some videos that say there is and talk about how to remove such screen but it will have to be replaced. I don't see anything when looking at injectors on screens or replacing them.. Thanks

 

Since you haven't figured out if it's a fuel or ignition issue replace the ignition parts. Still have the issue put a timing light on the coil wire/plug wire and watch for the misfire. If it drops out you know it's ignition related.

 

I agree. This is why I am going to do a wire,cap and rotor change first. I figure it's cost effective getting the injector cleaning kit since a shop will charge me around or close to what the cost of a DYI kit and I can use it to keep up good maintenance. I just dread having to hang over the motor to change them. lol. I did check the plenum and it was clean. I will have to order a decent timing light online. Haven't used one since I was a kid.

 

There's no better excuse to buy a topside creeper!!

 

I never knew about them till I searched lol. Us old folks don't bend or stretch like we use to.
