It cost me, which is an ignition coil spark plug wire, can render a truck or even a motor home undrivable and also i'll. Tell you exactly what happened to us here at tfl truck with our project vehicle, our f250 2020 truck with a 7.3 liter godzilla v8, and also some reports that i've heard from other owners. Guys, like you and gals like you who are on the road and actually having an issue with their truck, so let me explain to you how the issue occurred on this particular truck our f 250 super tremor. I was actually camping with the truck for a video. We were filming and i was just driving out of the camp spot and um. I went down to get the boat, we had the boat in the lake and i was pulling up on the boat ramp going about. Maybe one mile an hour really crawling slowly and i felt a little bit of a vibration and i noticed a engine light blinking. Well, okay, i got a little bit worried, but i pulled the boat. The rest of the way out and i'll show you i'll start the truck in a second and i'll. Show you exactly what's going on now now, right now the truck is fully fixed. This is the solution um. Then i drove a little bit ways home. I was really concerned. I was really worried, but the family was in the truck and uh. We got the boat home um.
I took some side roads. I was going slowly not on the highway. Got it called the dealer, and first thing that happened to me was uh. They couldn't see me for about nine or ten days. Yeah there. All the dealerships were backed up. I called about five dealers uh the next morning. None of them could see me right away. Uh the best i could do was four days, but they didn't know much about 7.3 liter trucks. Plus i have a camper on this truck so finally found a dealership local in colorado. They said come back in nine days, so we're filming a series of videos with this truck no pavement needed. As you know, it was quite stressful, but then i started looking into it further. I this is obviously a modified truck. It'S got a giant, lift kit suspension big tires 37s we've been beating on this truck for about 10 000 miles right here. You can see. Currently we have 10 846 miles on this truck and this problem occurred. What about i want to say 400 miles ago, so at least 10 000 miles were problem free. It was beautiful. I even did the oil change uh video for you guys before 10 000 miles uh, where we actually changed the oil in this engine uh. We did an analysis on that oil results came back, you know with no issue. Everything was great. So finally, i read the code. Um got a scanner on the track.
Read the code. The code showed misfire on cylinder 2., so misfire can mean many things. It could mean an ignition problem could mean an injection problem. In this case it turned out to be this wire and this particular part number. You could see right here lc3z12286, so we also had a tune in this truck, so we weren't exactly sure what caused the issue i'm just being totally open and honest with you guys so finally got the truck back to the dealer. The dealer confirmed it is a misfire and cylinder number two in this case. One cylinder was misfiring and i could actually hear it when the truck was actually idling. You could kind of hear this misfire happening. Then um. I learned from another dealer uh that they have at least two other trucks with the same problem, but these were uh brand new trucks actually um, and i i didn't i wasn't able to get all the information about it, but these trucks were almost zero miles on Them also had wiring harness for the coil ignition system, and i don't know what can go wrong with a wire like this it's. A very simple wire it's got a spark plug and i'll. Show you, under the hood in a second and it's, got a little coil connector on this side. I don't want to open this, because this part is, very, you know precious um. I have a couple of stairs uh. I was able to buy a few of them, as you can see here and they cost 24.
38. I was finally able to find a dealership in florida that had these parts, then i got an email from ed, a tfl truck uh viewer. He had an issue and it turned out to be the same problem so now: i'm thinking wow, so it's, not just us it's, not just this. You know custom project truck that we're working on it's. Actually, people having this issue with the 73 point, uh v8 engine and we've heard at least three other vehicles that this has happened to recently ed has a different problem. He has a motor home with a 73 godzilla engine once again, um brand new engine brand new motorhome. He was on the road and he uses his motor home all the time, as he told me, and he went to a dealership. First of all, he was having trouble once again getting his rv to the dealer. Finally, got it there, they found three misfiring cylinders, not just one but three and he's waiting for parts he's been waiting for 30 days and the motor home is basically his mode of life it's. Not just you know that he has a motorhome parked next to his house, yeah. So a couple of different problems here, um i reached out to ford we're still waiting for comment uh from ford any official comment, but there is really kind of three things going on here: um. Yes, a very simple part can make your truck basically undrivable, because if you have a misfire, they don't recommend driving the truck um.
I got the truck home. I was able to do it short distance, but you could have you know too much fuel in the cylinder. You can have a burned out rings, you could you know overheat, the engine. You can crack the block. A lot of bad things can happen if you have a misfire, um, so part shortage. I understand it's 2020 covet. All of us are struggling very in a bad way, there's a part shortage. Then there is a part problem. Something is happening with a lot of these wires. I looked as recently as a couple days ago. There was no open recall on these trucks, so i think this. This is not quite open yet and then finally there's a service issue. Yes it's once again, 2020 virus is happening. The pandemic is happening. A lot of people are trying to maybe get their trucks fixed. Cars fixed so it's hard to get it diagnosed and finally, you know it's hard to get to the core of this problem. Ed told me that he wrote emails to the executive office at ford. He called them. He called the rv dealership. He called the ford dealership and nobody's giving him a straight answer. Why three wires um? Have you have to wait 30 days or more to get your truck on the road? So let me start the truck and you can see it's running nice. Let me move this down to neutral. Look nothing here.
This is where a check engine light would be i'm. All clear, nice we've actually been filming with this truck again took it off. Roading beat on it with this new wire drove it about 500 miles, uh went off roading in hot conditions. Dusty conditions really beat beat this truck up hard for no payment needed no issue um, since the fix was done. It took me about two weeks. I called about 12 dealers to find this part in florida. Like i told you, let me show you under the hood really quick before i close this down, and i have to give huge thanks to our ford dealer, brighton, ford, colorado and also to ford, because this issue was taken care of under warranty and in the end We got the truck back on the road, so it's a little bit of a challenge to see this, but if you can kind of lean in this truck is now like nine feet tall, so i have to climb on top of it. So, as you can see here, uh every cylinder has its own ignition coil. Basically, and these wires are actually identical, you might think they might be different lengths. Something might be different here, but basically this part is this wire that connects the coil to the spark plug and it basically tells the cylinder when to fire. Obviously, four on this side, four on that side, cylinder number two is actually um on the passenger side of the vehicle, that's also kind of difficult to find out exactly which cylinder is which you can find out.
If you read the owner's manual, you can find out the firing order, but sometimes it's difficult to find exactly which number a cylinder is which, but once you get the wire i mean it's really and if you know exactly what the problem is, because you would have To test the coil test, the spark plug test, the injection system, i wouldn't recommend you just swapping wires and driving cross country. You really have to find out exactly what was wrong, but once you do and if you call around and if you can find a dealer with this part, then finally, you can get this truck back on the road. So this is just kind of a real life experience that we've had with our truck, and we heard problems that other people have had. So let us know if you have a similar problem, how you resolved it or if anything else has happened on your vehicle and go back to tfotruck.com for all the latest news views and real world truck reviews.
