2003 F150 Transmission issues.

[N80]

You are exactly right. One of the traditionally easiest jobs is now one of the more difficult ones. I'm a fairly proficient shade tree mechanic. I do all the brake work on my track car, I've changed shocks, I've changed carbs and headers on much older vehicles, done water pumps, valve adjustments and that sort of thing, again, on older trucks. With modern vehicles it is not so much the difficultly of the actual part or problem, it is getting access to that part or problem. Plus, I'm now living in the old family home on a (quiet) downtown (small) city street and I have no garage. So any project I do is in the driveway in the elements which also makes things that much harder and something I have to consider even when I have the tools and skills to do a job.

True that ^.

Update. Problem is still there. Not as bad and still not CEL/code. I checked and the mechanic did replace the right coil and plug (whole job, parts and labor $115 which I thought was reasonable). So, possible options include: 1) The misfire is not due to the coil or plug. Could be injector related but seems doubtful. Would expect some other code for that possibly. 2) There is another misfire on another cylinder. I will not know until it throws another code.......while I have the OBD reader in because that #$%^ light goes off and on even when there is a "severe misfire" according to the code. 3) It isn't misfire and maybe it IS the transmission still. Seriously doubt this is the case. As the #2 cylinder misfire was getting worse and the CEL finally came on it was the exact same symptoms just more and worse.

I think I am going with diagnosis 2. It is common when one coil/plug is going bad for the others to follow. Mechanic has quoted me $225 to replace remaining 7 spark plugs. I can get a whole set of coils for $150 so I'm looking at $400 to get the whole job done. It might not solve the problem but it is time to do the plugs anyway.

The truck I want to buy is a 2012 Nissan Titan Pro-X4. They're running close to $30k used with around 30k miles on them.:shocked::shocked::shocked:

So if replacing all plugs and coils works, I'll keep driving this truck. If not, time to get a loan and buy a used truck.

I would agree with your diagnosis of #2 and I would do exactly what you ask. When mine first went out, another followed shortly after. $400 is less than sales tax on a nused truck. Good luck!

That sounds like a good price, to get the rest changed out.

With just a bit of luck, that'll be all it takes.

Where are they assembling the Nissan trucks do you happen to know I couldn't find anything about it. I wonder what the US parts content is on those.

 

[N80]

Canton, Mississippi.

Great thanks I was hoping they were assembling them here. I'll keep checking see if I can find parts content. I know Toyota was boasting 70% US content hopefully Nissan is close to that. It's always nice try to keep things as made in USA is possible.

Finally found it looks pretty good they rate just below ram 1500 and just above Chevy and GMC 1500. With somewhere right around 50% domestic content but they rate pretty well as far as keeping profits and research and development here as well. It's cool that they are using a Cummings turbodiesel option now.
