Truck help

After replacing the plugs and air filter and cleaning every wire, connector, and sensor… I took it for a test drive, engine doesn’t misfire when given gas in park, but as soon as it is in gear, the misfires start happening. When driving it still lacks in the middle ground acceleration. It bucks slowly when keeping pace, but when accelerating it gives too much and slips a little at the top end. I think the timing is a good call, but I have a feeling it isn’t the only thing wrong. I’m going to have someone with more experience than I take a look at the timing and make sure it is set right, with a new belt. I opened up the timing box and know enough to say it isn’t a bad idea to put a new belt on. I also noticed 2 things after the test drive. The radiator was hotter than I think it should be, even though the temp gauge showed dead center, and the cat was extremely hot; I couldn’t tell if it would have gotten hot enough to glow, but the damp floor on the passenger side was steaming. The water pump isn’t leaking, but I think the thermostat may be lodged open, so I’m going to check that out too and see if it needs to be replaced… Thanks so much for your help so far, from everyone I’ve consulted with, you have been one of the most helpful!

If you can get the cover off it is easy to check the cam timing. Put the crank at tdc (there should be a mark on the pulley or sprocket to line it up). Once the crank is at tdc check the cam sprockets, they have marks on them as well to line up to the cover behind them.

Miss fires on cyl 1,3,5. After you went through the mud. I bet you fowled the bank 1(cylinder 1side of engine) upstream (before cat converter)o2 sensor It may not set a code for o2 but if you look at fuel trim data I bet it will show. Cam timing as a cause is very unlikely. Coil spark plugs and injectors will all set single cylinder misfires but you have bank one (cylinder 1 side of engine) setting.my advise is replace b1s1 (bank 1 sensor 1 o2 sensor and re evaluate

Well it was the timing… It took a lot of work and time trying to track down tools needed, but the right cam slipped 3 teeth, just enough to cough up the 1,3,5 cylinders under load. I do have 3 new handmade tools to take a toyota 3.4 crank shaft pulley bolt off if anyone ever needs to borrow them in the future! She now runs more smoothly than she did when I got her and I also now have working AC! Thanks all of you for the time you spent in replying to this and offering suggestions and guidance, it helped me save a lot of money by not having to bring it into a shop!

Glad you figured it out, hopefully you didn’t miss too much time out in the woods.

I missed all of my fall walleye fishing, but I got a lot of grouse hunting in that I normally never made time for… I also learned a ton about my engine and just motors in general from it, so there are really no complaints. It cost me a grand total of about $250 bucks for parts the truck needed anyway. I can say without a doubt that I am glad I got stuck in the mud. At the same time, I definitely don’t want to do it again! Thanks again bud!
