Runs rough

Glad to be here as a new person. Used to own a 1977 Toyota Corolla station wagon with 2TKC motor. Awesome and simple 30mpg. Now my 2001 Toyota Tundra v-6 is a pretty good motor but...1 day getting off the hwy and stopping at the traffic light there was a noise not loud, but by the time I got home the noise was pretty loud. So I lift the hood and puffs of white smoke was coming from the #1 cylinder area in front. I don't know why I didn't check the simple things 1st but just assumed it was a blown head gasket. So the next day I start tearing it Apart and by the time I get down to taking the head off I take the spark plugs out and to my Surprise there was a spark plug in the number one cylinder Where the electrode had broken off. So that cylinder wasn't firing it was just a spark plug boy I was pissed. So I went ahead and did the gasket job Now I can't get it to run right. It's running a lot better now than when I 1st put it back together I was getting backfires all from the 135 cylinders So I took it apart again and one of the Gears on the exhaust Cam was off a tooth And I checked for Clarence on the lifters they were all within specs So I figured it was a vacuum problem I bought a hangs manual for this truck But it doesn't really show you a good picture of the vacuum lines on this motor And the diagram under the hood of the vehicle just shows a small part of the vacuum so I'm just guessing where all these tubes go Some of the lines before I took it apart we're not hooked up so I've been going back-and-forth put them on taking them off I really need like a picture of how the vacuum lines are supposed to go on this motor. I even watched a video on YouTube this one guy had all of the vacuum lines taken off of the intake shroud Where it just sucked in afrom one spot and the vacuum lines that went to that shroud he blocked them off . Is there any way I can get a decent picture of the vacuum system on This 2001 Toyota tundra

 

Heh, you didn't happen to buy those spark plugs on Amazon, did you? Seems to be a lot of counterfeits on there, you wouldn't be the 1st to get burned, if so.

You mention the cam timing was off a tooth. I don't know if the pre-VVTi V6 is the same as the V8, but we just had another guy who tore his motor apart and threw tons of parts at it over the course of two dozen pages, and finally, at the end, he realized he failed to install the service bolt in the scissor gear while doing the top-end work, and the cam timing was not right with the regular timing. The thread is over here, and the solve is on the last page or two: https://www.tundras.com/threads/multiple-misfires-after-rebuild-fixed.110071/

There is a decent picture of the vacuum system for the 2001 Tundra online, it's on a Russian or other Asian site, if I recall. But I don't have a link - someone else usually posts that stuff. @BubbaW or @Tundra2 maybe? I don't have time to dig at the moment.

Are you throwing any codes at all?

 

Yeah I use the service bolt but on the passenger side won three and five cylinder we're all backfiring on the codes I forgot the number of the code but I took the valve cover off and sure enough it was the exhaust cam that wasn't right it's hard to see them darn marks back there in the back I have to use a mirror with a light and I finally got it lined up right. So I think it might be these darn coil packs I bought from Amazon I'm hoping tomorrow I'm going to start it up and disconnect one at a time and see if that makes a difference and the spark plugs that I have in there are Auto lights and I don't know if they're any good I'm going to go ahead and get wires and new spark plugs and see what that does

 

So the tip of the plug was rattling around IN the cylinder?

should be able to find a vacuum diagram here:

@shifty` i dont think the 5vz is an interference engine.

 

Someone else on here bitched about getting counterfeit coilpacks on the scAmazon also. Spark plugs are way more common. But scAmazon has sent me more counterfeit appliance and small engine parts than I can shake a stick at, so I just don't shop for parts on there anymore. Sometimes it's obvious they're fakes (white boxes, unbranded bags, etc.) and other times, the packaging is very convincing.

IIRC from a recent thread, as long as your Autolites are two-electrode, you should be fine. If they're not, and are single-electrode, you'll end up with misfires.

From a recent thread with an '02 w/V6, Toyota calls for these Denso plugs to be used, but these NGKs are a known-good choice too, two electrode:

Thats right, i forgot about the double electrode plugs. And how much of a bitch it was to change em.
