I'm coming here 5 years after you posted this. I don't know where you are now bro but you saved my bacon! I had shops throwing electronic parts at this thing even telling me my cats were clogged. I saw this video, took apart the front end of my engine, and found that crank sprocket had an entire belt tooth worth of wear in the keyway. My valve and ignition timing was probably going back and forth 10° or more. This is a mechanical problem that seems like an electrical problem to everyone who looks at it. Those shops were just going to keep taking my money and they would have never found this. Thanks a million for posting this I'd send you 50 bucks right now if I had your PayPal.

This is the type of crap you find on a motor teardown, very VERY difficult to find in your situation (not tearing down). Really good stuff man, definition of not giving up. I've always felt when a job goes perfectly you learn nothing, this 3.4 sent you to school and you came out with a well deserved degree. ALSO I've got a 98 Tacoma with 345k and no idea when timing belt was changed last AND she seems to be lacking in the power department, will definitely be checking this when doin that job, something I had ZERO idea I should look at while I'm in there. Thanks big time for that, think I'll be checkin out more of your skills. I work on shit, I know how hard issues like that can be. This video is just awesome... and greatly appreciated.

Absolutely!!! Computerization of automobiles is great, but no matter how "smart" the system is, it's always going to miss something that it wasn't programmed to observe. This is where you put the scan tool down and use your hands. My usual practice, when I buy a used vehicle from a seller who didn't keep good records, is to replace key components, fluids, and update records from that point forward. Peace of mind is better than being broken down away from home. Keep me posted on what you find.

There are so many different reasons for sluggish throttle or hesitation; man you cost this customer a lot of money in diagnostics. I had sluggish throttle and hesitation, and when spark plugs, new coils, and plug wires didn't work, I replaced the MAF sensor with an aftermarket one and the problem was fixed. Cost me $37 for an aftermarket one on Amazon, so I bought a second one in case that one failed.

Sounds like throttle body nonsense is caused by timing confusion: need a screen to log crank timing signals vs. cam timing - this instability would show up, as the drive hub on the crank walks around it's [trashed] keyway. Is there a handheld that can do that? I have an OBD tool, but don't think it can catch data with millisecond accuracy [plus the screen is too small].

That's exactly what happened, and lead me in the wrong direction originally.

Well im thinking this might be the issue with my 4 runner, it loses power badly up hill and when i get to the top of the hill its got full power. Iv done spark plugs and the fuel filter and ran some 44k fuel cleaner through it and its not helping one bit. Its starting to get really annoying lol.

besides being worn out, why does the gear/cog in the crank move. It would have been nice to see what was locking it in place after you pulled it out a bit and turned it. Great job diagnosing it. That thing will cause all sorts of problems and readings

Travis k thanks. I'm almost done editing the "fix" video, and you'll see that the keyway that held the cog in place at the worn spot.

Still hoping to see that "fix video." Would love to see the follow-up to your investigation as I think I've got the same issue with my 98 Tacoma. Thanks!

I think one reason for the cog keyway and woodruff key becoming worn is the crankshaft pulley bolt not being torqued to spec. and it works loose. The spec is 217 ft/lbs for the first generation 3.4 v6 tacoma pulley bolt, I used a new bolt from Toyota that has thread locking compound pre-applied, if I were to re-use the old bolt I would use blue loc-tite on it, but it's a $10 part so I use a new one.

Thanks for the video! Thankfully, my sprocket didn't have this wear, but thanks to you I was watching carefully when doing my own timing belt replacement. That wear looks quite unusual though. How many miles did the truck have on it? Manual or automatic?

Wish I'd seen this 4 months ago.. literally just replaced crank gear engine idled rough had poor power and threw misfire codes on cylinder 3 and 6 everything I climbed a grade. .the gear looked perfect but when you placed the relucter on a flat surface it had 2 bent teeth and a bit of a warp to it.. if that relucter wheel isn't perfect it will cause the engine to run horribly and you will be chasing ghosts

I really hope this is the problem with my truck. I've been running circles in circles trying to figure out what is wrong; changed all my ignition, injectors, fuel pump etc... didn't even think of this when I changed my timing belt. Hopefully this helps me!!

This is helpful! What did you do to correct the bottom -- crank spline? How'd you get that spindle to ride where it needs to? I have the same engine, 3.4L V6 on my '97 Tacoma 4x4... just turned 290K and got my first ever 'check engine' on the dash. The symptoms were, it started strong as always, it idled ok, there was no hesitation in acceleration but when I got to speed and the load fell away the RPM fell off as if I pulled my foot off the pedal. I wasn't able to get a reading on it. Five different devices couldn't read it. Toyota couldn't read it. The truck had a stroke, I've got the brain out getting refurbed and I'll get it back in like five days. I have been racking my head trying to figure out what might have caused the power glitch -- because the check engine light came on at the precise moment that the power fell off with no load. You showed how that can happen. Now all I got to know is what did you do to fix it, did you video the job? Thanks, KCOD
