One Reason why the Toyota 3.4 liter Engine is Sluggish on Throttle part 1

[@GRAZINGARIZONA]

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.

[@MeccaEl]

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.

[@LPMutagen]

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.

[@southwestxnorthwest]

This guy didn't even know if it was a 3.4 or 3.6 liter engine. Kind of hard to miss that, when it said 3400 on the timing belt cover. 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.

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

Hey man just came across this video as I’m about to do the timing belt kit on my 5vzfe. What’s the fix for this problem if I run into it? Can you just pull that front gear out (like you did) and it will stay in place or do you need a new crankshaft timing pulley and timing belt guide?

[@airsoftdude36]

Or do you need a whole new crankshaft?

[@richardcastillo5263]

Can you let me know what is the cost of the new throttle body and where can I find it ? Thanks so much.

[@MeccaEl]

I can't recall what vendor I went with, but there are some on Amazon, for about $60 on up.

[@flinch622]

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].

[@MeccaEl]

That's exactly what happened, and lead me in the wrong direction originally. That +/-5 degree walk, had the ecu offering enough self correction, for me not to see anything wrong with the crank sensor signaling. As soon as I took the upper timing cover off, and hand cranked the engine, boom, delay in timing belt movement.

[@strawboss5955]

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.

[@tomhernandez1308]

Just let you know I have a 2000 Toyota Tacoma SR5 V6 same engine but I already had the timing done a year ago never had a timing issue. I just did a tuneup on the truck but before that it had a bogging out issue so I replace spark plugs anyways cause they were shot. Put new wires. It idles a lot smoother but then when I hit the gas it’s like it’s starting to choke and I want to die out but if I keep revving the throttle, I’ll pick up rpm, but still the same shit if there’s a way you have any idea what a map sensor cause this issue or throttlebody.

Must Be A Different T.Body Than the Reg.Tundras,W/ Same Eng.Had an 01 Tundra That I Put 888,850 mls.on It & Never Had A Throttle Body Issue W/ It.When Coil Packs Were Worn Out,Never Got A Check Eng.Lite,Just Loss of Power,So I Just Chgd.Coil Pks.Every Other Time I Chgd.Plugs.I'd Check For MAF AirSensor Code,Use the O'Reilly's Blue Code Scanner,Believe It's the BOSCH One,Gives More Accurate Scans than the Cheap Orange Ones Auto Zone Uses.
