Edit: I’ve narrowed it down a little, it only happens between 1st-2nd gear shift (roughly 1500 rpm) when coming out of a stop. If I put the auto shifter into L (1st gear) it will not do the hesitation. Kind of leaning toward this being something with my ECU or throttle body/throttle position sensor or the wiring for them. It’s pretty consistent and repeatable. Thinking about taking it to the dealer for diagnostic but I know that can be questionable.

This has been plaguing me for a while. When I do a rolling stop/stop very shortly and accelerate i get a slight hesitation. It revs for a split second then it seems like it dies a little then picks right back up. If I do a full stop and wait a second it won’t do it. Ive done quite a bit of maintenance on this thing so I have a decent head start on narrowing this down hopefully.. i try to stick with oem toyota parts where I can.

Any suggestions/recommendations would be helpful!

2000 limited 5vzfe 184k miles no CEL and drives 100% fine except for this issue.

Here’s the relevant things I’ve done so far:
Replaced:
-plugs/wires
-fuel filter
-air filter
-timing belt (eBay kit Tim recommended)
-valve cover gaskets/pcv
-automatic transmission solenoids (all 3)
-throttle position sensor (got a CEL to replace this)

Cleaned/rebuilt/tested:
-cleaned/rebuilt injectors (eBay kit)
-cleaned/swapped/tested MAF
-cleaned/tested IAC
-cleaned throttle body/intake manifold
-coil packs tested per FSM
-cleaned electrical connections on TB/MAF/TPS
-over drive/ect have no effect on this problem

How far does the RPM drop? A friend of mine had something similar and it turned out to be low tranny fluid. Turn out a line busted and from a stop the damn thing could barely get up on the rhino ramps it was so low

MAF's can be bad even when they are within spec.

Good to know, might get one just to rule it out..

I don’t think it’s that. It’s been happening for a while and it drives 100% completely fine other than this. I’ll take a peek at the fluid level though just to rule it out.

I’ll try to get a little video of it happening tomorrow..

Have you tried cleaning your IAC?

Oh yes I did try that and I tested it as well, thank you Ill add that to the list.

You don't mention the IAC...oh wait, you did. Nevermind that then.

You've been around for awhile, so likely know about the very hard to see wires on the maf sensor, but since I've seen many a post that turned out they were only cleaning the bulb and not the tiny delicate wires I'll throw that in the mix.

I did clean the small wire inside too, I basically used a whole can of MAF cleaner lol. However the first time I cleaned it I noticed a decent amount of caked on dirt over the “bulb” part of the MAF and I cleaned it off with a q tip as it wouldn’t come off with the MAF cleaner. I didn’t touch the small wires inside though. Not sure if I ruined the MAF when I did that or not as I know your not supposed to touch it..?

I've had the same issue since I bought mine 5 years ago.

If I come to an abrupt stop and then immediately give it gas it stumbles for a moment and then catches.

Don't have a solution, just thought I'd share!

Have any of you with the problem ever watched your LTFT when it happens?

How old are your O2 sensors?

Haven’t watched LTFT but my 02 sensors are practically brand new. Going to try my transmission solenoids and maybe the transgo kit.

Seems like there are two shift solenoids and one over drive solenoid, found the number for the shift solenoids (180$ each.. ouch) but can’t find the number for the overdrive solenoid.. thinking about doing the transgo kit, I think there are two kits for our transmission (sk340 vs 340hd2) seems like the sk340 might be less race car like but everyone that I’ve seen do the install used the 340hd2.. hmm.

There's a write up on the 340hd2 kit: Transgo 340-hd2 install and reveiw The 340hd2 kit has 2 ways you can modify the valve body. Either truck or race shifts with truck being softer than race shifts. You might try asking the OP what he thinks of it since it's been a few years on his install.

Saw that one, there is a pretty detailed write up on Tacoma world as well. I just wish someone had a review of the sk340. I might call transgo and just see what they say about it/recommend. Probably try to message OP as well just to see what he says.

Brand new oem toyota with less than 500 miles on it.

How old is your TPS? That runs the whole show from gear selection to kicking down to fuel and ignition timing maps.

Did you ever solve this problem? I can’t figure it out.
