I ordered 2x shift solenoids (the over drive solenoid was $$$) and the transgo kit. Really hoping this does the trick.

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
