06 Toyota Highlander momentarily cuts off

[MaximaGuy]

06 Highlander cuts off and then bucks when taking a 90 degree turn - it almost feels the fuel just cut off. No codes but the vehicle just runs fine - changed the air filter and cleaned the MAF. Yet to tackle the TB gunk but is this symptom related to anything related to the fuel filter - oh also getting 1.5MPG less in the past 3 mo.

Any suggestions where to start understanding the problem

When this happened to my Volvo it was because of a failing fuel pump relay. When the same thing happened to my Mercedes it was because of a failing ignition key. Whatever is doing it to your Toyota, it is more likely than not an electrical issue.

90 degree turn in any direction?
how much gas in the tank?

What engine?

Intake boot torn and getting stressed in a turn making a vacuum leak?

Turning right alone and not when turning left. Good question

quite old + how many miles + how it was used, BUT at that stage of life many things it could be, a job for a pro with lots of experience with your ride, if its worth fixing, good luck!!!

Two choices

2.4 I4 (2AZ-FE)
Or
3.3 V6 (3MZ-FE)

Hybrid models had the V6 IIRC, with extra Hybrid synergy drive add ons

Oh its the 3.3L non-hybrid AWD vehicle

It has 220K miles on it and babied all throughout its life - infact the car is only worth 2K but I am putting 1K into it for full front end replacement. I trust this car more than anything - my wife wanted me to drive to the FL Keys with our MB GLE, I said no, I would drive this though, she said no - we are flying to the keys. I have complete faith in this car given its been w/ me this long
