2001 3.4L Tacoma - hesitation on hot a start

2001 Tacoma DBC
3.4L 4wd TRD
217,000 miles

Well I searched and read a lot about the topic already but would love to hear from anyone reading this now:

cold start on my Tacoma is great. No hesitation at all. Starts right up.

…but if I Go for a drive to the gas station and turn it off for 5 minutes, starting it up again on a hot start, I experience a little bit of hesitation like it’s a bit of sputter or something just isn’t right. Maybe it’s a rich fuel mixture?

has anyone experienced this? It is giving me second thoughts on shutting off the engine if I know I may need to start it back up within 15 minutes or so…

I’ll get a video of it here in a bit…

 

Any codes?

 

No CEL. I have a buddy with a OBD reader. I shoulda thought of that

 

Kudos OP for searching!


Sweet Taco BTW!!

 

You are at the miles when the old Aisin (Brown) fuel injectors start to fail. When they run well on cold start and not good on warm start that’s a good indication one or more are starting to fail.

 

I had the same thing on my old spark plugs before i went supercharged. Had probably 50k km on them and ran like crap when warm. Hesitation off the line and on acceleration. Swapped the plugs (copper ones i think) and that solved everything.
