Up until, what?

Up until, what?

...up until...it stopped running fine. :whoo:

Up until I developed the skip/ miss under low rpm load

I would get a mini VCI cable from eBay, which will come with a pirated version of techstream (same thing Toyota dealer uses) to diagnose the problem.

Maybe try some injector cleaner, one might be partially clogged.

May also want to check coil pack starting to break down

Probably gana buy 1 coil pack and swap 1 out at a time and hope I can find a bad coil pack . Can't use the cable because I do everything from IPhone and got rid of Lap Top a while ago . My man has a Genesis Scanner , might that help ?

Not familiar with that one, but just about any OBD2 scanner will at least give you any stored codes. I would definitely give it a read.

Put on scanner today , no codes

Maybe if you can find someone with techstream you can try to see if there are any stored codes and/or Toyota specific codes that only techstream can read?
