As for injector cleaner? another needless additive as its already formulated into the gas you buy,i've ran my last 4 fuel injected vehicles well over 200k and never used injector cleaner and never had problems with an injector,
Your slight hesitation could be a misgapped plug or a plug wire not working properly or just a bad tank of gas.

I had a Honda Prelude Si once that almost didn't make it home because of bad injectors, had less than 10k miles on it at the time. Probably one tank of bad gas was all it took.
I've seen lots of bad injectors over the years. Cylinder misfire counters and injector fault confirmations in the datastream of my scantool make it easy for me to see them. Lucas injector cleaner fixed two out of the three clogged injectors on the last Blazer I worked on. Took care of the misfire counts on all the cylinders except one...had to drag out the MotorVac machine to clean that last stubborn one.

LOL.... "Research" does not mean for you to research. It's the full term.

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.

Let's stop talking "tomaatoes and tomohtoes"... the point is.. don't let the dealor charge you for it, or at least so much for something so simple.

My bad. Thought it meant to check into before hand. Kind weird though seeing how in my area you cant even get 91 octane.....

your best bet is to just go to a station with certified gas...they dont rate the 87 as far as i know, but, 89 and up are monitered in some companies. less carbon build up the cleaner the fuel you use.

as far as the fuel injection cleaning service, im sure it depends on which dealership you go to. some dealerships and shops i have worked at its a full proccess of addative in the gas tank, liquid cleaner sucked in through a vacuum line near the TB, or a direct injection to the fuel rail, as well as cleaning the MAF and AIT sensors with proper solution and then cleaning the throttlebody.

however, at some shops...it was grab the brakebooster line and shove a hose from a bottle of cleaner to it. some of the "techs" would run the cleaner through so fast it would cause the car to run insanely rich and also blast out the carbon too fast...it would fry or plug the cat.

According to the top tier website:

"Gasoline retailers must meet the high TOP TIER standards with all grades of gasoline to be approved by the automakers as providing TOP TIER Detergent Gasoline."

And thats why its doesnt matter if you buy brand name gas or unbranded gas. It all comes from the same manufacturing plants.

AFA throttle body cleaner - what kind of plastic ( polymer) is our intake made of - I am afraid you put the wrong chemical in there and start melting it. I think there is table on the WWW which show what plastics tolerate what Aromatic HC. We could have Glass-filled Nylon or possibly Dupont talc filled Liquid crystal polymer? I suppose no hDPE ...
