Bad MPG. Need help 200mil to tank

[cloudasc]

Thanks guys for your help.

The name of the seal I believe is called "Injector O Ring", and if you need to replace one, replace them all.

I think there are like 3 different o-rings for each injector. While you are at it, might as well do the others. I have done mine when I did the EGR cleaning but it's like over a year now.
Pretty easy but gentle is a must and lots of rag for gas.

i was getting the same mileage as you and i also only buy shell plus. stock f22a6 automatic with AEM short ram. i did the fuel filter and O2 sensor waiting to see how ill do on this tank. could it be that the h22 swapped CBs get like 350+ miles on a tank cuz of the Vtec??

still getting bad MPG guys. Even though I fixed the 4th leaking injector.. Now this leads me to change all the injectors. Even though the injectors are almost around 200k miles.

Have you checked your ETC like i said? If its bad, itll tell your ECU that your car is still cold when its already up to temp, causing bad mpg, which seems to be relatively common for our cars.

Engine Coolant Temperature??

Is it this?

Its one of those. I think its actually the one on the left of it.

Do not change all of your injectors (unless it is your only driving vehicle and cannot wait a few days while the car is down) I sent mine into a shop to be cleaned, cost roughly $80 and they give you a full report on how your injectors preformed before and after the cleaning, they also replaced the filter and all the o-rings/gaskets. The turn around time of the shop (right at the new year) was only a week, their website said 3 days.

It is a cheaper alternative that buying new ones, or buying junk yrad ones that who knows how they will run.
