Fuel Injector cleaner is really advisable to use?

Use some wheel bearing grease on the O-ring before you install it. Rotate the injector slightly as you push it in.

Depending on the grade of fuel you used just run it down to empty and refill with correct grade, as long as you did use diesel or racing fuel youll be fine, and unless your hearing any odd noises like a pinging your fine, I also wouldnt suggest using fuel injector cleaner it doesnt really do much unless you use it reguarly

You have clogged an injector, isloate the injector and replace it.

Hi!!

You should be using regular unleaded. This is "regular" 87-octane gasoline. You have no reason to need gas with a higher octane, it would be a waste, stick to 87.

Good luck!!

HELLO you don't need to replace injectors unless you have one completely plug, Just get a pressurize fuel injection service done that will bring your injectors to top shape . hope this helps

1996 fuel injector corolla idles at 1000rpm on start-up.when i stop at a robot or stop street it idles at 500rpm and have to feed it petrol to stop it from switching off.tried fuel injector cleaner but this does not solve the problem.

Get you a can of SEA FOAM at a local parts store
be sure to read the directions before you buy it.

Possible fuel delivery problem, fuel pump, fuel line, clogged fuel filter, leaking injectors or injector O-rings, faulty pressure regulator etc. Check your fuel pressure.

I had to do some digging to find this info: The code is P2716, which is a problem with the 'transmission pressure control solenoid D or it's circuit.' It is located on the transaxle valve body. There apparently is a technical service bulletin (TSB) # 1406 concerning this. If your Corolla is still under warranty, the dealer will fix it, which is, according to what I could find, replacement of the computer that controls the transmission. The bucking problem you described may have actually been a transmission shifting problem, a symptom of this code the cars computer threw. If you did get some debris drawn out of your gas tank due to the low level, the injector cleaner might help, but it has nothing to do with this code. I would recommend you have the fuel filter replaced (to address the low fuel tank, possible debris drawn into fuel line issue), and check w/ the dealer about the TSB, it covers '05 thru '07 Corollas.
