Hi Bryan, this is not easy for the inexperienced, you might want to take it to a qualified tech. Basicly you have to remove air cleaner and backing plale, raise fuel tank in the back or as necessary to gain acess to throttle body and intake manifold, then disconnect all cables and wire connections and fuel lines. The injectors are located in the intake manifold held in place by the fuel rail. Your going to need new o-rings, clamps, and seals in addition to the new injector. Good luck.

Btw, I’m available to help over the phone in case u need at

SOURCE: throttle body injectors not fiering but there is fuel pressure

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

SOURCE: 05 Impala missfire code 301 have changed

check intake for vaccum leaks,the gasket also and egr valve, thats alot of parts to have replaced without diagnosing first, if there are no fuel leaks and you said all injectors were replaced then you have a defective fuel pump, also these engines had misfire problem because of dirty injector but you replaced them so count that out. good luck.

Why is there no throttle response and the engine light is on on my 2010 HD FLHTCU 96 ci ?

You've got to twist the grip HAHA ! Seriously, you can do a test by yourself, press the trip button on the speedo, with the ignition off. One second later (keeping the button pressed) turn the ignition on and you-ll see a self test on the speedo. After the needle pegs and all leds come on, you'll see in the counter area a type of code. Using the trip button again you can read the ecm and tsm modules errors. Just press and hold the trip button as you go along. In one of the fields an error should come on like "P1005" or similar. You can look it up on the net. There is also a TSB out on the throttle TT-418 there were issues with the terminal connections at the throttle body.

Fault code po262. have changed injectors twice. checked wiring. looks ok could it be ecm

P0262 = Front Injector High EFI

One thing you can try is to swap the injectors front to rear, and see if now you get a P0264 error code.
If so, that tells me that the injector itself is the problem.

Sometimes one of the injector wires can break inside of the insulation and the wire will look fine.
You might try wiggling the injector wire while the engine is running and see if you get a code.

Trottle cuts out on 09 ultra classic hd

There's probably a sensor in your throttle housing that regulates the amount of fuel that goes through the throttle body to the engine. The sensor could be located on the throttle or you may have a bad throttle body. There are computers on both ends. I believe you ought to call the dealer and find out

Harley p2176 solution

DTC P2176 = Throttle Acuation Control: closed position not learned (2008-2009 models)

Remove air cleaner and check Throttle Body inlet for debris or mechanical interference restricting movement of throttle plate.

If none is present, replace Induction Module.

If present, clear obstruction, clear code from memory.
Start engine, operate throttle several times.

If code does not come back, system OK.

If code reappears, replace Induction Module.

leaky injector/s is flooding motor, mechanically clean or replace. And clean throttle body while you are at it with spray cleaner. Should be almost spotless where large throttle valve opens and closes.
