Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hi Im David. are you still getting the codes after replacing the plugs?
ok. give me a sec
ok. i want you to unplug one coil pack at a time with the engine running. which ever one you unplug that doesnt cause the engine to act different is your bad coil pack
its either going to be a coil or an injector. we'll try the coils first.
so the code stayed with #1?
do you have a noid light set?
not so much worried about p0171 yet. ok, no noid light set. do you have a long handled screw driver with a plastic handle?
ok. i want you to put the metal end to the number 1 fuel injector and the plastic end to your ear. start the vehicle and listen for the injector clicking.
any good news?
do you still need assistance???????????
checking in to see how it is going
