1994 4runner 3.0 a/t Last night during normal driving conditions my dash spit a CEL at me, checked the codes this morning by jumping the ei and tei terminals and watching the flash!, two codes stored, a code 14 and a code 25

code 14
GNITION SIGNAL--NO "IGF" SIGNAL TO ECU

--IGNITER/IGNITER CIRCUIT

--IGNITER AND IGNITION COIL/CIRCUIT

--ECU

code 25
AIR/FUEL RATIO LEAN INDICATOR--LEAN SIGNAL SENT TO ECU FROM O2 SENSOR

--INJECTOR FAULT(S)

--FUEL PRESSURE

--OXYGEN SENSOR

--AIRFLOW METER OR MAP SENSOR

--IGNITION

--ECU

The ony idea that i have is that a recentley adjusted my idle speed but a bit to low (idles about-6-700rpm) Could this cause me to go lean an throw a code 25? Can anybody tell me why o would throw both these codes at the same time, and also where i should start with my troubleshooting. any input is greatly appreciated. THANKS

 

After some trouble shooting im pretty sure that ive got in pinned down to the ignitor, but have read that this thing can test good but still be bad, have also read that when the Ignitor sends no signal to the ECM it will shut down the injector? this would cuase a code 25?? : lean??
ANY INPUT IS APPRECIATED

Did you figure out if this was the problem?

 

I replaced the ignitor and coil and have not got a code since

 

so after sometime code free a code 25 jumped back at me again tonight, i am beginning to think that i may have a burnt valve due to the fact that im pretty sure i have a valve ticking(may be injector sticking). Can sombody please lead me in the right direction as to how to trouble shoot these two( sticking injector/burnt valve) thanks
