Flashing/Blinking Check Engline Light CEL! HELP!!
I have 02 WRX that is a stage 4.
I recently built a 2.0/2.5 hybrid engine + installed FP 68HTA turbo + electronic boost control with EDO performance
Suddenly one day My CEL started to blink/flash on occasions.
Now it is solidly on but still on low RPM's it still flashes then goes back to being solid.
The blinking happens on low RPMs..
I thought it was a indication of misfiring but the codes that are thrown have nothing to do with misfiring.
the codes were...
p0500 basically not started genereic code
p1518 Starter switch circuit low input
p1591 Neutral position switch circuit low input
p0131 Front oxygen (A/F) sensor circuit range/performance problem (low input)
p0132 Front oxygen (A/F) sensor circuit range/performance problem (high input)
I read a few threads that said it might be my green test connectors but they are NOT connected!
It cant be the test connectors.
Before this flashing CEL, I've been stalling on random occasions especially when i down shifted..
Can this be related to this problem?
I brought it back to EDO PERFOMANCE, they told me it is probably a gounding issue because I also get the Exhaust Gas Temperature COde, which I've disabled long time ago but it still comes out!
but I dont know if i can believe it is a gounding issue..
Even if so, I dont know how to fix this problem.
Again, it isnt the test connectors or misfiring cuz my car feels and runs fine.
I really need some help..
please help me..
thanks in advance.
