this may seem like a dumb?? but when you flash a code 10 does the ecu flash 10 times then stop for a sec and flashs 10 more..... is this a code 10 or a 20?.. mine flashes 10 stops then 10 stop then 10 and so on i thought its a code 10 maybe it`s a 20 .. any idea

 

It's a 10.

10= Intake Air Temp Sensor - Engine performance prob
20= Electronic Load Detector - Charging System prob

If it flashes 420 times, that's something all together different
