Question regarding ECU resetting
I been having some CEL problems as of late and it requires for me to reset the ECU when I think i have solved the problem. I have noticed when i reset the ECU and wait about 10 mins which i always do that when i turn on the car afterwards it would have a very weak idle and one time i disconnected the postive and negitive from the battery and it just stalled. Is this a normal thing for all of you that have a IS 350? Thanks.
Im currectly getting a code p0171 and p0174
