no because that will erase the code.

try again.

 

Anyone know why i would b e throwing a 91????? Can my ecu be bad?

 

If you really can't figure it out, Autozone will read your codes for you.

 

i know how to check an ecu, but for some strange reason its throwing a 91. Should i get a REAL obd2 diagnostics machine to check it? instead of using the paper clip method??????
