P2E Ecu problem
All right i was having a problem with my car. ended up the ecu if fried. i borrowed my friend ecu and it worked fine no check engine light.
So i bought one from somebody. i recieved it today I plugged it in and it idled rough and fluctuated around 500rpm. and had a check engine light on.
I put my friends ecu in it and no cel idled fine.
tried the ecu i bought again and same thing idled rough with cel.
So my question is does the manufacture date on the ecu matter?or is the ecu bad?
mine has a date of sept10 1998
my frineds is sept 98
the one i bought is feb23rd 1998.
I jumped my ecu still throws code 65.(rear o2 sensor)
the ecu i bought throws code 15 ( ignition output sensor)
a borrowed ecu dont throw any codes
