Hey guys, I recently bought a 99 si, it has a b16a2 wit a obd1 gsr Ecu, I decided to put the stock si Ecu, obd2b, on the car but I immediately got cel p1337...it was running ok for a few miles but now it stalls as soon as I turn on the car, ifi press on the gas it stalls evrn faster...the gsr ecu still makes the car run ok...could this be a wiring issue? Btw the gsr Ecu is chipped, don't know with what...thank you!

Thanks yea I caught that too, strange thing is I no longer get cel light, my car just stalls...

well than if there is no cel then its something mechanical have you disconnected the battery for like 20 minutes

If you don't know what the ECU s chipped with then why are you running it? Get a stock ECU and try that.

The si runs with the chipped ecu, but not the stock ecu
