OK we currently pulled out my OBD1 LS swap out of my eg hatch. And I replaced it with a 99 GSR swap. It dropped right in and everything plugged right up. Except for two plugs, one on top of the manifold(???) and another I believe which is for the 2nd 02. I only have the LS ecu to run on for now. Will that be possible just for a week or two? When the car starts it gets a very low idle at initial start up and when I tap the gas it also goes low right before it goes back to around 7-800 rpms. I also get a solid check engine light (ECU right???) But once I turn the car off no more check engine light, I only get it when the car is running. IM still using the obd2 dizzy. ALso when the car starts I get a constant intake suction noise, does not sound normal. Could we have the throttle cable adjusted wrong?
