Which code# in particular are you getting? Where is the bung located that the sensor is currently in? In my old CRX, the O2 sensor was all the way back at the collector just before the cat, with no issues or codes. It takes forever for the older ECU's to switch to closed loop.So I'm still getting a code for my O2 sensor, and the engine is kind of boggy when it's cold. I was doing some reading, and now I'm wondering if I need to move the O2 sensor up to the first bung because it's a 1 wire so it doesn't heat itself. The more I think about it the more that makes sense. That's where the O2 sensor for the D15B2 was, and that's where the one that was on the new motor was before I replaced the header.
It's always a nice feeling to take care of all the maintenance stuff.
You should look into Energy Suspension bushings.. some of the best poly bushings out there!
Did you end up replacing those bushings? I agree that the hard rubber kits are better options in general.I've considered them. I'd kinda rather go with hard rubber instead. Not quite as harsh and doesn't require greasing. Downside is they're more expensive. Hardrace and PIC both sell full kits for my car.
