After replacing a butt load of parts and all vacuum line she still won't idle worth a crap. Then after going on line and finding out what each component does and how the work I tapes the hole up for the BCDD and now she idling down to 850 so thinking that been the problem all along. So where the heck do I find new parts for it or can I just take it off all together

Check the AAR when she was hot and it was closed. And no leaks from the bellows. If I disconnect the hose that goes to the PVC valve the rpms drop but if I plug the hose they shoot back up PVC valve was replaced last month and it has suction when the car is running.

Ok I've plugged off every vacuum port and hose on the car and checked and replaced the hose from the airflow meter to the throttle body and it's made no difference at all. She still idles way too high. She doesn't smell rich either just won't idle normally

I forgot it's a 1977 280z with fuel injection

Ok I love my Z but this is crazy. She's been running AWSOME but all of a sudden she won't idle below 2200 rpm. I've texted the sensors have great fuel pressure checked the fuel regulator and the cold start injector. Everything looks fine but yet she won't idle where she's supposed to. Anyone have a similar problem and knows how to help I'd appreciate it.

I need help with a 1977 280z. All the vacuum lines on the car where messed up and disconnected when I got it and I can't find a diagram anywhere. I guessed on a few. The car runs great for a minute then like garbage then great then garbage. It's really hard to start when she's cold and the rpm's are at 2000 until it warms up. It's not a CA car and has a 5 speed. Anyone know what the heck is going on
