Idle Fluctuation, Failing Turbos, PRoblem???
 

Well it seems my car will idle around 400~900RPM and sometimes even stall. I do not get any response from the turbo's, they do not engage at all. I was looking around and I heard that it would be an Apex Seal or a solenoid that came loose. THe car looses all power when the turbo's try to engage. IF you know what hte problem is, or how to fix it, PLEASE PLEASE let me know! I greatly appreciate the help!! -DArren-

Forgot to mention... it's a 3rd Gen, 1993 RX7.

Check the vacuum line to boost sensor.

I'ver been chatting with this guy. The first problem was that his MAP sensor line popped off. Now it still has a little rough idle that he is working on.

Sorry about that.. yes it was the MAP sensor that caused the fluctuation and boost problem. Now... it's idling rough. I think I might have a problem with my primary turbo failing, but if that was the case, the secondary wouldn't boost at all right? since the primary has to work in order for the secondary to get a proper boost... I did find a few busted vacuum hoses, and a busted vacuum switch, looks like it's time to replace all these hoses. Fixed one problem... on to the next... *sigh* it's a neverending process.

might as well just go through and check/replace all vacuum hoses just to make sure that couldn't be the problem.
