> [@stmotorsports](#): > > am i to assume this means you have a JRSC on the car? if so your bypass valve could be stuck closed, such a condition will cause similar behavior as the engine is trying to idle on boost which is no good No the bypass is still there…But maybe it is fucked up… Hammer time. The elbow is the just because I have no stock tube and my current intake setup has the same form and function as stock ---

> [@Jeller](#): > > x2 Little update would be nice… > > Jeller \<3 Orignal AFM was flat out fucked up. Pulled it apart had a loose wire and one broken point RX7 AFM the flapper spring was very tight. Tiny miata motor could only move the flapper above 2000 rpms… Loosened it up and fixed the connections on the other maf. Now both work. 😃 ---

the spring is for a/f. the position of the feelers on the board , adjusts pulse width… get the spring where ya want it then add or reduce with the other peice more volts is higher , less is lower… [Previous page](https://forums.speedlife.net/t/miata-wont-run/44515.md?page=1)
