I have a 79 Rx7 and just bought Racingbeat headers and had them installed. When the headers were put on, the thermal reacter was removed of course and the already non functioning exhaust pump was also removed. This led to me having a aav(i think) soleniod switch hose with no where to put it and the car runs like crap and cant idle on its own, any ideas???? Help!!!

 

Sounds like u have a massive vac leak.

 

Have you thought about plugging the hose?
