Hi, I have a 93 rx7. Last night I put in a new battery in, started it up and while it was idling, the idling went from 1000 rpms to around 600/700 rpms. The engine is rocking pretty hard in the engine bay, the tone is a lot lower than before and it doesn't pull when I tried driving it earlier. I have no idea on what the problem could be so I'm hoping someone else will have a clue.

 

Anybody have a clue?

 

Hi,

How di dyou go with this?

What was the issue?

 

Turns out it was just some vacuum leaks, I also put in new spark plugs.
