I bought a 87 rx7 a few weeks back and it was idling rough, so i did a compression check, front rotor around 95 to 100 lbs , but rear was just around 60 all the way through. Probally means rebuild i guess. But forgot to have wife hold throttle pedal down and didnt pull fuel breaker, any ideas on what to do next

 

Do a proper compression test.

 

Could make big difference holding gas pedal down so butterflies are open, i guess

 

yeah u'd think so but holding the throttle open really makes no difference.
