I just installed a 94 rx7 motor, into my 93 rx7, everything runs fine, but today after I had a shop put freeon into my a/c system for my a/c to work, now when the gas pedal isn't pushed down, and the car is just at idle it dies, the shop said that maybe it could be the alternator that it may be weak, the car has never died before this is the first time its done it, please if anyone can help or had this problem let me know thanks.

 

They probably overfilled your system. THe same thing happened to me a while back. Just unscrew the highpressure cap, put a rag over it and press the valve core for a few seconds to release the excess. If it doesn't work then do a little more.

 

thanks
