My motor is not running right
Hello everyone,
I new to the rotary world with my first RX7 FD I purchased about 3 weeks ago. I was on my way back from work today and while driving on the highway I stepped on it once I finished my run I noticed that the car was running rough I continued to drive normally but is I got off the highway and got to a stop light the car was idling really rough almost like if there sparkplugs not working or something. I got home and got out of the car while still running and idling badly yet there is no smoke what so ever coming out of the exhaust. I just wanted to for tips on what I should look for/check.
any help would be greatly appreciated.

Thanks for the info, I checked this morning and found nothing out of order. I'm going to check compression this afternoon (hoping it's not the motor as it was rebuilt about 60k ago I would think it would of last a lot longer than 60k).

Thanks, unfortunately, the front rotor has no compression so I need to do a rebuild. Since I'm new to the rotary world I have no idea what a short block is in comparison to my motor. All I know is that I have a 93 rx7, how much are you selling it for?

Mazda still sells these motors, Ray Crowe at Malloy Mazda sold me one about this time last year, cost is around $4300 plus shipping, and it is a "brand new" not rebuilt or remanufactured motor. my motor's compression numbers were 110PSI and 120PSI (I have video)
You can save yourself some money by going with something like what I have, though consider the eventuality that even that motor will need work at some point. let me know if you have any other questions
