Hey guys I just recently purchased a 1991 mazda fc rx7. The question I have is that the car is bogging down on power in thrid an fourth gear almost as if it was going to stall out. I havent replaced the fuel filter or pump yet but i was wondering if thoes two reasons would be the cause of that happening in thrid and fourth. If you guys can give any info or help it would be appreciated.

 

Check for error codes first.

 

Thanks i will be sure to check that asap
