Its a 98 usdm gsr motor in a 93 cx when it turns on its fine for like 45 seconds then it will go down a little bit and start makeing a noise like put...put...put...put and so on. then i rev it up not even past 5 grand and it will go back down past 1 grand and it feels like its about to stall out. may something with the distributor or sensors or ecu. please if u have any info that could help please post.

 

any cels? then you might want to adjust your idle air screw. only do that after yuo check the basics. cleaning the iacv,check for vacuum leaks,and so forth.
