I have a 89 civic hatch si that keeps on droping rpm's and some times die after hiting 55 to 60 mph when in fifth gear and once and a while the voltage light will flash on and off I do have a bad clutch but that was ruled out as a cause by a friend of mine who has a civic hatch as well does any one have any ideas of what it might and what I can do Email me at Jetoutant@yahoo.com

 

How is the car at idle ? Is it rough or normal ?

 

It idles normal

 

the Idle is normal

 

Does it ever die any other times ?When it dies, do you let off the gas completely or are you still on the throttle ? And does it just shut off or sputter out ? Also did this just start happening or did it happen after you did something to the car ? Any more info ? You might want to take the distributor cap off and inspect the inside and clean the cap up. Also check all your connections and vacuum hoses.
