i was driven down the highway as usual from school an a mustang pulled up by me (indiana highway speed limit 55) i was probably goin 60 well we took off an as usual i was beating him in my 1998 rs an it cuts off at 100MPH very unusual it always used to buzz around at 125mph it felt like a fuel cut off or somthing does ne one know what the problem is ? i use the middle octane which is like 90 or 91

 

Based on what you described is sounds like your engine was starving for fuel. I would suggest looking at the fuel filter and perhaps any strainers that may be present in your fuel injection system.

thanx that could be it since i dont know when the last time the filter has been changed

 

i also been putting fuel injection cleaner in it i know sometimes thats bad for some injectors

 

hmmmm.....fuel starvation, hmmm maybe too rich? lean?? time to upgrade the ignition. more fuel , more power. but you need something to burn those fuel, aftermarket ignition will help.

 

wow what kind or rs you have that goes up to 125 mph hour because i had a rs too and the governer kicked in at 120? now i got a gst way better get a air fuel guage and see if you are running lean or maybe you need new injectors

 

lol...maybe a nitro powered rs..
