ok i just got this problem that started with my car when im on 4th gear going to about 5k rpm the needle stops and starts to go back down and my car slows down also, like if i were to let go of the gas and speedometer stopped working also but my car only acts up once in awhile. its a 92 integra rs with a ob1 b16 ys1 tranny i do get an engine code but its for that jdm vehicle load sensor. any info would be greatly appreciated thanks.
