I have a 95 EX with automatic trans, at high speeds(88-130mph or so) under full trottle, in 4th gear the engine rpm fluctuates as much as 1000rpms, it bounces back and forth. It gains speed while it happens so I know it is not a rev-limiter. The car is mechanically fine. The only power adders currently on the car are a genaric short ram intake(all the proper hoses attached-i.a.r. and a clean filter) and a fake medallion style muffler. I just would like a little info(aside from slow down ) to resolve the issue, if possible Thanx---------------- NoNo

 

any help, i just would like to know what might be wrong, that i can't find-----thnx No-No

 

check your water temp sensor and your termostat to make sure that they are working properly
