Anyone know what would make my car 94 civic with a 94 JDM h22a be hitting the rev limiter around 6500 rpm's?

 

wrong ecu maybe??? Or possibly your tach is just off????

 

It just started doing it not to long ago

 

are you getting any check engine lights???? are you sure your tach isnt out of calibration??? have you changed ANYTHING at all???

 

check engine light comes on time to time no I haven't changed anything and it sits around 900rpm's or so at idel

 

find out what CEL code(s) you are throwing.....

 

how do you check the the cel?

 

check your ground under the throttle body! you also may have a vac. leak!

 

look for a pair of wires with a green cover over them, just dagling down by the ecu wires... I believe they have a blue plug... Just jump those two wires with a piece of wire (one side of the wire in each hole on the plug) and crank her up... This will make the CEL flash in the sequence of the code... For example, four long flashes, then three short blips... code 43... Ya feel me???

 

So does it feel like your hitting the rev limiter but you can still go over 6,500RPM or no? Check your CEL(s) before anything else though.
