Welcome to ZDriver!

Do you mean the engine won't go over 6000 RPM (revolutions per minute)? Hopefully you aren't rev'ving the motor over 7000!

 

helo

engine torque goes to 6500, then engine stops and wake up on 6000 an goes to 6500 and again and again. i forgot to say that check engine control is shining but it often shines when i buy gasoline. what kind of gasoline i shoud buy 95 or 98 I don't see any information about this.there is only written "pb".

 

sounds like your hitting the rev limiter. lol. i dont think the engine is supposed to ever rev over 6500, theres no need. it's not a problem with the car from what i am gathering. also, 95 will probably be just fine on a stock engine

 

but every time when i buy 95 check engine i shining. probably gasoline is low quality

thanks everybody for help

 

that is strange. if one gasoline type sets off the check engine light and the other doesn't stick the other. but yah the car shouldn't even go over 6000 rpm to be safe.
