I fıt cooss cams 3 months ago and fıt rallı art engıne mount to my car but after ı fıt car gets very vıbratıon to cabıne and ı got ıdle rpm 850 rpm to 1050 rpm for vıbratıon problem.after thıs operatıon every 5-10 days check lıght on when ı get battery cable of than start ıt get normal bu today ı went to servıce they made some tune on ıdle wıth screwdrıver after that tune ıdle works engıne check lıght when ı stop ın trafıc every fıve mınutes WHAT DO YOU THINK ABOUT THIS PROBLEM?
1 )CHANGING IDLE RPM 850 TO 1050 FROM ECU WITH FLASH?
2) FROM CAMS ?
3) BLOW OFF VALVE ? (GREDDY)

WHAT CAN I DO?

 

did you get the code for SES light. if yes what is the code? i would take to a real tuner for this problem or dealer.

 

he's in turkey..

i suggest you go to a tuner if you don't know a lot about evo's. Don't go to the dealer

 

you can adjust the idle with the same screw on the throttle body. what is "probably" the problem is your tps sensor

 

one of my friend has evo 9 too he fits hks cams to his car at the same time and he has the same problem in servıce pc shows in diagnos test idle sensor ı thınk ıt must be a value when we tune the idle .my tps dont gıve any malfunction.

 

check engine light should be coming on due to the new cams, idle needs to be adjusted through ecu flash that screw only allows air to com in to the throttle body and raise rpms ecu flash uses the ecu to raise rpm raise the rpm will no longer be set to 850 it will be at 100 rpms or what ever you set it at. for the vibration go into your timing map and set it at lik 10 instead of 7 timing at idle should smooth things out a bit.

 

thanks tech ttp ı solved the problem wıth your help away from 20000 mıles from you
