ok i have a 1995 gsr n i just replaced the valves cause i over reved the engine n stuff but when i went to turn the car on it was ok it even idled right so i turned it off n when i went to turn it on again it started to idle lower so i turned it off and checked it out well i did this like 3 more time and everytime i did the idle went down now if i rev the engine n try to let it idle it shuts off and it can bairly keep idle now what the hell is wrong with my head!!!!!!

 

bump!!!!!

 

bump for a man that needs his car to run!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Try raising the idle. Idle speed is higher when the car is cold. It drops as engine temp increases. If it idles smooth i'd give that a shot. Remember to disconnect iacv and reset ecu.

 

sounds like your exhaust valves are too tight...do a valve adjustment and see what happens. it should help alot.

.06mm-.07mm on the intake valves,

.07mm-.08mm on the exhaust valves.

im assuming you can do it yourself, but if you cant, get someone to do it for you and ALWAYS MAKE SURE the engine is completely cooled off, i.e. do it in the morning before you drive it.
