Guest jeremy Posted January 25, 2010 Share Posted January 25, 2010 hey ive had my na supra for a while now, and a few months ago it started playing up when i start it,, i turn the key to crank and it fires up but struggles to build revs from crank and takes about 2 secconds to get to 1-2k, i can encorage it by opening the throttle.. i asked a mechanic about it he said it might be a vacuum leak and told me to pump the brake pedal on start, i didnt notice much of a difference can anyone help me? i hope its enough info Quote Link to comment Share on other sites More sharing options...
miko_supra Posted January 25, 2010 Share Posted January 25, 2010 Idle control valve sticking possibly. Take it out and give it a clean. Does it alter whether the car is hot or cold? Quote Link to comment Share on other sites More sharing options...
