so i have an 1987 supra turbo, i upgraded the turbo to an hks sport...did the whole 3 inch exhust...electronic boost control...now been driving it for a while have this weird/tricky problem..... when the weather is dry, runs/idles perfectly, but when it sits in the rain over night, and i drive it, until the car runs for about ummm 15 minutes the idle is rough and sometimes stalls....before it stalled the check engine light goes on, so i bought the code reader and it lead me to CODE 13 .... meaning rough idleing due to cam shaft sensor/ecu and a whole bunch of other stuff... i am thinking that the cam shank sensor is getting wet and until it dries up it is affected...if thats the case, i cannot find this sensor to have a look at it....if anyone has had this problem or knows were i can locate the cam shack sensor in my car, my troubling days will be over... email me (
kindhart14@hotmail.com) or post it....thnx a lot
