hi,
i have a 95 240sx w. a ka in it. this just happened recently, there is a whining noise from the intake manifold area. it kinda sounds like leaking air. if any1 has this issue and fixed it, please let me know how u guys did it. or what you guys think might fix this. please and thank you.
well you could always use the water or carb cleaner trick … you spray it along the intake or vacuum hoses and anywhere you like…if you got a leak…then your idle will stumble a little bit…or in my case it will idle up a bit…it that dosent work then you can cap off your intake and exhaust and pressurize the whole system w/ 5 to 10 lbs of air pressure. Spray everything down lightly with soap and water and look for the bubbles, just like checking for leaks in a tire ive personally tried these techniques and like the cab spray better…good luck
