exactly go to part source and grab some hose should be super cheap, and it doesnt hurt to have new hose anyways…
I have same problem…when start at cold my rpm stay at 2000rpm, start driving and disengaged the clutch my rpm goes up and down and when its hot back to normal 800-850rpm. Also when came to stop my rpm drops to 200-300 rpm and goes back to idle 800-850rpm. anyone solve this problem?
