Can anyone identify (in detail or photo)? I have heard of DIYers using the brake booster hose to spray valve cleaner with better dispersion than thru the trottle body. Each time I tried thru throttle body I barely get smoke from tail pipe. Hoping to do this to help with misfires I found using torque logging for cylinders 1 nd especially 3. Or should I find a mechanic simply cause the brakes are involved?
