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?
Welp back to 11.x mpg city n dash. Assuming due to torque reporting misfires on cyl1 and 3 (no codes ever). Guess gonna buy 2 new plugs since the new plugs have anti seize coating already applied. I swapped old plugs for rodinium ones while I had the engine torn down. Thinking need to check for fowling or gap? Or swap coils to diagnose.
