Thank you ULTRABONGO, I will look into your suggestions. Can you recommend a website or particular manual for locating the vacuum lines I need to inspect? I am flying blind in that arena and my Hanes manuel is not the clearest guide I'm sure is out there. THANKS
I have a 1991 Toyota 4runner V6 4x4, 186K mi. Timing belt replaced once, manuel transmission.
I have a problem that comes and goes. When idling or accelerating it feels like 1 or 2 cylinders are missing. It sounds rough and my horsepower significantly drops. I have changed the spark plug...
