Hi guys, I just turned 100K miles on the RAV4. I changed the spark plugs at 90K, but didn't have any adjustments made. (Tune up) Now, it's still running fine, but I notice that when I'm going slow (1200 RPM) and I just touch the gas pedal, to maintain my speed, the engine vibrates lot, and sounds rough. It didn't do this before, it ran very smoothly. Do I need to bring it in to Toyota for an adjustment or something? This minor problem started a couple thousand miles ago, long after I changed plugs
It still keeps running, but I find it annoying...it's just not right! I hope it's just a simple adjustment. It's way out of warranty, and I don't want to change a computer ($$$$) for this little problem.
