Hi everyone, I bought a new Tacoma SR with V6 in February, and it has 7,000 miles. I have noticed something that is happening when the engine is warm, and I am doing stop and go driving. Between about 15 - 45 mph, and especially when the truck is changing gears, I am getting a pinging sound / spark knock upon acceleration. It's difficult to do a video, as it's most noticeable when the windows are down, and there is too much wind noise for my phone to pick up this noise effectively. I run Shell gas, 87 octane in this (since day 1), and I've heard others say that they used 91 octane to deal with this issue, some have talked about the knock sensor, etc. Anyone deal with this, and any solutions that you might recommend? Thanks very much!
