Interesting...why do RPMs spike, then?

MAF clearning results Didn't notice any difference after MAF cleaning. One wire was black. My MPGs do seem **SLIGHTLY** better, but I've only been through 2 tanks since.

Really? Excuse me for digging up an old topic, but to me it's not old. I just bought an 07 and this downshifting while coasting on level ground is absolutely ridiculous. Granted, yes, it makes sense for downhills, but not while coasting flat. Has no one figured out a way to disable this? I...

Yes. Actually, it was the dealer's mechanic that claimed to have taken off the belt as part as his diagnosis. He was suffering from cranial-rectal inversion...

Partial resolution Some good news; The "whine" turned out to be just the idler pulley. The "hyperness" and downshifting still persist, however. I plan on doing the MAF cleaning tonight, as it sounds like that might help. To my knowledge, it hasn't ever been done (currently @90k miles). I'll...

Issue Resolved I took my truck to another mechanic. Turned out to be just the idler pulley. The dealer doesn't know his a@@ from a hole in the ground.

Actually, I believe the dealer changed the engine oil and filter just before I bought it.

I came across this article on narrowing down torque converter and transmission whine noise. Symptoms of a Transmission Oil Pump / Torque Converter Diagnosis Thinking of checking the transmission filter... Also, wondering why there wouldn't be any idiot lights going off if the transmission pump...

progress4m, So, it sounds like the water pump is not driven by the timing chain, unlike the timing belt engines? I guess that would just leave the oil pump/gears. They said they used a tool to hear where the sound was coming from (they called it something like a sophisticated stethoscope) and...

salong53, funny you should mention the torque converter. I just took my 4runner into the shop for an engine "whine" that developed recently. A possible faulty torque converter was on their list of causes, in addition to oil pump and transmission (they removed the serpentine belt to eliminate...

chuntmd. I will try this for sure. Thanks for the idea.

I looked into the price on this recently at a Best Buy and it was about 500, but had alarm too, I think. They said that their car radio install specialist weren't "trained" on this yet and that there was some ridiculously long sounding training period they had to go through to be able to do it...

Greetings! My 07 4.0 4runner (90k miles) has recently developed a "whine". Tested by taking off serpentine belt, still whines. Dealer thinks it could be a faulty oil pump. Couldn't it also be water pump or pulley(s)? The only reason I can tell that they jumped to this conclusion is that they saw...

CXS, which issue specifically has a fix in the Rav4 forums? Any idea what they're calling it? I can't seem to find anything over there. Thanks!

Thanks T-Man. That's is what I'm beginning to gather. Sounds like I may have jumped to the conclusion that this was abnormal. I just miss the melow-ness of my 02. However, I'm not sure I can get past the downshifting automatically on downhill or slow-down. Makes me nervous to think what this...
