How do you adjust the idle on a 2007 rav4

I changed my plugs and gapped them properly, put a really good fuel cleaner in, I use plus gas and sometimes when I come to a stop the car seems to idle to slow for a few seconds. I wanna adjust it just a little bit, how and where do I do it

Starts but won't run


Good Morning Alex

Your question is shy on specifics, so I'll cover some broad things that can cause your engine to quit, or run roughly.

A running engine needs three things to arrive smoothly, and in a synchronized way: Fuel, Air, Spark. It also needs something to get it moving at the start, but you said it'll start, so I'll leave that alone.

If fuel isn't arriving like it should. Things to look at are:
  1. Old or clogged fuel filter. If it's been a while, or if you have no idea how long it's been since the filter was changed, this is usually an easy fix. New filter will have much less resistance to fuel passing through.
  2. Old or clogged fuel injectors. (Possibly a carburetor issue if the car is pretty old). If the injectors are clogged, not enough gas gets squirted into the cylinder. You can start by running a bottle of fuel injector cleaner through - add a bottle when you fill/top off your fuel tank. May take a couple tanks, and this won't help much if you can't keep the car started and running long enough to run the gas+cleaner through your injectors.
  3. Fuel Pump. A bit more involved, but the pump could be old, or, more importanly, leaking. A leaking pump, or fuel distributor, can be really dangerous. if you smell a lot of raw gasoline smell after trying to start, you'll want to get this tracked down ASAP - uncontained gas in an engine compartment can lead to a fire, big time car damage, and significant risk to your safety.
  4. Bad fuel. Sometimes you can run across a shady station dumping other (ahem) additives, or even water, into their big fuel tank. The wrong stuff can make your engine pretty unhappy. If the car has a preference for higher octane fuel, you might also consider a bottle of octane boost (most any car parts store). That might get you running and able to run the injector cleaner through and/or burn off the old or bad gas.
If there's no air, most likely you have a dirty / clogged air filter. Google for videos on how to change your air filter, it's usually pretty straightforward. Look at the current filter. if it's really dirty, or clogged with oily gunk, you'll definitely want to put in a new filter, and possibly try to track where oily gunk came from.

if there's no spark, it could be the coil(s) for the plugs being old, dirty, poorly connected to the electrical, or not attached to the plugs properly, it could be that the plugs are mis-gapped, damaged, disconnected, or fouled. Start by looking up the procedure to remove a spark plug on your make/model. Look at the electrode. Is it intact? Does it have the proper gap (you'll need a spark plug gauge). Is it covered in oily residue? (this may mean your piston rings are getting worn and letting oil into the combustion area). There are a lot of other possibilities and diagnoses - you can see more here

Spark Plug Analysis


Your manual will probably have recommended intervals to change out the plugs, it's not a bad idea if you're past that gap since the last change out. eBay is a pretty good place to get reasonably priced new plugs if the cost of the replacements is steep - (in my case, my Prius uses iridium plugs that can retail for $15-20 a piece, or were found on eBay for about $32 for the set of four)

pay attention to the part of the spark plug guide that talks about plugged PCV valves. This is another inexpensive part with a wide range of ease or challenge to replace on different engines. That may make a difference too.

Hoping that this may help!
Good Luck

My toyota rav 4 2002 model consumes alot of fuel any ideals as to what the problem might be


When was last tune up? Plugs, wires, ALL filters & fluids especially fuel filter. I'd start there and run a good fuel system cleaner through it and AVOID cheap gas.

Hi, I have a 2006 Altima with 31,500 miles. Recently, the engine start shaking when car is Idle but I still feel the shake when driving or at red lights. My second problem is a weird loud (humming) noise...


You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)

Stall out when given gas to excellerate ... runs fine in idle


For all those out there that have had problems with your Chevy Aveo Stalling, inconsistent idling, hard to start, or throttle problems, Hollywood Harv has the answer for you. Try a new Valve Idling Air Cont GM part number 93744675. You only need one and it has to be install by Chevrolet so they can place in the codes to make it work properly. Toss the old one away as most likely has so much carbon build up on the part that it stuck or struggling to function properly. It worked on mine after many different attempts at other stuff! This is a sure winner! Good luck and drive safe! Hollywood Harv

Misfiring when accelerating at highway speeds in fifth gear


It could be a couple of things.
1) Check to make sure the wires are in the correct firing order.
2) Check to make sure th plugs are still good, including the gap.
If these don't work than you should probably have a mechanic look at it in person.
