    Engine Idle pulsing randomly - head scratcher

    Wow I can't wait to see if that's the problem with mine! I bet it is. That hole is a lot smaller than I thought it would be. Congrats!

    Engine Idle pulsing randomly - head scratcher

    @ Pop If that doesn't fix it for you, check you TPS. Mine is so out of whack. I turned it all the way down, and it's still metering to twice what it ought to be. It's a lot simpler and cheaper to replace, plus it will take you about 20 minutes to check.

    Engine Idle pulsing randomly - head scratcher

    @ Moustache- I checked my Dashpot, and it looks fine. One thing I didn't like was that it seems like there is some play in the 'Throttle Positioner' which is opposite of the throttle body, and controls the butterfly within the Throttle Body. The thing I didn't like was that it didn't quite...

    Engine Idle pulsing randomly - head scratcher

    So here's my latest update: Yesterday I was killing some time before it got dark- this time of year it's 4:30 in Washington. I was metering some sensors that have been on my checklist. My vane airflow meter was spot-on. Then I metered my TPS (Throttle Position Sensor), and it was way off. When...

    Thanks Moustache. I am going to go look at mine right now! My 'dashpot' is still intact, and looks very good. I couldn't find anything in my manual for it. Let me know of any other resources you find for this piece. Thanks

    Surprisingly I've heard this solution a few times. I will make sure, but I am pretty sure my coolant is full whenever it does it. I take it you're talking about within the radiator itself, and not in the reservior?

    Thanks for the heads up. The only thing is that my friend as a '94 with the V6 and it does the same thing, and his head gasket was replaced two weeks ago. Does yours still do it?

    Engine Idle pulsing randomly - head scratcher

    Something I noticed the other day. I drove to the top of Mount Ranier in Washington state, and it idled perfectly at the top. Usually I am at sea level- I live on an island. I'm curious if we have a air pressure sensor of some sort... I'm about to go and replace my upstream O2 sensor. Will keep...

    Engine Idle pulsing randomly - head scratcher

    It has to be a sensor. I just can't see those valves failing in there. They're all so simple. Has anyone tried the O2 sensors? I just bought one of them, and I'm going to replace it. I also find that when I put the 4Runner into gear, out of park, the idle varies much more greatly, sometimes...

    Could you explain a little bit more? Do you know exactly what they replaced? I'm not familiar with what a baffle is specifically. I've heard of dirty throttle bodies causing this.

    Engine Idle pulsing randomly - head scratcher

    I have a question about your problem. Does it idle that way when the engine is cold and hot, only cold, or only hot? Does it seem to be a particular type of driving, like city verses highway? I'm having a similar problem, but it's intermitten.

    engine temp gauge reading

    Of course check the coolant. One thing my dad has always said in this situation, is to check your ground wires. When you start having electrical problems the easiest thing to do is to check all of your grounds and then check all electrical connections. See what that does. How was the 4Runner...
