    Prado 1KZ-TE Starting and Idling Problems

    And about this, the turbo sensor the Toyota service installed was wrong. They installed a sensor for a full size Landcruiser, not a Prado. Just switching the key to ignition already gave a boost reading of about 120, reading should only be around 100 on the scan tool. We installed my old turbo...

    Prado 1KZ-TE Starting and Idling Problems

    Hello guys, an update about my 120. So I took her to the official Denso calibration center after new year. They kept her for a week and now she’s perfect. So it turns out that the fuel pump internals were worn and out of spec. Spill Valve was fine so at least that wasn’t one of the things that...

    Prado 1KZ-TE Starting and Idling Problems

    By the way, does anyone know what a proper MAP sensor reading should be? Mine reads around 150-180 according to the scan tool. I've no idea if that is normal or low, mechanic thinks that it's a low reading. Don't fully trust the mechanic's opinion hence I ask over here :)

    Prado 1KZ-TE Starting and Idling Problems

    Apologies for being such noob! I haven't really had the chance to get to know my engine more. So to clarify, nothing should be plugged in there? And it doesn't cause an air leak? And a little off topic, I see you're from CY. Ti kaneis re? Esy kala?

    Prado 1KZ-TE Starting and Idling Problems

    I checked my filter box this morning before leaving for work and everything seems tight except for 1 part and I’m unsure if there’s supposed to be something plugged into it. Please see photos below.

    Prado 1KZ-TE Starting and Idling Problems

    Ok scratch that. It was a fluke. Drove home and tried the same thing and unstable rough idle all over the place

    Prado 1KZ-TE Starting and Idling Problems

    On my way to my morning meeting I decided to do a little experiment. Going to the meeting venue involved a 40-60 mins drive through the highway and some traffic. I though I would try to drive with the transmission not on drive but on 3 and amazingly I had zero idling problems. As soon as I...

    Prado 1KZ-TE Starting and Idling Problems

    Haven’t had the chance to yet. I currently do not have the components necessary to run the test. Plus I had to cancel my trip to the auto shop due to work related reasons, so that’ll have to be rescheduled. What’s your opinion on my fuel pump? Is the SCV that part I encircled?

    Prado 1KZ-TE Starting and Idling Problems

    Also, here’s a photo of my fuel pump. The SCV part looks nothing like the ones I’ve seen on other photos. And a photo of my fuel filter (is there anything I can try to adjust there that would make a difference?)

    Prado 1KZ-TE Starting and Idling Problems

    I need to correct myself, it’s idling at 700rpm without the AC and around 800rpm with the AC. So I guess it’s fine. I took a video of how the rpm drops as I turn the wheel, I’ll upload as soon as I get the chance.

    I'm gonna try this today @TONYCY11, I'll report back if there's an improvement.

    Prado 1KZ-TE Starting and Idling Problems

    This seems like something that I should seriously look into. Upon observation, there is no change in idle speed when I switch the AC on. Idle is at 700 rpm upon starting the engine and remains at 700 even as I switch the AC on. Should the rpm go up to about 800?

    Prado 1KZ-TE Starting and Idling Problems

    Thanks for the sources @StarCruiser , that'll come handy once it's determined that it really is an SCV problem. I'm gonna have her fuel system diagnosed on Tuesday at a reputable auto centre, hopefully we can get to the source of the problem soon.

    Prado 1KZ-TE Starting and Idling Problems

    My 120 doesn't have a MAF sensor on the box, what it does have is an Air Inlet Temp Sensor located on the throttle side. I changed that to a new one and had some improvement but it didn't completely solve the problem.

    Prado 1KZ-TE Starting and Idling Problems

    @MarkW , my thoughts exactly. Actually, it idles fine even if I turn the steering wheel as long as the AC is off. I just don't know where to look so I can try to adjust the idling.

    Prado 1KZ-TE Starting and Idling Problems

    Hello StarCruiser! Great idea running from a can as an elimination process. I ought to check the intake pipes as well for any cracks. I do remember reading somewhere on here that though the SCV shows normal ohm readings, it can still be busted. So that's worth a shot. The only problem here in...

    Prado 1KZ-TE Starting and Idling Problems

    Hello TONYCY11, thanks for the reply! I totally forgot to mention that I did pull out the MAP Filter and sprayed it through and through with some carb cleaner. Wasn't dirty at all, carb cleaner came out clean even after shaking it in the filter. Checked for cracks as well and it looks to be in...
