Have you tested the TPS? Especially with the auto tranny being stupid at the same time thats where i would look next.

yup my bet is the timing belt has skipped a tooth or two. as toyotech said, pull the covers and check, and mostly likely just replace it while your at it.

I think he means that if he takes off his intake plenum he will have better access to the plugs, so which gaskets would he need if he did that. OP, it is definitely possible to change the plugs without removing the intake plenum, just a bit more tricky. If you do decide to take off the intake...

if you've got a 3.0, then you dont have a mass air flow, you have a vane air flow meter, and so it is all one big "sensor", and it doesnt get any smaller than it already is. You can move it around and position it to better fit a cone filter if you want, but don't try and take it apart. If you...

You may have already looked into this, but check out the bracket that holds your clutch pedal in place and make sure its not cracked and warping when you engage the clutch. When I bought my 4runner, the PO told me I had to press the clutch engage button to start the truck. It turns out the...

I recently did this and it worked great. Its only be a couple thousand km's but its still holding great no leaks. I used injector hose and injector clamps (both of which are designed for efi fuel lines). If you want pictures let me know. Cheers,

its hard to tell. Really the only issue that was present while it was plugged in was really poor mileage and throttle response, and the idling wouldn't stay at 800 rpm. It ran fine though, no rough idle or surging while driving. The throttle response seems a little better, and the idle stays...

well I drove it around for the day unplugged and no cel ... I figured that should have triggered it

Hey guys, So I am trying to pin down the reason for my 4runner's horrible gas mileage, and am starting to think it has something to do with the TPS, but I am looking for some advice on my situation. Lately I have been noticing that every once and a while my idle will drop from 800 rpm to...

Yup that one is definitely on my list of things to do. The only problem is that I know that I will basically need to replace everything past the O2 sensor as soon as I want to check the cat, so I have been holding off until I have the money to do so. Thanks for the tip though

I actually have seen that thread a couple times while google searching for answers haha, but thanks anyway for letting me know about it :)

I think one of my problems may be the fan clutch. If I am current, the way to test it is while the engine is off and cold, try and spin the fan. If it is working properly, there will be minimal resistance, and if it is not working well then it will not spin freely? Can someone confirm that for...

UPDATED: -Check Compression -Check Timing -Replace Fuel Filter -Check AFM (All pins within spec when resting. Will take the afm out on the weekend so I can move the vane and check the resistances when the vane is open) -Check Fuel pressure -Check Fuel Injectors to see if they are leaking -Check...

Bad fan clutch is a great thing to check. I gotta wait for the truck to cool down and then i will go check out how much resistance the clutch is giving. Thanks :)
