I removed the EGR and EGR tube when I went to the new mini header. I’ve also removed all the drive belts and test drove it and it’s still present.if you have egr, check that out. make sure it's plumbed properly
dead throttle says tps or maf to me.I do. I wonder if watching the rear O2 sensor would show anything. It sounds like it’s before it. I also wonder if it’s why I have a random dead throttle when taking off sometimes.
It’s a drop in MAF. I’ve tried a different Toyota TPS and the same issue. It’s only in first gear when it drops off. It acts like it stalls and then takes offdead throttle says tps or maf to me.
without digging back, do you have the drop in maf or module piece?
It looks solid and AA has been around for a long time. I would’ve gone with their adapter but I bought my MC08 back in 2016 and it’s been sitting in the shelf since then waiting for me to use itI have not but I probably would. I thought about getting one when they have been on sale just to have a spare. I have been running their TX2 adapter for a long time. Not as pretty as a Marlin or TG but it works.
I thought I had a drop in maf but now I’m questing it. When I look up the part number it shows the entire assembly. I have the 5 wire MAF and not the 3 wire one. Do you think a later model on will be interchangeable? I’ve been looking for threads on it and keep finding for the 3.4.dead throttle says tps or maf to me.

never heard of that before. cool deal.I cleaned the MAF and it seemed to help. I’ll keep an eye on it and if needed I’ll order a new one from Toyota. I also picked up another t case. It’s a forward shift but it was only $150 for it. I’ll convert it and the other forward shift I have to top shifts and build my duals.
I was talking with a mechanic friend about it and he suggested I use chassis ears to help find the exhaust leak I’ve been fighting. It only happens under load on a road. With the chassis ears it took less than 30 minutes to find it. I hooked up all 6 leads around the exhaust and had a control one in the middle on the transmission crossmember. In the second photo there’s a lead with a blue band on it, when listening to that channel it’s the loudest. It’s definitely coming from where the manifold connects to the down pipe on that side.
At this point I’m going to remove the clamp that holds it to the transmission to see if that’s applying a weird load under torque allowing it to happen. I’ll also try to tighten it more.
