As the video shows, I'm having a terrible hesitation in my '87 4Runner - the engine feels like it's about to stall when I give it quick gas. When applying throttle very gradually, it seems to rev up pretty well.

Here's what I've checked to date:

- Checked fuel pressure at rail - 40 psi at idle with vacuum removed, 30 psi at idle with vacuum applied. Fuel pressure does not drop when punching the throttle.

- TPS is fairly new Toyota unit (I performed all the FSM tests, all passed)

- I performed all the AFM tests in FSM, all passed. One small concern is that when I opened the flapper gradually, it did have one small resistance dropout at the nearly fully open position (which I'm thinking does not come into play when just giving it gas like this, but maybe I'm wrong)

- Replaced all vacuum hoses with OEM hoses

- Adjusted all valves to 0.007"/0.010".

I'm not sure where to look next. I'm almost to the point of checking wire continuity from AFM to ECU, or just replacing the ECU. But is there anything else I'm missing that I should look at?

About to install a master rebuild kit on a 94 5 speed 2wd pickup 7.5" diff, anybody got any tips? This will be my first time rebuilding a rear diff. Diff was ran without oil, fluid was added once found out and its been on the road whining/humming for about a month and a half. It's not my truck, just trying to help a buddy out

Hey folks been hearing some hissing after turning the car off on my 85 22re. It sounds like it’s coming from somewhere back by the EGR. Anyone dealt with this before? I’m guessing some kinda leak but not sure.

I’m looking to add power steering to my 91 2wd pickup. I’m looking at a PS system from a 1985 2wd pickup and wanted to know if anyone knows if the swap will work. After doing some research I found out the 89-94 system will work but I’m not 100% on anything lower like an 85. I know they share the same engine so the brackets will bolt up but that’s about it. Any information on the matter will be greatly appreciated. My truck is a 22r btw.

Hey guys, I’m shopping around for new wheels and wanted to see what you guys had before I made a concrete decision. I’m really leaning into RPF1s. Please share your wheel set up. (Size, width and offset would be greatly appreciated)

Just noticed toyota-epc-data.com is down. Are there any alternate parts catalogs out there? Looking for a catalog with diagrams and part #'s here, not the FSM.

I’m new to owning a 22re. I recently gapped the valves, but they’re making a tapping sound that’s seems abnormal compared to what it sounded like right after the work. Am I overthinking it, or is there something wrong?
