Perhaps a fuel issue?

It could be your throttle positioning sensor because they can cause cars to do that. You should also check the MAF sensor and for vacuum leaks.

Check the voltages on the MAF sensor. What's the reading at snap throttle?

I notice your CEL is flashing. Check what code you are having.

Ok it looks like you got code 14 which is IGF.

So run a seperate wire from the ignitor to the ecu maybe that wire it broken somewhere in the loom or pin is loose at the ECU.

IGF wire on the ignitor is on the 4 pin connector and pin #3 first pin on the bottom right.

Ecu will do that also..

Sorry took awhile to get back. Just busy...but yes that's what I was thinking too cause when I unplug the tps it'll idle okay and I could rev past 2k and it'll be fine. I it. So than I try using the tps from the 2jzge motor not sure if it'll work but I did anyway and than it went back to where I can't rev past 2k so could it be my tps sensor?

Code 14 is ignitor signal. Check if you got a broken wire from the ignitor to the pcm. If not, you got a bad ignitor

Do you happen to have any pic that I could see? It'll be very helpful or
Know an forum that shows how to do it?
