2JZGTE Stumble when throttle open
Hey guys...been awhile. Had some personal stuff come up and now I can get back to playing with the car. I have posted a video so you guys can see/hear what is happening.
My thoughts:
1. Fuel issue? This has the stock USDM GTE injectors and a walbro fuel pump with 12v bypass. I have not checked the pressure, if I do that I will redo all the hoses as the stock system is a PITA to get an inline into.
2. O2 issue. I am thinking highly unlikley since this is just at start up. I was having this with no code and no sensor connected. I connected the sensor and now throwing a code. Going to go back and look at the wiring.
3. Just another datapoint I am having a cold start issue. I am thinking it is in the wiring. If I spray starting fluid in it will start fine as you see/hear in the video. Without it I will just crank and crank.
yes I have new plugs, new gas, getting fuel. If I just let it idle without opening the throttle it will idle just fine.
Thanks guys. Its been a long time and I just want to finish this up.
