Ok all, I really need someones help here. This is the Situation....

I have everything wired up in my Supra correctly using the Plug and Play harness. Im wiring a SAFC into it correctly and when I start the car up, It Idles like a Dream. Problem is that when I start to give it gas It start to Sputter really bad (Doesnt Die) It doesnt matter weather Im sitting Idle and hold it at 1500rpms or Im trying to drive it down the road, It Sputters like crazy. Let off the Gas and it Idles Perfect again.

Ive Hardwired it in also and It does the Exact same thing. Ive tried it without the SAFC and still the same results. Only Difference I think is that I have a 550 Chip installed and Im still on the Stock 440s.

Would that make a Difference. Dip Switches are set correctly.

1. Down
2. Up
3. Down
4. Up

Would someone Please help me resolve this Issue. Does this sound like a Pressure Sensor Issue and if so, How do you check the Sensor to make sure its Operating Properly.

Thanks
Robert

Either put the right injectors in it, or a ROM meant for the stock injectors.
Your off by a good 25% on fuel delivery!
Engines won't run with that much of an error in fuel delivery.

If you need a 440 ROM, let me know.
