Default 91 Civic/D16Z6 swap - at a certain point on my throttle, the car just cuts

So I have a 91 ef hatch with a d16z6 swap. Just put the swap in and now when I drive, at a certain point on my throttle the car just cuts as if i took my foot completely off the gas. Its not. So when i drive, unless im going up hill, i have to constantly be accelerating. I cant keep it at a certain speed because it cuts. Its a consistent spot that it cuts every time. Anyone know what this might be?? I was thinking throttle position sensor but im not sure. Just a guess. PLEASE HELP!! Thanks

Could be the TPS I suppose. Are you throwing any CEL codes? You are running OBD1 right? You didn't mismatch any wires, or not switch the distributor/ECU or something along those lines, did ya?

Other than the TPS, maybe check your ignition timing.
Don't forget to first disable the electronic advance by putting a jumper in the service connector.

Try switching the 2 outside wires on the tps plug. When I converted my first hatchback to obd-1 back in 2008 I had the same problem. I just switched the 2 wires and problem was fixed.

This is done when swapping from DPFI to MPFI. If you haven't done this, that's it for sure!

In the future, create a thread title that summarizes the tech problem. Title edited.

"NEED HELP ASAP!" is not adequate and may cause your thread to be closed.
