Hi all,

I recently completed the conversion and have a problem. The car starts ok and runs but it surges and hesitates especially when the car is cold. It gets a little better when warmed up. At idle it also varies the revs up and down.
I used the full MPI loom including the ECU and associated wiring/sensors. I also used the MPI dizzy.Any ideas why the car is doing this and what should I be looking for? Any help would be greatly appreciated.

Forgot to add that the car is an EbII with a four speed auto. And before you ask yes, I used a MPI set up from a 4 speed auto car.

Did you use a MPFI fuel pump?

Yes.
