Just had a new stainless system installed and I took it to the shop I got it from because it was cutting out and he says it might need a fuel regulator because it's flooding?

Just want some advice really?

Cheers lewis

If you're running injection still then the bloke is talking out of his arse.

Give us some more details about your setup and the cutting out. Any air leaks in the exhaust near the lambda sensor?

you I agree injecton and exhaust been stainless will have no change now if the sensor has got damaged be heat or weld it could cause it try getting it plugged in
