I'll try to explain my problem.

While driving on the highway at a steady speed. Sometimes it feels like the engine "dies" for a split second. I looked at my Wideband and the reading goes from ~14.7 to 17-18 for a split second.

I never had that problem at WOT.

What could it be? Injectors, fuel pump, fuel pressure regulator, fuel filter?

I'm running a stock ecu with a SMC+, RC550cc injectors, Walbro 255lph, stock Fuel pressure regular and fuel rail.

Thanks for you help.

It's more than likely a "dry spot". Get it street tuned and you'll be good to go.

 

What would cause it to only do it when I'm cruising at constant speed? It never does it when I'm accelerating.

I think its strange becasue the car ran fine for 3 years. I didnt change anything in the tune or changed any parts of my setup.

 

so it just started happening then?

 

It started this spring yes.
