Has anyone on here built a fuel heater? This is going to be my next mod.

The temperature in the last few days has drop off into the low 60's F.

I have been doing some testing and have noticed that my FE has drop off a ton due to the cold temps.

I'm running in open loop all the time so my IAT, ECT sensors have adjustable tables and I have made changes to get back to my desired A/F ratio around 19:1 but the engine is surging at this ratio where it did'nt when the temps were in the 80's F.

My thoughts are its a "atomization fuel" problem?
