Drivability issues.
I've been having some drivability issues for the past couple weeks. It seems to have started since I soaked the intake in water way back in March. After all that happened, I replaced the filter, cleaned the MAF, changed fuel pump to Walbro 255 and changed O2 sensors. It seemed to be better after all that.
Car is 24x swapped, 223/231 cam, manual.
Basically, the car will go lean when the gas pedal is pushed after not being pressed, but only for a split second and it'll go back to normal and deliver power. No codes other than EVAP.
Is this just a 24x thing, or a tune related issue? Still on my mail order tune from Moe.
Thoughts?

How does the voltage look at the TPS sensor, rotating the blades from closed to WOT? Does the voltage increase smoothly, with no dropouts or spikes?
Do you have a good, tight, no-leak connection from the MAF sensor to the throttle body..... no loose clamps, no tears in the rubber, rubber fully over the throttle flange, particularly at the bottom?SOLD - GONE TO A (VERY) GOOD HOME ! - 94 Formula A3+1: 381ci forged stroker - Callies Stealth, Oliver 5.85 billet rods, BME nitrous pistons / CNC LT4 heads / CC solid roller / TH400+GearVendors OD / 4.11 Strange 12-bolt / 300-shot N2O / Spohn Suspension / roll bar / MoTeC M48 Pro engine management system /a few other odds 'n ends.

Did you clean the IAC ?
