Light Throttle Hesitation

[AllenRPS13]

as the title says... I cannot figure out what problems my KA S13 had... I already checked TPS sensor, Fuel Pressure, fuel pump, and I also cleaned the MAF... Any idea? :bash:

How's your tune up? Air filter, fuel filter, plugs, wires, ect.
If that is all good, check timing. Heck, check it anyway!!

plugs + vacuums...

how's going Allen?

[aznpoopy]

check engine mounts and mount bolting
check throttle plate for sticking
check throttle cable for proper tension

check the vacumm lines around the EGR, its typical that this one gets a fried hole in it which can lead to this kind of issue.
