Why does my Eddy 1406 carb keep popping?
I’ve checked the timing and that’s fine, I’ve even swapped carbs (from an Eddy 1406 to a Holley 3310-3), but the popping persists. So I’ve come to the conclusion that this must either be a compression issue or a cam issue, or something else I’m just not thinking of.

Why does my car idle but no check engine light?
This issue is normally caused by low fuel pressure or a faulty injector, but since you have just replaced the fuel pump, this may also be a sign of a failing idle air control (IAC) valve. This is a unit that is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected into the engine.

Why does my car sputter when I Turn on the engine?
The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
