What causes throttle delay?
When the filter is dirty, it can cause a delay in acceleration and throttle response because when the fuel attempts to pass through a filter that is clogged or dirty, it takes far longer than it would through a clean filter. Staying on top of your fuel filter cleanliness is one way to prevent poor throttle response.
Does the Civic Si have rev hang?
(Si)nus Infection What I don’t love about the Civic Si is a little issue called rev hang. It’s something that has plagued the turbocharged Si since its debut, and it truly bums me out. When I say rev hang, what I mean is that when you let off the throttle, it takes a long time for the engine speed to drop.

Aftermarket plug-and-play units are available for many cars and can improve throttle response. These are little computers that plug into your car, intercept the signal from the throttle and send a more aggressive one to the computer.
Why does my carburetor not work when I start the car?
There are numerous variables. Cold-starting and warm-up require a richer mixture, which is usually handled by a choke butterfly that limits the amount of air into the carburetor until the engine is at operating temperature. Acceleration, heavy loads and, in some cases, idling also require a richer mixture.
What happens when a carburetor is stuck in the cold position?
If this valve is stuck in the cold position, it will constantly direct hot exhaust gasses under the carburetor. This can cause hard starting when hot, as the fuel will have boiled out of the float bowl.
What are the symptoms of a carburetion problem?
Symptoms of a rich mixture can be misfiring and stalling at idle. Copious amounts of black smoke from the exhaust pipe are a tip-off to this condition.
What causes a carburetor to block the exhaust system?
If the needle of the vacuum gauge slowly sinks towards zero, there is a blockage of the exhaust system. Some engines, over a period of time, can have the heat passage under the carburetor become completely blocked.
