Injector problems are not very common on newer cars, and because of this, you want to check out the other possible causes first, but it is absolutely worth checking. [links]
So, when you suspect that your engine is misfiring, where should you start looking for the problem? more
The second most common cause of a misfire is bad spark plugs. The spark plugs fire up your cylinders, and they can get worn over time. Spark plugs are often very cheap and, in most cases, easy to replace. here
The car engine is most sensitive for small air-fuel mixture problems at idle, so this is probably one of the first places you notice misfires.
Misfires are one of the most common problems when it comes to modern gas engines.
Well, from my experience of over ten years with car repairs, here are the most common causes of engine misfires: more

Many of these extended pumps are machined from billet aluminum, and some use gerotor gears instead of common spur gears. Gerotor gears deliver a smoother supply of oil pressure without the pulsing that is characteristic of spur gear pumps, and the gerotor design greatly reduces the chance of cavitation at high engine speeds. Many dry sump oil pumps also feature gerotor pressure sections for the same reasons. more
So why does everyone seem to think that all high-performance engines need a high-pressure, high-volume oil pump? It used to be standard practice to open up the main and rod bearing clearances in a high-performance Rat motor beyond the stock .0025- to .003-inch clearance, and to use a high-viscosity oil the belief that it gives more protection to the crank. Such practices increase the amount of internal hemorrhaging (leakage) in the lubrication system, and do indeed require an increase in oil pump volume.
Choose a pan that fits your car with as much capacity as possible to keep the oil cool. The number-one priority of your oiling system should be to keep the engine supplied with oil, and big boxy pans make it harder to control oil slosh during braking and cornering. Consult with the oil pan manufacturer for application guidance; they’d rather sell you the pan you’ll be happy with than some exotic pan that’s wrong for your street car. more
Today, we can enjoy the benefits of better lubricants, especially with synthetic oils, and tighter bearing clearances actually provide better bearing life because the hydrodynamic wedge of oil, which supports the crankshaft when the engine is running, is stronger when the clearance is only .0025 to .003 inch. The general rule for high-performance engine oil pressure is 10 pounds per square inch for every 1,000 rpm.
Install a high flow air filter and cold air induction intake. A restrictive or clogged air filter will force the engine to work harder to breathe, which makes it less efficient. A cold air induction setup will feed the engine cooler and more oxygen-dense air. These modifications will help to generate more horsepower without adversely affecting fuel efficiency, which will ultimately increase net mileage. [links]
Use a set of long-tube headers (exhaust manifolds) and an aftermarket exhaust system. That extra air going into your engine needs to get out somehow; installing a full aftermarket exhaust system like this is always good for more fuel economy, especially when combined with a freer-flowing intake. This modification won't be cheap or easy to install, but will eventually pay for itself if you do a lot of towing or drive a lot of miles.
Switch to a lightweight synthetic oil. Although Chevrolet doesn't specifically recommend it for this engine, the extreme slipperiness of a full synthetic will allow you to run a thinner weight oil without worrying about undue engine wear. Thinner oil drags less on internal engine parts, helping the engine to spin more freely and run more efficiently. After all, every horsepower lost to such "parasitic drag" is one less that won't be helping your truck move down the road. here
Also known as the Vortec 7400 (7.4L, Regular Production Option designation L29), Chevrolet's Vortec 454 was a modern-day evolution of the company's most legendary big block. The 7400 was essentially the same big block 454 that carried Chevy through the muscle car years, but a hydraulic roller camshaft and revised cylinder heads helped to make it far more efficient than the old LS6 could ever dream of being. Even so, this engine was built primarily to provide huge towing power for CAFE-standard exempt vehicles, so there remains some room for improvement. [links]
