The System Does Not Start Or Run Poorly
Many people have complained that they have spent hours getting the system to work correctly, only to end up with a car that runs poorly.
Sometimes it just cranks without starting after you must have checked some of the parts.
It could be due to several factors, including an insufficient power supply, dirty injectors, or low fuel pressure.
Another common issue is that the system isn’t getting enough air. It can be caused by a dirty air filter, a leak in the intake system, or a problem with the carburetor.
The problem can lead to poor performance and decreased fuel economy and can even cause damage to the engine. It is a common challenge for novice users.
The System Is Susceptible To Variations In Height And Temperature
The system starts and runs fine when cold, but it runs terrible when it reaches the average operating temperature. It will backfire, miss, and run rough.
You may have had the fuel pressure checked, and it is OK.
You may have also replaced the plugs, wires, cap, and rotor and even replaced the carburetor with a new one, yet the problem persists.
It can lead to the engine not running at all. People have reported that the system has stopped working suddenly.
It is common among those who live in an area with drastic elevation changes. It is also seen among those who often drive in and out in high lands.
One of the main problems with the Edelbrock system is that it is not compatible with some cars.
It is adjudged as compatible with a wide range of vehicles, making it an excellent choice for those looking for an upgrade and the novice in automotive mechanics.
Yet a few vehicles are incompatible with it. Before purchasing this system, you should ensure that your vehicle’s engine is compatible.
Installation Can Be Difficult
Especially for beginners if you are not familiar with how to install it.
If you do not follow the installation instructions carefully, you may experience problems such as poor performance and engine stalling.
The installation instructions could appear vague without guidance about which parts to use.
Even when you try following the instructions, you may get stuck along the line.
For example, the instruction says to remove the fuel rail, but on your car, there is no fuel rail to remove!
Finding the right parts may be a problem because they are not common.
For example, the instruction says to use a 3/8 inch Allen wrench, but the only Allen wrench available is 1/2 inch.
Poor Customer Service
Arguably, Edelbrock has been accused of providing bad customer service. Their response may not be constructive.
They could keep referring you to read the instructions, which you must have read without much guidance from it.
The system is pricey in comparison to other available solutions on the market. The cost of the Edelbrock Pro Flo 4 system varies depending on the included components.
Generally speaking, the cost is far above $1,000.
Poor Idle Quality
It can be caused by several factors, including incorrect calibration, dirty injectors, and leaking fuel pressure.
Running Too Rich Or Too Lean
Some things can cause your Edelbrock Pro Flo 4 to run rich or lean. A filthy air filter is one of the most prevalent issues.
If your air filter is clogged, it will prevent your engine from getting enough air.
It will cause your engine to run rich, as it will not be able to burn all of the fuel that is being injected into the cylinders.
Another typical issue is a fuel line leak. A leak in the fuel line can cause your engine to run lean, as it will not be able to get enough fuel.
If you suspect your engine is running rich, it might also be because the jets in the carburetor are too large.
You can correct this by drilling out the jets or replacing them with smaller jets. If the engine is running lean, you might need to replace the needle.
Poor Throttle Response
You will need to ensure that your car has an electronic throttle body and that it is not a return-style fuel system.
