Cadillac Deville Fuel Injector
Spotting Cadillac Deville Fuel Injector Problems
The luxurious Cadillac Deville can't be considered a rich man's car if it carries problematic fuel injectors. Having this problem means you have a vehicle with dirty and unmaintained internal parts. Other than that, the Deville also feels sluggish and awful every time you try to drive it. It's possible that you may end up with a car that doesn't run at all if you leave this problem unattended. That's why it's important that you spot the earliest signs of a problem as soon as possible. Here are some of the symptoms you can look for if you think your car has bad fuel injectors.
Starting a car requires an ignition, a cranking engine, and enough fuel compression. What's tricky about a starting symptom is that this doesn't directly point to faulty fuel injectors. Before you conclude that the injectors are bust, check the other parts first that also have a role in starting the car such as the fuel pump, filter, lines, electronics, and others. If these seem ok, you're a step close to isolating the problem to the fuel injectors.
If you manage to start the Deville but the ride is shaky, the engine misfires, or the engine's RPM is too inconsistent even when idling, these are signs of a shaky engine that's burning uneven amounts of fuel. The unevenness is caused by clogged injectors and low pressure in the combustion chamber. Other related symptoms include sudden stalls and hesitation.
Due to the unevenness in the fuel coming to the combustion chamber, you should also notice an overall decrease in your car's mileage. If your visits to the gas station are becoming more frequent, it's a good idea to check your Deville's fuel injectors.
Bad emission scores
An engine burning clean fuel shouldn't produce high levels of hydrocarbon (HC) and carbon monoxide (CO) emissions coming out of the exhaust. Too much of these are a sign of bad and dirty fuel being fed to the engine. The dirt may come from both the bad fuel you use for your Deville and from the dirty tips of unmaintained or old fuel injectors.
