What Causes Sluggish Acceleration with a Check Engine Light?

The Problem

The vehicle owner noticed that the check engine light was on and the vehicle was sluggish to accelerate.

What We Found

The technician found that the #2 ignition coil had failed, three coil connectors were broken, and the spark plugs were fouled and incorrect for the vehicle.

The Fix

The team performed a tune-up, which included replacing the #2 ignition coil, the three broken coil connectors, and the incorrect spark plugs. They also conducted a basic inspection of related components and system functions to ensure everything was operating correctly.

The Result

After the repairs, the vehicle accelerated smoothly, and the check engine light was no longer illuminated.

Pro Tip

Sluggish acceleration can often be traced back to ignition coil issues. Replacing faulty coils and connectors promptly can prevent further engine performance problems and keep repair costs down.

Why Is My Engine Running Rough with the Check Engine Light On?

The Problem

The vehicle owner noticed the check engine light was on and the engine was running rough.

What We Found

The technician discovered that the #5 ignition coil and spark plugs were damaged due to water intrusion.

The Fix

The team performed a tune-up on the 6-cylinder engine, which included replacing the damaged ignition coil and spark plugs. This service was part of a scheduled maintenance that also involved a basic inspection of related components and systems.

The Result

After the repairs, the engine ran smoothly, and the check engine light was no longer illuminated.

Pro Tip

If your engine runs rough and the check engine light comes on, it could be due to ignition coil or spark plug issues. Addressing these problems early can prevent more costly engine repairs down the line.

FAQ

Tune Up in Lake Wales: questions answered

Answered by our licensed technicians serving Lake Wales.

What is included in a tune-up at your shops?

It depends on your vehicle, which is the honest answer rather than a dodge. We start from the factory maintenance schedule for your year and engine, add what testing shows, and give you the list before we touch anything. Two cars with the same mileage can need very different work.

Does my car need a tune-up if nothing feels wrong?

Scheduled maintenance is worth doing on time even when the car feels perfect, because filters and plugs wear gradually enough that you adapt without noticing. What you do not need is a package of parts added on top of that schedule. If nothing is due and nothing tests badly, we will tell you so.

Will a tune-up turn off my check engine light?

Not reliably, and we would not sell it to you that way. A lit check engine light means the computer stored a specific fault, and that fault deserves a diagnosis before anyone spends money on parts. Sometimes the fix is maintenance, and sometimes it is a repair that maintenance would never have touched.

How often should the engine air filter be replaced?

Your manual gives an interval, and dusty roads, grove work, and heavy pollen seasons can shorten it. It is easy to check visually, so we look every time the car is in and only recommend it when it is actually dirty.

Does every car need the throttle body cleaned?

No. It helps when carbon has built up enough to affect idle quality or throttle response, and it does nothing measurable when the throttle body is already clean. We look at it before recommending it, and that is a separate thing from cleaning your fuel injectors.
