Why Is My Dashboard Lighting Up and Car in Limp Mode?

What the customer reported

The vehicle owner reported that the dashboard was lit up like a Christmas tree and the car was going into limp mode.

What we found and did

The technician found multiple cylinder misfires present, which required further investigation to determine if fuel injectors might be needed. The team performed a tune-up on the 6-cylinder engine, which included basic inspection and replacement of necessary materials. They also addressed the TPMS issue by installing two new sensors and replaced the air bag clockspring to resolve the air bag light concern.

Result

After the service, the dashboard lights were cleared, and the vehicle no longer entered limp mode.

Pro Tip

Dash lights that illuminate suddenly often indicate multiple issues. Addressing them promptly can prevent more serious problems and costly repairs down the road.

Check Engine Light Flashing and Engine Running Rough

What the customer reported

The vehicle owner reported that the check engine light flashes and the engine runs rough.

What we found and did

The technician found plugs fouled from oil saturation from a leaking valve cover gasket, a broken coil connector that damaged a coil, and heavy carbon build up in the fuel system. At our Haines City shop, the team performed a tune up for the 4 cylinder engine that included a coil pack, coil connector and induction service with valve cover gaskets. The team also did an oil service with MOA additive since the incoming oil level was low and dark, and replaced the missing brake reservoir cap.

FAQ

Tune Up in Haines City: questions answered

Answered by our licensed technicians serving Haines City.

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.
