What Causes a Car to Run Rough Despite Exhaust Repair?

The Problem

The vehicle owner reported that the check engine light was on and the car was running rough, despite a previous diagnosis of an exhaust leak.

What We Found

The technician found that in addition to the exhaust issue, there were multiple underlying problems including an oil leak and a faulty ABS wheel speed sensor.

The Fix

The team performed a thorough tune-up of the 4-cylinder engine, replaced the engine oil cooler gasket to fix the oil leak, and replaced the exhaust crossover pipe. Additionally, they addressed the ABS issue by replacing the right front wheel speed sensor and performed a final road test.

The Result

The vehicle ran smoothly after the repairs, with the check engine light off and improved overall performance.

Pro Tip

If your car is running rough even after an exhaust repair, consider a comprehensive tune-up. It might reveal other issues like oil leaks or sensor problems that could be contributing to the rough performance.

FAQ

Tune Up in Sebring: questions answered

Answered by our licensed technicians serving Sebring.

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.
