Report A Problem

Engine will not idle after a battery change especially when air conditioner is on. Read this is common problem. The computer that controls the engine idle loses it's memory and no longer remembers how to idle. Fix by driving the car between 5 and 10 miles. This puts the lost data back into the computer ECU and now it idles just like it did prior to the battery problem.

The intake manifold makes rattling sounds when you depress the gas pedal.

There is a manufacturing defect in the baffle that is loose inside of the intake manifold.

The fix is to replace the intake manifold.

The proper repair for a leaking Steering Rack & Pinion is replacement with a new unit.

Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

 

The valve cover gaskets have a tendency to leak oil, especially the one near the firewall.

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

Cars equipped with an automatic transmission might experience a hesitation when accelerating. Revised software for the on board computer is available which may correct this problem. Software revisions are commonly most helpful on newer vehicles. once the mileage builds up a worn component could cause similar problems. Whenever major transmission work in performed, the transmission software should be updated as necessary.

The power steering pump and power steering hoses tend to develop leaks, particularly in the V6 models.

One or more motor mounts may wear out on cars with high mileage. This will put extra stress on the other mounts, and the faulty mount(s) should be replaced.
