It is not unusual for engine vacuum hoses or sensor electrical connectors to cause driveability concerns and/or the Check Engine Light to illuminate.
Fuel injectors or their o-rings may leak fuel causing the engine to burn too much fuel.
Various driveability concerns can be caused by deposits on the back of the intake valves. Fuel injector cleaner has shown reasonable results cleaning light deposits.
A dirty throttle body can cause a low idle condition resulting in a stalling condition.
Some engines may experience a cold engine knock that lasts for three to five minutes after start-up, which is often misdiagnosed as a valve lifter noise. This noise is commonly not an indication of a failure and should not be a reliability or durability concern.
Excessive oil consumption—defined as more than one quart per 1,000 miles (on vehicles with less than 50,000 miles) or more than one quart per 750 miles (on vehicles with more than 50,000 miles)—is common. Replacing the valve guides with an updated version should fix the problem.
A broken rear torsion bar can cause an abnormal noise over bumps. The torsion bar is part of the rear trailing arm, which must be replaced to correct this issue.
