An older vehicle with an expensive repair diagnosis is a good time to consider the more common causes first.

Once restarted after the 40-plus minutes of waiting, it runs just fine. This problem doesn't happen in the winter, only on hot summer days, and every once in a while it idles roughly, but not often. It has been extremely frustrating to have to always wait awhile after driving it somewhere before I can drive it again.

QI own a rear-wheel-drive 1999 Jeep Grand Cherokee with the 4-liter engine. I recently had both rear axle seals and bearings replaced. At the same time I had the mechanic check U-joints, shocks, etc. The noise from the failing bearings is gone, but now I have a loud "howl" that gets louder the more I accelerate. If I take my foot off the accelerator, the sound is gone. As soon as I accelerate, the sound returns. It is barely noticeable at speeds less than 35 mph, but the howl gets increasingly louder as the speed increases.

A safety system might be frustrating, but it's mandated.

Q I recently took my '02 Chrysler minivan in for 100,000-mile service and was told that one of the spark plugs would not come out of the cylinder head. The shop tried, but it would only come out so far. Rather than force the plug out, they just screwed it back in place and replaced the other five spark plugs. The van is running fine but what happens if the old spark plug goes bad? Is it OK to do nothing, or should I pursue having it replaced?

QI am writing to you about my wife's 1987 Mazda RX-7 with 154,000 miles on it. The engine still runs perfectly, but I am concerned because it does not use any oil whatsoever between 3,000-mile oil changes. I am concerned that the "metering oil pump" is not working properly. This is the pump that lubricates the rotor apex seals.

His wife could not get the transmission shifted out of park on her 2008 Chevy Impala. Now they never park the car with the front end up. But why?

My daughter asked me why all the lights -- headlights, tail lights and dash lights -- pulsate at about two pulses per second on her 1997 Cavalier. Sometimes it's very noticeable, other times not so much. About the only time they don't pulsate is when it's at a stop with the foot on the brake. Any thoughts on how to fix this?
