Throttle body can causes vehicle to lose power

Throttle body can causes vehicle to lose power

Q. Last winter and the winter before when it was below freezing, my 2006 Chevrolet HHR displayed a "reduced engine power" message, and I couldn't go over about 5 miles per hour. This past winter when I was driving my Bichon to the vet, I had to pull over and stop the car. After a short time, I restarted the engine and had power back. Thank heavens. I didn't want my little dog and me to freeze to death. I took the car to the Chevy dealer with the Check Engine light on. They said I needed a throttle body assembly. Condensation was found in throttle body assembly and PCV system, with a need to remove and clean the intake ports and valve cover. Estimate cost, $1,154.36. They must have done something because the Check Engine warning light went out. I'm a senior woman with a really tight budget and no room for this expense. My question is do I really need it? There's no problems in the warm and mild weather. It appears only the intense cold affects the e ... read more

Brake repairs should be done before winter

Brake repairs should be done before winter

Almost all of the leaves are gone and that means winter, unfortunately, is just around the corner. We still have some time before we need to get serious about prepping the car for winter. So today I want to talk about brakes. Several people have asked me lately about brake concerns. Several folks have asked what could be the reason for a squeal sound when they put a light touch on their brake pedal. The other complaint was a pulsation in the pedal when stopping. The brake squeal could mean they are getting close to the end of the life of their brake pads. Most brake pads have a thin metal tab that starts to touch the brake rotor when the pads wear down. When brake pads near the end of their life, the tab touches the rotor and it creates a high-pitched squeal when rolling at slow speeds or upon light pedal pressure. This noise usually goes away when heavily braking. If you are experiencing this, it would be a good idea to have the brakes checked because the pads may be wearing out ... read more

Dual-clutch automatic transmission causes 4 to 5 second hesitation

Dual-clutch automatic transmission causes 4 to 5 second hesitation

Q. We have an ongoing problem with our 2015 VW Passat with a 1.8-liter, turbocharged TSI four-cylinder engine and 6,400 miles. The problem is a 4- to 5-second hesitation with the engine in drive after a stop light while making a left turn. This hesitation is also encountered after we back out of the garage in the morning. After shifting into drive to move forward, the hesitation is more pronounced. After driving forward about one block, while making a left turn onto another street, this hesitation is no longer as predominant. However, it can happen even after the engine is warmed up or while moving forward after a stop light. It seems like the engine loses power for the few seconds, but if you press down further on the gas pedal, the car will lurch forward. We have been to the dealer and they said this is normal. My wife feels very unsafe driving this car and has become very careful not to enter into traffic because of this problem. The dealer suggested using brand-name premium gaso ... read more

Power Stroke diesel engines have specific maintenance needs

Power Stroke diesel engines have specific maintenance needs

Q. I recently purchased a 2010 Ford F250 with a diesel engine in it. Having never owned a diesel before, what am I looking at for maintenance and how often should it be performed?   A. Congrats on your new truck, I hope it serves you well for a long time and with the proper maintenance it will. This is by no means an exhaustive list, but if you do these basic things it will go a long way to maintain your diesel engine. • Change the oil every 3,500 to 5,000 miles depending on your driving habits. There are a lot of components in a diesel engine that the oil controls, so you definitely don't want the oil thinned out by fuel from the regeneration system present in your truck. • Check the coolant every 15,000 miles for acid content and general quality. You can do this with a dip-strip. • Change the coolant every 30,000 miles. This is very important on a diesel engine because the coolant tends to get acidic and will damage internal engine components. • Cha ... read more
