My '99 Dodge surges when I go out to start it. I usually have to cycle the key at least three times before I try to crank the motor before it will start at all. It does this every time, however, sometime it takes more attempts than others. It has taken me up to 5 minutes to get it started before. It always starts eventually, and when it does, it runs great. No problems with power at all. When it's surging, the pedal is completely dead. It will not move or do anything other than surge. After a fe

I just tried a trick that one of your solution providers had given me. I was able to trouble shoot the blower motor troubles. The assistant told me to rap on the blower motor that was under and beneath the glove box. although the solution didn't work, I realized that it probably was not the motor but possibly the fuse. I looked in the fuse panel and found that both of the 15amp fuses were blown. I just replaced the fuses and the blower works again. My question is what would cause a surge to make

Had the engine replaced on my 96 ram 4x4(truck is a 5.9L with auto trans). Was replaced with a low mileage used motor, according to the guy who installed it. (Of course he's not around anymore) Ever since, the truck has been acting up. The motor runs fine, but when I floor the gas pedal (ex. if passing someone) the a/c immediately shifts from blowing out of the front vents to the windshield defroster vents. The transmission also acts as though it's slipping and surging, and I have gone through 3

Kia Optima I just replaved my timing belt, oil pump belt, crank senser, map senser, R & R senser. The timing belt was not broke but did have a few missing teeth. It will start and run just fine on a cold motor. After the motor warms up it has a rough idle, low idle, and will eventually die without keeping the idle up with my foot on the gas pedal. It will surge on highway speeds, most climbing hills. It also has developed a vibration while accelerating. Jump before it shifts into a higher gear.


Is the car flashing any codes. I would look for fuel issues possibly fuel filter, injectors etc. Because these items are easier to check. Otherwise it sounds as if the timing is off on the car. If the Hydraulic tensioner is not replaced this coul ... 2004 Kia Optima
