SOURCE: 2002 kia spectra has hard time picking up speed

I had the same problem. I changed my fuel filter too.Your catalytic converter is clogged. I could put the pedal to the floor board and couldnt hardly pick up any speed. I could hardly make up a hill on the highway. Take it to a kia dealership and they will, they should replace it for free, they did mine and I didnt have a warranty. I think there is a warranty on that specific part. That's what it is though.

SOURCE: Driving on freeway, gas pedal depressed half or

This is a very minor timing problem.
Either the spark is too far advanced, or too far retarded.
If you've a set of 'feeler gauges', you will know what to do now.
Alternatively, take it to a 'Trusted' garage.
I say 'Trusted' because, unfortunately, there are too many 'garagist's' (if you like,) that are quite happy to take your hard earned green, in exchange for less than nothing.

There ya go, and please, don't forget to rate.

1983 s10 blazer low rough idle and trys to die when starting have to give it a little gas and put it into drive real quick then when slowing down keep foot on gas pedal as i also slow down with break pedal


Could be several things, a vac leak, dirty throttle body, or faulty idle air control valve.
The computer controls idle speed by how much air enters the throttle body thru the valve.
Usually a vac leak would speed up the engine unless it is causing the rough idle.

When slowing down the transmission feels as if it is jerking in to the next gear.


after checking fluid level is correct, try this, to see if it improves...
into drive,let car accelerate without any gas(do not touch pedal)to max speed (about 30/35mph).stop,then with 1/3rd gas pedal,accelerate to max speed(do not move foot)stop,then foot hard to floor,upto about 60mph,then stop.then only using a max of 1/3rd gas pedal,drive for about 15miles.you have just reset the drivetrain computer setings....the car is fitted with a computer controlled fuzzy logic gearbox,it will try to make you drive as eco as poss,but if used harshly the gearchange can be harsh up and down.....
if driven gently 4th will engage at 43 mph,with a slight clunk.

2002 GRAND AM SE CUTTING OUT GOING DOWN HIWAY AND THE rpm'S GOES UP FELLS LIKE SOMETHING SLIPPING


If the rpm's go up and the car feels like it is slowing a little even though you haven't moved the gas pedal a bit with your foot then you may certainly have a transmission that is slipping. Usually a slipping transmission is most noticable at first when speeding up to merge into traffic or after the transmission is fully warmed up. If you feel it is slipping you should have it checked out as soon as possible to prevent further damage and the risk of being stranded on the road.

I have a 2008 Honda CRV and for the life of me I cannot engage the Cruise control- I press the Cruise Button on the right of the steer wheel and nothing happens - nothing Help anyone ? Tks Nancy


The cruise-controls have 2-buttons that must be activated before it gets the car going when you remove your foot off the gas-pedal.
The cruise button is essentailly a switch that turns 'on' the cruise servo-motor that tells the sytems that you wants to use it, so it gets ready.
There are other three switches on the right-side of the steering wheel namely: resume accel; cancel; set decel.
To get your car to cruise: you must steady your speed and foot on the gas-pedal. You cannot just press the switches and expect the car to cruise. It takes about two-to-three seconds for the system to respond to a set cruising speed.
How to do it: accelerate to a speed of about 30-mph. Press the 'cruise' button on the dash first. Next you press 'set decel' button. This will turn 'on' the cruise control light on the instrument panel. Then wait a second or three and you would feel the cruise engagement. Any touch on the brake pedal will slow down the car and turns the cruise off. The 'cancel' button turns off the cruise light on the instrument panel.
If you hit the brake-pedal at any time for any reason, and you would like to continue cruising again, simply press the 'resume accel' button.
The cruise system works in conjunction with the braking system of the car. So all major parts of the braking system must be in good condition, otherwise the cruise system could shut off itself.
