What kind of test will enable me to know what is wrong with my engine? This truck has a hard time picking up speed up even small hills. It also stutters between 40 - 50 mph, then picks up the speed a

I am driving on the access road of our local freeway. When it is going uphill, my Montero does not want to go up at an even pace, kinda just lags along. Also when I am entering the freeway or trying to pick up speed just going down the road, my Montero stutters between 40 - 50 MPH. After 50, it will pick up the speed quite well. Any ideas here?.

SOURCE: i have changed my battery 3 times and it keeps going dead

Did they test the output only, 13.5 to 14v if it was all that was tested there are two other possibilitys that the alternator needs testing for Voltage regulation which will fry a battery (over charge and cells collapse)or the diodes have failed which will flatten a battery overnight.

I have the same problem, you need to change de oil transmission or try an additive for aut. trans that resolve the problem for a while, but is almost most better changing de oil.

SOURCE: Mitsubishi Outlander 2003 Service Engine Soon

You'll need to know why the service engine light comes on, they can check this by using a OBD II diagnostic tool to find the trouble code stored in the pcm, ask them to run a check on it, or you can take it to a mechanic before you buy it to have them check over the vehicle for any minor or major problems.

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.

No pick up

Have you changed the fuel filter lately. Sounds like you have a fuel restriction. You could have a clogged catalytic converter. When the car is in park rev the engine and listen. Does it sound like the exhaust is having a hard time getting out? Hope this helps.
