When i am accelerating, pushing the gas pedal the rpms go down significantly then riser significantly. now there is a deep rumble or vibration if i go above 50 and the check engine light is on. i live in flat terrain with occasional hills but drive mostly highways.
I'm not sure if it is in the motor or transmission of my suv. what happens is when i am driving on the highway i push down on the accelerator and its as though my car is standing still then a few seconds later the accelerate starts to work and move the car, this has happened a few times and i have almost been hit from behind because of this. i no longer drive my car on the highways because i'm terrified that this will happen again while on the highway and i will be crashed or even killed due to what ever is going on with my car
When i push on gas, the car never shifts gears! i can start out slowly with a little gas peddle pressure, but when trying to get up to speed and merge with traffic, it will never shift into a higher gear! it stays at about 20mph and engine revs to red zone unless i lift off gas. i don't even get gas peddle half way down. transmission roars, car doesn't go, and i can't go forward but at a slow crawl unless i pull over, let off gas completely so car can settle, then try again. it won't shift in awd or 4wd and i old lady, i don't troomp n rocket. i just want to get up to 55mph within 1 mile without sending my engine into dragonflies and half a tank of gas gone! i asked dealer and he blew it off as a slow startingvehicle, but it's getting worse and tyranny not shifting right. have to find a mitsubishi service center.
