Mitsubishi Repair: 02 montero sport, kinds of sensors, montero sport

Question
QUESTION: From a stopped position, like a red light or a stop sign, when I press the gas to accelerate through the gears everything is fine until i let off the gas to coast,then unless i come to another stop, when I step on the gas again there is a hesitation feeling (no acceleration). It is almost like the gears have to reset them selves at the stopped position then they are fine.

ANSWER: Jason: Are you thinking this is caused by the engine or the transmission? Is there is any other problems with either or both? I would have the computer coded, the computer controls everything with the help of all kinds of sensors through out the engine and transmission. Still if there is a hesitation feeling could be the fuel pump is not putting out enough fuel. But you can have that tested too, to make sure the pump is putting out enough pressure. You know don't you that the pump is cooled by the fuel, you never should let your car get down below 1/4 of a tank. But with this high cost of fuel, a lot of people are trying to get all they can get out of that fuel and so been replacing a lot of fuel pumps of late. Still if you get the computer coded, it might kick out what is going on with the hesitation as to the engine running to lean or to rich. If you have an AutoZone close by they will code your car for free. Also get that fuel pump checked too. Hope this helps and God bless: Linda

QUESTION: Thank you for your response. I will have the computer looked at. One other thing that i noticed this week was that some times my engine will rev up to 4500 or 5000 rpm before it changes gears(usually third gear ) I don't feel any slipping and some times when i step on the gas it appears as though the rpm's actually go down until i really give it some gas then the gear seems to change and rpms go back up. thank you again for your help.

Answer
Jason: You need to get that looked at like now, because that is the computer doing that and soon it will put the transmission into what is called "Safe Mode" then the transmission will only shift to three gear and go no farther. There must be a problem in the transmission that the computer is picking up. I would also get the transmission fluid and filter changed too. You know these cars are to use a high cost transmission fluid, it costs around $7.00 a bottle. But a lot of shops don't bother to put in the right kind and so with time that will cook the transmission. So get the fluid and filter changed make sure they put in the right fluid for your car. Please don't put this off. God bless: Linda
