Hi I got a 99 and it doesn't seem like all the power is there its a v6, when I get on the gas is sputters and boggs kinda, there is a little knock in the motor. Any suggestions what I can do to get the power back in the v6. And how hard would it be to change from fuel injection to carbarated
They operate fine in back but not in front. As best as I can tell they do not light up or blink.
Can i hotwire the fuel injectors or install a inline fuel pump.

Tried replacement but those doors were just as bad

it has been doing it for about 3 weeks it is my wifes car she has to swipe her card to get into work she will roll the window down and then the radio goes off and she cant roll them back up. I have put my scanner on it and there are no error codes when it works and when it doesnt. some times its been off for 3 days other times they come back on in a few hrs. she has been driving and not useing the radio or windows and look down and the radio lights will be out and she checks the windows and they are out too. I was able to make it do it by rolling the passenger side window all the way down and then holding the button down a few secs more
I hope you can help me with this thanks
