Need help, loss of power/stalling out
I posted on this a little bit before, but this time I was actually in the car when it was doing it, and now its doing it consistently.. so to start off this is a 03 Intrepid, with the damn 2.7, lol. So what it does, is it loses power, when your driving the rpm gauge will go crazy, and the car will act like someones giving it gas, then lettin off, then giving it gas then lettin off (but they're not), like the power kicks in and out, in and out. when its parked and started the idle is very rough like it wants to stall out, and now it actually will. put if you put it in Drive, and are not movin and hold your foot on the break, it'll do the vroom, nothin, vroom, nothin, vroom, nothin, with a real jerky feeling thru the whole car. Im really hoping this is some kind of sensor... maybe the AIC, or the fuel ratio sensor or oxygen sensor or whatever. I really don't know. but as of now the car will not even stay idling, it will start right up but then immediatley stall if you don't give it any gas. I'd appreciate any help or suggestions as my wife needs this car for work. Also, absolutely no codes pop up.. was really hopin some would so I would have a direction to go in. when the car did this before, it'd do it for a min, and then would be fine for a week or so, then do it again, and then be fine for another week, now its consistent. so obviously somethin has been goin out, just don't know what. tryin to avoid the shops if I can, don't wanna pay that kinda money if its somethin I can fix myself.
