1997 Rodeo idling problem update

as stated in a previous thread,i have a 97 rodeo 2.6 4cyl-5speed 2wheel drive.it runs great for about 4 or 5 days and then it starts idling at about 3000 rpm and then it will stall and wont start for about 10 minutes.i took it the other day and had it put on a computer and was told it had a bad throttle position sensor,bad cam sensor and a bad crank sensor.all of these have been replaced with new sensors from napa right before i bought it.crank sensor has been replaced twice.it has a new distributor and battery also.is it possible the choke is sticking and when over reving its flooding out also causing it to die.by the way the garage said its a bad computer but it seems to me it wouldnt run as good as it does if the ecm was bad.just wondering if the garage is trying to screw me for a 550.00 computer.
