Jan 7, 2004 at stop light turned right and had my foot to the floor truck not moving more than 10 mls an hour. Service engine light on and reduced engine power on. The truck was serviced throttle switch was cracked and replaced. Jan 14, 2004 I warmed truck for 10 min before pulling out, drove for 15 min came to stop in traffic truck putted stalled. No lights lit up on dash. It started up but felt hesitation the rpms didnT seem to level on return to truck I let it warm 15 min and gave it a little gas putting the truck in drive it putted stalled no indicator lights. It started up and when pulling out putted the rpms dropped feeling it was going to stall I punched the gas it caught. Jan 19 & Jan 20 dealership 7am and left my truck for service. I noticed that heater levels 1, 2 had blowing. I rcd a call was told the fuel injector regulator had leak would need to be replaced. Truck was held over night wouldnT be ready for pick up until next afternoon. Asked if was the reason for stalling - said it may be they could not reenact the stall  but a leak in that part might cause stall. Jan 21, 2004 on start up service 4WD light came on. The indicator light above the 4WD switch was not lit. I shut off and opened door thinking it might re-up computer. The service light (yellow) was on and no indication of what I was in. I called dealership was told that I could drive the car as long as the light was not red. Jan 23, 2004 truck dropped off for service - spoke w mgr of my concern about this truck. This was the third time in for service in as many weeks. Asked mgr if they could run a diagnostic test to make sure it was okay. I have safety concerns about driving it on the highway or long distances. Service completed; I was told that the tmc module in the computer had to be reset. I was not offered a rental either of the other times I had the truck in for service.
