well the other day my truck started acting up.... it will idle fine in park or neutral but when i put it in gear it runs rough... some people are saying its the injectors and some the oil pump well its leaking oil and needs new glow plugs..

. i just put my car on ebay the other day and im hoping it sells for what im asking for it and if it does i think im jsut going to get another motor and put it in the trucks an early 99 and if i got a new motor does it have to be another early 99 or coud i be like an 03? would i need to make any modifications to make it run?
