I have a 1999 Buick LaSabre with the 3800 engine.I need the Vacuum Hose Routing Diagram.Where can I get this online? Also,the above said car,is receiving way,way to much fuel,into the Cylinders, # 1 # 2 & # 3. If car does start ,it will run GREAT, but after its start running poorly.

To much GAS getting though to spark plugs. On Plugs # 1,#3,& # 5. I have to let the engine sit,for a while,before it will start p,and run.But,let it sit for a few minutes,and it does the same thing again.However,when it does start up,ot runs like new.WHAT IS GOING ON? CAN YOU HELP.I also need the VACUUM HOSE ROUTING DIAGRAM,for this car. THANK YOU ! this site is great!
