Question Answered: Why does the engine oil light come on after the car is warmed up at low rpm's?
January 04, 2012, 03:37 PM
I recommend doing a manual oil pressure test, installing a mechanical gauge and testing. Specifications are minimum of 5 psi hot idle and 25 psi to 80 psi at 2500 rpm's.

NOTE : Before removing nozzle assemblies, clean exterior of each nozzle assembly and the surrounding area with solvent to prevent entry of dirt into engine when nozzle assemblies are removed. Also, clean fuel inlet and fuel leak-off piping connections. Blow dry with compressed air. Remove and cap line sensor on number 1 cylinder to permit removal of fuel leak-off tee. REMOVAL Disconnect nozzle fuel inlet (high pressure) and fuel leak-off tees from each nozzle assembly and position out of the way. Cover open ends of fuel inlet lines and nozzles to prevent entry of dirt with fuel system protective cap set. Remove fuel leak-off lines as an assembly. Remove pump to fuel return tube hose at fuel return elbow cap elbow at pump. disconnect hose (from leak-off tee of fuel filter) at leak-off tee. Loosen two fuel return tube retaining clamps, one at intake manifold and one at engine lifting eye. Remove fuel return hose clamp at CDR valve bracket. With clamps removed, remove return lines and tees as an assembly by lifting tees off nozzles. Remove injection nozzles by turning counterclockwise. Pull nozzle assembly with copper washer from engine. Be careful not to strike nozzle tip against any hard surface during removal. Cover nozzle assembly fuel inlet opening and nozzle tip with plastic cap to prevent entry of dirt. NOTE : Remove copper injector nozzle gasket from nozzle bore with O-Ring tool T71P-19703-C or equivalent if not attached to the nozzle tip. Nozzle Holding Fixture Place nozzle assemblies in a fabricated holder as they are removed from the heads. The holds should be marked with numbers corresponding to the cylinder numbering of the engine. Use of this holder permits nozzle installation into original location in the cylinder heads. INSTALLATION Thoroughly clean nozzle bore in cylinder head before reinserting nozzle assembly with nozzle seat cleaner. Pay particular attention to seating surface, in order that no small particles of metal or carbon will cause assembly to be cocked or permit blow-by of combustion gases. Blow out particles with compressed air. Remove protective cap and install a new copper gasket nozzle assembly, with a small dab of polyethylene grease. NOTE : Anti-seize compound should be used on nozzle threads to aid installation and future removal. Install nozzle assembly into cylinder head nozzle bore. CAUTION : Be careful that nozzle tip does not strike against recess wall. Tighten nozzle assembly to 47 Nm (35 ft lb) . Remove protective caps from nozzle assemblies and fuel lines. Install leak-off tees and lines as an assembly by lowering onto nozzles. Connect clip and hose to fuel return elbow at pump. Install line to retaining clamps. NOTE : Install two new O-ring seals for each fuel return tee. Connect high pressure fuel line(s) and tighten to 30 Nm (22 ft lb) using fuel line nut wrench. Start engine. If necessary, purge high-pressure fuel lines of air by loosening connector one-half to one turn and cranking engine until bubble-free fuel flows from connection. WARNING: Keep eyes and hands away from fuel spray. Fuel spraying from partially opened connections under high pressure can penetrate the skin and cause infection. Medical attention should be provided immediately in the event of skin penetration. Check for fuel leakage at high-pressure connections.
Question Answered: rear end drops occasionally, has air suspension. How do I fix it?
January 04, 2012, 12:37 AM
I recommend spraying the air bags and componets with soapy water. You might want to take the car to a trusted repair shop familiar with this system due to it is hard to do without a drive on lift.
Question Answered: Why won't the turn signal blink but light bulb is on?
January 04, 2012, 12:31 AM
Sounds like bulb(s) are installed in the socket incorrectly or a defective light socket.
Question Answered: where does this hose connect to?
January 04, 2012, 12:28 AM
Do you have a check engine light? The hose sounds like the vent for the transmission and is suppose to be open. I recommend looking at the air intake duct hose from air cleaner/mass air sensor to engine and vent hoses branching off of that. Make sure there are no cracks or leaks.
Question Answered: I am not able to unlock the driver side door with the key, or manually.
January 04, 2012, 12:03 AM
Sounds like the latch/lock assembly is dirty, gummed up or defective. If your not familiar with removing the door panel, I recommend having a trusted repair shop give you an estimate.
