Re: tune up question

["David Teitelbaum <jtrealty@xxxx>" <jtrealty@xxxx>]

You do not have to remove the intake manifold to do a tune-up although 
if you do it does make it a lot easier. If you do remove the intake 
manifold you should also replace the "O" rings on the water 
distribution pipe and the hoses on the water pump. Check the vacuum 
hoses to the valves on the water pipe and if hard or brittle replace 
them too. You will have to get the mixture unit out of the way and to 
do that you will also need to get the idle motor off too. Now you 
should replace the "O" ring on the tube going to the idle motor too. 
You can leave the tube in and just remove the idle motor and not 
remove the intake, you can get to all of the spark plugs and fuel 
injectors without removing the intake. If you replace the ignition 
wires you will have to loosen the mixture unit to move it a little so 
you can get to the distributer. If removing the fuel injectors you 
should replace the seals and any broken or missing clips. You will 
remove the cold start valve if you are removing the intake manifold 
and you should replace the seals for that too when reassembling. If 
you still have the origional water pump this would be a good time to 
replace it too since you are already there and it is a lot of work. Be 
prepared for the inevitable broken bolt if you go in that deep.
