My 1990 honda prelude 4ws si model that i just bought and just replaced the battery in and altanator in struggles to accelerate if i put my foot down but if i gently accelerate it still is verry sluggish but eventualy gets there . please HELP!

it is carburetored sounds to be the choke on it

freeze plugs are located along the block on any engine. it's a indented circle piece of metal that is press fit into the block along the water jacket so that it ill bust if the coolant freezes rather than busting your block. they usually rust rather than bust

there is a cable mounted on the altanator farsten by a 12mm nut if that is broken or not hooked up
unit will not charge. use a tester to check for continuety or chech conection on battery harness

simply unplug and use a 7/8 wrench and a lot of muscle use a small amount of anti seize during installation.

I only know about the dipstick for the automatic transmission.
It is located to the passenger side of center and is burried dwon very deep - you almost have to reach full-arms-length down, between hoses and air duct to reach it. It has a wire loop handle usually covered in orange/yellow rubber. All total it is about 6 inches long when removed. It is so hard to find that I thought mine was missing and bought another one before I found it.

no there is no easier way if he didnt put the pin to the cable back on it must be reattached

You need to check the tcm for codes too. The s3 light is like the check engine light for the tcm. The VSS code might be your problem.

all you in fo is not there if you said your battery was dead but you could jump it and it would run but not charge battery then you altanator is working but you have a dead seal in the battery replace battery and you will be fine but if you drive it to much with bad battery your altanator will go bad from over working

Go to your nearest Autozone or other parts house and buy an inexpensive plug gapper. I gap the Honda plugs at .045 .
