SOURCE: puting vac hoses back on and carberater on a 1984

The engine and emission control system covered by this information operate on a combination of vacuum and electrical signals; they are extremely prone to malfunctions due to improper vacuum connections. If a component does not receive vacuum at the correct time, it cannot function when needed. When working under the hood, pay close attention to the routing and placement of every hose.

I have a 90 Honda Prelude si and steam is coming from the over flow tank, but its not showing hot on the gauge.

Sounds like you are having a thermostat problem. It sounds like it is sticking at times and you may also have a bad temp. sensor. At times, if the thermostat sticks in the closed position, the sensor in the outlet side of the t-stat housing will not read the proper engine temp..Next time it gives you problems, lift the hood and carefully check the temp. of both of the water hoses to the radiator. If the top hose feels hot and the lower hose is only warm, then the t-stat. is stuck in the closed position and needs to be replaced.

How do you get to the speed sensor on a 1990 honda prelude?

I had to take my whole breather assembly out to reach it. Once out it will be on top of your transaxle but its still a little tough to get to because of the hoses on top of it. It took about 2 hours to replace.

Where is the transmission dipstick on a 1990 honda prelude si

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.

Honda prelude 1990

This prelude model on my experience the cause of in emission either map sensor near the throttle body and the small hose is connected. Next the coolant sensor below the distributor w/ two wires and the fuel pressure is cause by bad fuel pressure regulator at the end of fuel rail or the fuel return line closed. I hope this will give help to you.
