Question about 1994 Honda Civic

1 Answer

Honda accord 1900

I live in Florida so is hot. The engine does not need high temperature to be hot to run properly. When I start the engine it starts to accelerat it self from 900 rpm to 2000 and it does not stop even when the temperature of the water reach to proper function for the engine. So I need to adjust the part (I don't know the name ) so It should start to accelerat by it self at a lower temperature. Thanks in advance for any advice.

Well for the person in florida, if you have high idle even when it's warm out then that may be that there is carbon build up on the throttle body/throttle plate and it's causing some hight idle which is known to happen a lot on older toyota's especially. If u open the throttle plate and spray carb cleaner in there and wipe away the carbon deposits with a rag and make that area shiny u may see a difference.... As for the other person in Indianapolis, if you're having the problem during the winter then that is probably the IAC (Idle Air Control) valve which is connected to the intake manifold. If this gets build up of carbon and starts to make the valves stick in that IAC it could cause some irragular idle problems like as u described. I had a very similar problem in my 92 Acura Integra and I replaced the IAC and the problem went away, but i also know that u can sometimes spray inside the IAC with brake clean or carb clean and u may sometimes be able to free up the valves and fix the situation and be fine for a while, tho it may not be a perminate fix; however u will at least know for sure that was the problem..hope this helps u both, good luck

How to know if thermsat need change on Honda accord v6


1. If your coolant temperature is high your engine will overheat and you may have a faulty thermostat . However overheating may also be caused by other issues such as a failed water pump, blockages in the cooling system, a compression leak into the cooling system and other issues.

2. When the engine is fully cold open the hood and locate the top radiator hose running between the top of the radiator and the engine. Start the car and then feel the top hose. It should stay cool for a short time while the coolant gets to operating temperature and then the thermostat will open. When it opens the hot coolant from the engine will flow through the top hose into the radiator and you should feel the hose warm up very fast. This is an indication that the thermostat is operating normally but it is still possible that it is stuck partly open (when it should be fully open) and is impeding the flow of hot coolant from the engine. In that event it would need to be changed.

If you start the engine and you almost immediately feel hot coolant running through the top radiator hose the thermostat may not be closing at all and may be stuck fully open or partly open. It would then need to be changed. If stuck fully open the engine will run too cold some of the time and inefficiently, especially if the outside air temperature is very cold. But if a thermo is stuck fully closed or partially closed this will cause the engine to overheat and engine damage will result.

To properly test a thermostat it really needs to be removed from the engine. Please read the section in the link on Thermostats.

Someone recommended that I use 20-50. Oil on my 1999 Honda .accord with 133, 000 on it


I would NOT recommend using 20w-50 oil in your Accord at all. The manufacturers state a certain multi-viscosity oil to use in all their vehicles and you should stay with that. Many cars use a 5w-30,5w-20 oil and some should use a 0w-20 oil. Modern engines have tighter tolerances on the internal moving parts of the engine than engines from the 1970's and 1980's. A 20w-50 oil is way too high a viscosity(thickness) to use in todays engines. The first number, say 5w, is the cold start viscosity of the oil so the engine can start easier and have lubrication in cold(winter) temperatures. The second number, say 30, is the viscosity of the oil when the engine warms up to normal operating temperature. The oils have viscosity modifiers in them so as the engine and oil temperatures change(cold to hot, hot to cold), the engine has the lubrication protection it needs to operate correctly. I recommend using a synthetic blend oil that is found in many of todays engines right from the factory and stay with the viscosity that the manufacturer recommends in the owners manual. If you do not have an owners manual, call the dealer service department and ask them.

Car starts fine and runs fine- but won't start when it is hot


Try changing the coolant temperature sensor, it regulates the air fuel mixture when the engine is hot or cold.

1991 honda accord lx cooling fan


Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine. This can prevent hard starting that can happen with a hot engine. If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing. Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.

Turned car off...sounded like it's trying to start w/o keys


This is called run on,or dieseling ,there maybe a timing problem,or the vehicle is running to hot,the temperature is to high,it may not be cooling good,check the temp of the engine,if it is too hot,then the cooling fan may not be working,or thermostat maybe staying closed.If the vehicles throttle is staying open to much,this could be the problem also.

Hard to start in hot weather


Start looking at temperature sensors and maybe even the thermostat.

Sometimes the engine doesn't start and the spark plugs are wet


Change cap & plug wires. If emergency before wire & cap repalcement, spray wires & cap with WD-40, let sit a few minutes & try it. WD-40 displaces moisture. Don't keep doing that though, its dangerous, just replace wires & cap.

1992 accord running hot


Check the cooling fan switch and the temperature control switch, they should be turning your fan on when the engine temp begins to rise (as when u stop and gauge starts to climb).

Do you I need to replace the thermostat on my 1999 Honda Accord as a preventative measure only?


No only if you have noticed a change in engine running temperature on gauge, colder or hotter than normal.
