Question about 1991 Honda Accord

1 Answer

In park rpm goes from 1100 to 2000

Well I went to change my thermostat and when I pulled the car up to the garage and put it in park the idle was surging up and down between 1100 and 2000 rpm. The car started overhaeting on the way home from work the other day and have not drivin it since I went to my garage. So I was starting with the thermosat and now I have another prob. Any help will be greatly appreciated, thank you.

Hondas will have a surging idle when way low on coolant. Maybe this is the whole problem. Check the heater hoses for a hole. (passenger side rear of engine.)

Stall on hot day after idling with ac on

Check the idle RPM and make sure it is set correctly as the ac will put a load on the engine and pull the RPM's down. Normally should be around 800 rpm's when in park.

Won t start

run the fault codes and look for faulty cam/ crank position sensor as this is indicated by the backfire/hard start and lower idle RPM. Check that battery terminals are clean and tight..

I recently purchased a 2002 mitisbushi lancer and the idle was going up and down. When i turned air conditioner on the idle went down, when i turned it off the idle went up. Now with that being said i put...

Disconnecting the battery will not delete stored fault history. It must be done with a CRT (Snap- On 3000) or equivalent. The idle condition you have now should be the opposite. 1200 RPM with air on 900 with air off. This vehicle is at an age where several components are probably out of range. I would try changing the cheapest parts first. 1 Fuel filter 2 Air filter 3 Thermostat For Coolant) 4 All coolant temp sensors (They can affect idle) 5 MAP sensor(manifold absolute pressure sensor) 6 Idle air motor. Sometimes the idle air motor can be cleaned . Check pintle and seat for carbon build up, clean with a valve guide brush. Pintle not seating will cause idle problems

Temp Gauge went to high

It could be 3 things: Temp sensor, thermostat, or fan relay. Fans don't usually turn on until car has been idleing for a while. I first would change thermostat, then relay, then temp sensor. Coolant must be 50/50 mixture for water pump to have proper lubricant from antifreezer. Do not go any further than a 60water/40antifreeze mix

While Idleing, My RPMs gauge goes up and down and continues until my car turns off. I put it in Park and restart it and it is fine until I am Idling again.

I had this same problem but the high rpm and thermostat indicator rise together if it does i would look at engine coolant temperature sensor your thermostat could be bad as well

is the blower motor or does it sound like the fan comes on. Draining of the battery i would look for a light on if its not the blower motor.
