Honda civic high idle problem?
I have a 91 Honda civic the car has 254,000, I had a 1.5 with 84,000 miles on it installed. I have a high idle at start up and between shifting, it surges after warming up. Just this past week it is doing a little jerking as I drive. I do a lot of highway driving. Sometimes it seems like it has no power, it takes time to get up & go. I tried valve cover gasket kit. I disconnected the battery, cleaned the terminals. Now I get a different code, I forget what the code was. I tried fuel injection cleaner, gas moisture remover. No improvement. I'm only getting about 25 miles to gallon. Any suggestions would help. Thank You for your time Stewart.

Thoughts:
. Purge the cooling system of air, by filling the radiator with coolant until it comes out of the bleeder bolt. Air causes all sort of idle problems on Hondas. . Check for codes--very important. . Change the fuel filter, if it hasn't been changed in 48 months or 60,000 miles. Your Civic may be starving for fuel at high speeds. . Replace the spark plugs (NGK only), if they have not been changed in 3 years or 30,000 miles. . Check the Engine Coolant Temperature (ECT) Sensor. They can waste a tremendous amount of fuel, as can a failing oxygen sensor. |

Hi, I'm about at my wits end with this car. A problem that I'm having even after it was worked on is that when it cranks it's idling high, but when I go to restart it again after taking a short trip - it won't start. The car was taken to a mechanic with this problem and it was fixed initially...
My 2003 Honda Civic LX with 47,000 miles has worked perfectly until now. Since yesterday, every time I start it, the engine revs up to 3,000 rpm in neutral or park and 2,000 rpm if in drive. I can control the car with the brake, but it runs away with me if I stop braking. So I can't drive it...

91 Honda Civic, 1.5l, remains at high idle, 1000-1500 until manually turning off by depressing pedal. Once engine rev'ed over about 1500 does it again. Will not return to low idle on it's own. Does not surge like vac hose off. No engine code. If I disconnect the temp sensor at bottom of radiator...
