Question about 1993 Honda Accord

1 Answer

RPM's are jumping around at high sppeds

I have a 1993 Honda Accord Anniversary Edition. We had oil in the spark plugs so we changed the valvue cover and spark plug gaskets and seals, put in new spark plugs and spark plug wires. Still when we are at a stop the engine idols slow and the check engine light comes on. Then the other day going down the freeway at about 60 and 3000 rpm the rpms started to bounce up and down eratically. The check engine light is still a code 6, which is a temp. sensor, but the sensor is testing good. We have two questions. First any idea on what the problem could be and second how do we clear any stored codes.

You can clear codes by uncoupling the negative battery cable for thirty seconds

    The temp sending unit directs the throttle position sensor to put the choke on or not. If the choke is on and not on your RPMS will jump. This could be caused by a bad thermostat, air in the coolant system [some Hondas have a bleeder valve], or a bad throttle position sensor. I would start by changing the thermostat. They are inexpensive and relatively easy to replace. you will find it in a housing where the top radiator hose meets the engine. Remove the bolts, lift off the cap of the housing. Remove the thermostat, be sure to remove any gasket material. Install the new thermostat and gasket, making sure that it is not upside down. If you don't know which way is up, ask the person at the auto parts store. The bleeder valve is usually on the engine block on the top. Reconnect the top hose and fill the coolant bottle with a 50/50 solution of the reccomended coolant to the cold level on the cars coolant container. Make sure the radiator and coolant bottle caps are on and tight. Start the car and wait until the coolant starts to ciculate, open the bleeder valve, watch for air to bubble out. When the air has stopped, close the valve and shut the car off. Carefully fill the coolant bottle to the hot level and you will be done. If you dont' want to do this first have someone test the TPS and go from there

1993 Honda accord 10th anniversary edition won't start, turns over, has spark & fuel pressure. 2.2 motor auto transmission.

These have a know issue with the Distributors.. You may be seeing a spark but the spark may be so weak that it is not sufficient to ignite the air/fuel mixture in a compressed environment.

I had this happen to my 1992 Honda. Cost me over $400 in Troubleshooting and nobody could figure it out. I went to one of my venders (Parts for Imports) and they enlightened me and sold me a New Distributor and installed it and BAM!!!! Ran like a top.

I did extensive Troubleshooting myself, ran into a brick wall because mine was doing the same... Good Fuel Pressure, Spark but Nothing.

One thing does come to mind that I tested mine and that is to do a Compression Test or pop the cover off the Timing Belt to see if it is Moving or if the Timing has jumped...

This Motor is an INTERFERENCE MOTOR, If the Belt Broke or Slipped, you could have caused some damage.

If you need any further assistance, please let me know. I have an extensive Background with Honda's... I certified as an ASE Mechanic in 1979 (Dang I am getting OLD)....

My 92 Honda seems to sputter at low rpm. Like when you first take off from a dead stop. I had the oil around spark plug problem like the others posted on here. I changed the gaskets, but it is still...

Did you change what's call the "tube seals". It should have came with your valve cover gasket kit. 4 rings that push into the valve cover... If you did this and you still have oil, maybe your plug wires are still wet inside. Is the fuel filter very old?

1992 honda accord dx burns oil

No, Just change your Valve Cover....sometimes the seal leak that is around the spark plug tube.. When you get the valve cover, make sure it comes with the four seals that goes over that area, because some kits, do not come with them

RPM's are jumping around at high speeds

Sounds like you may have a bad ground somewhere or a bad power connection.

I Have a 1993 honda accord ex.Just Changed the valve cover gasket! Checked the plug wires recently and the had oil all over them.What is the Problem?

When you changed the valve cover gasket, did you also change the seals that go around the spark plug holes? If you did,and theres still oil getting in there, they might have moved when you installed them. If thats the case, hold the seals in place with some RTV black sealant and try it again.

My 1993 Honda accord wont start, I replace the

I like to make sure the timing belt is not skipped or broken by watching the cam turn inside the valve cover. Then I lay a spare spark plug on valve cover connected to any plug wire to see if it sparks. Fuel can be confirmed by smelling the exhaust, or by using starting fluid . These cars are famous for a coil relay solder break problem. The relay is heat expansion damaged, its mounted high up in the dash drivers side corner it is about 3" square gray.

Oil around spark plugs on 1992 honda accord

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

1990 Honda Accord DX 5 speed no power/2 cylinders not firing? far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB

Spark plug well filling with oil.

a new valve cover gasket and o-rings around the wells should have cured this...did you clean the old o-rings off the valve cover completely before installing new ones? this is a common problem with these models.....i would re-check my gaskets and mateing surfaces. valve cover gaskets and spark plug well o-rings are relatively low cost. the spark plug is tight, correct? write back with an update!
