Common problems with 92 honda 5 speed

check the engine coolant temp sensor located under the distributor. if it is plugged in good, then ohm it to make sure it is sending the correct reading to the ecm. a bad ect can cause the engine to run rich.

You have an older OBDI car. Take the car to a parts store and have them read the code. Not all stores carry the OBDI readers anymore so call first. You could have anything from a bad trans to bad speed sensors. The code will help.

If it does that when the engine is warmed up (full operating temp.) it may be you iac valve, or your fast idle valve. They get gummed up. It also could be your PVC valve, but probably not.:


IAC in red. Fast Idle in yellow. Your PVC valve is plugged into the valve cover (the black hose in between the red and yellow in the picture) it simply pulls out. It should rattle when shaken.
Hope this gives you a start on the problem.

D4 is slipping and not engaging. This means you need a transmission. you're losing a gear

check the main relay

Change the ignition switch at key.

The Honda Civic Repairs site has some decent pics on its site:

First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,
