1991 Honda Accord Problems
RepairPal has identified the most common problems with the 1991 Honda Accord based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The exhaust recirculation valve (EGR) on the 1990-2007 Honda Accord V6 may fail, causing:
The EGR valve has open and closed positions, and opens or closes on command from the computer.
Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.
To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

These relays send power to the fuel pump and fuel injectors when the key is turned to the “ON” position. So, when they fail, there is no electrical current to the necessary fuel system components to send fuel into the engine, causing engine stalling or failure to start.
In this situation, there are many other possibilities, so testing components is vital for time and money savings.
If the relays test bad, they must be replaced with relays specific for that circuit.
To help prolong the life of your under-hood electrical components, ensure the lid for the fuse block is closed, and any factory sealing material is correctly installed.
The Honda Accord is known for premature alternator bearing failure. The alternator shaft bearing alerts of mechanical failure by making a howling or grinding noise, but other symptoms may appear, including:
The correction is to replace the alternator immediately.
Four cylinder models of the Honda Accord from 1990-2001 have a known issue with ignition distributor shaft bearing failure, which causes:
The ignition system uses the distributor to send high voltage electricity to the spark plugs at the right time. It accomplishes this timing mechanically by a shaft, which connects the crankshaft and ignition distributor, so they spin at the same rate. That shaft, part of the distributor, rests in a bearing inside the distributor.This bearing, the distributor shaft bearing, is known for failing, and allowing the shaft to move slightly.
As the bearing fails, it allows the shaft to move away from the shaft seal, and oil pours into the distributor cap, causing misfires.
The play in the shaft can also cause contact with the crankshaft position sensor, causing a no start problem.
Total bearing failure will be most evident from the grinding noise that changes with engine speed, and oil in the ignition distributor cap.
If the bearing is making noise, driving or running the vehicle can result in catastrophic engine failure.
To correct this issue, the ignition distributor and shaft must be replaced. Any damage to the crankshaft position sensor will necessitate replacement as well.
The temperature control knob may break, requiring replacement.
Head gasket failure is not uncommon if the engine overheats. If the temperature climbs above the normal operating temperature, turn the heater on the hottest setting, pull over to a safe location, and shut the engine off to allow the engine to cool down.
On some models moisture could make its way into the rear wheel bearing, which would lead to noise. Rear wheel bearing and dust cap replacement will be needed for this repair.
