Low / uneven idle problem can cause by a lot of components.

Dirty air filter

Dirty injectors + o-rings

Vacuum leak at intake manifold and vacuum hose.

Bad Idle Air Control Motor (IAC)

Low compression (170 psi + is OK)

Start cleaning and repair these trouble spots and see is there any improvement.

====

For more advance DIY'er then you may try this.

Use a can of Berryman carburetor clean to locate the vacuum leak.


SEE SAMPLE PICTURE HERE


This is a 20-30 minutes job.

Vacuum leaks can occur in following locations.


Intake manifold AND/OR vacuum lines.


Intake manifold is not accessible unless the engine head if off.

You can still check the potential leak by spraying some Berryman near the intake manifold.

Listen for rpm increase after you introduce the Berryman (FUEL) at idle.


Do the same starting from the brake booster unit (the round unit) on the drive side fire all.

Carefully listen for increase of RPM right after to spray the Berryman to the potential vacuum spot.

Get a friend to HEAR the ROM increase or monitor for RPM on the tech.

DO NOT AIM the Berryman into any heat source.


PLEASE RATE my answer if it is useful to you.

SOUNDS LIKE A VERY LOW IDLE AND THIS CREATES A LOW VOLTAGE THAT MAKES THE RELAY CLICK, DO THIS PROCEDURE:
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

I have a 97 Honda Accord that stalls in warm/hot weather after it had been sitting in a parking lot for 6-8 hours in the afternoon; never in the morning and never in the evening. It usually starts right up...


there's a main relay or fuel pump relay located under the dash on driver's side. this relay goes bad all the times. it usually goes bad when you leave the car in a hot sun, next time keep your window down to see if it will start.

Has anyone had a main relay problem with the 1999 honda accord?


It can be a faulty replay or your pump may be going bad. If this happens check first if there is gas coming out of the fuel filter or to the hose before it. It could also be caused by a clogged fuel filter. If there is no gas going to the fuel filter, have the relay for your fuel injection checked out. It is located under the driver side dash. Check also if you have any issues if your pump when directly connected to the battery.

1999 Honda accord coupe stalling randomly


this is your ignition switch failing. Typical symtoms when stalling, speedometer and tach dropping to zero(while in motion), some warning lights not lit, power failure. The internal contacts are shorting due to poor design and engineering. This causes vital engine/vehicle electrical failure, causing the stalling(happens more often in hotter/humid weather). There is a recall in place for this in 2002, over 1.5Million vehicles from 97-02 Honda2.gif/Acura models affected. Owners were notified in 2002!! If your vehicle is part of this recall, honda may repair for free. Call your local honda dealer with your VIN# at hand, they will give info on this recall and may repair for free. Otherwise the switch cost about $45-$95. hopefully this helps...please rate...thanks

Car randomly stalls when im driving... need to narrown it down


Please check your service record on when was the last fuel filter and fuel pump change.

Keep a record and see when the car is stilling.

A weak fuel pump like to fail when it's hot 90+ F or when the fuel is low.

The combination of this two factor and an old fuel filter will give you fuel delivery problem.

==
Right down the line is the fuel pump relay.
==

Don't over look it.

If you have a DVM meter then check for the voltage pin out for power to the fuel pump.

==

Is the an alarm in the picture? An ignition disable relay can also give you the same symptom. Contact the alarm profession who installed the alarm and go from there.


===
Keep the tank above 1/2 tank to rule out a weak fuel pump.

===
The electrical portion Ignition switch can be failing. Test it while your car is park on the drive way.

Tap and move the electrical portion of the ign. and see does it cut out.

I hope you can ran though these small tests and start monitor WHEN it's failing.

Please post your findings and I will follow up on it.


Good luck.

98 Accord won't start


Check the main relay-PGM-FI Main Relay, called a fuel injector relay(a gray little box with a plug at the end). To make sure it is a bad relay, do this: Turn the key to II, listen for a humming sound from behind you. It is a fuel pump working. You should hear a click under the dash after it. It is a main relay click . If you do not hear a click, you car will not start. If you do hear a click, you car will start.
Fix is to take the relay out, resolder the joints and put it back in. Go on www. MarkLamond.co.uk and http://techauto.awardspace.com both sites will show you how to resolder the main relay and where it is located if it is the PGM-FI Main relay.
