1999 Honda Accord - Page 3 - Answered Questions & Fixed issues

there could be a slight hole in one of the air intale hoses and can only be heard at idle as drowned out by engine noise , i'd get the OBD codes read this should tell you which , if any , sensor/switch etc could be causing this issue, keep me posted if you wish

look for a vac hoes leak

First thing I'd do is look at the VSS (Vehicle speed sensor). Do a GOOGLE search for 1999 Honda Accord Speed sensor and you'll pull up You Tube videos on how to do this.

With a scanner, you can open and close the IACV. Most times it is just dirty. Remove it from the throttle body. use brake clean and soft brush to clean most of it. The n open it up and use a tooth pick or paperclip to clean the inside.

From Helms manual (factory shop manual) Rod, FI engine: 34 lbs Rod, Carb engine: 23 lbs (I use blue thread locker on rod caps) Crank caps: 51 lbs. (oil threads and under bolt head)

linkage that connects the motor to the arms, stripped or loose.

Most fuses are in the engine compartment on the drivers side near the firewall. Some are under the dash next to the driver. Hope this helps.

I would NOT recommend using 20w-50 oil in your Accord at all. The manufacturers state a certain multi-viscosity oil to use in all their vehicles and you should stay with that. Many cars use a 5w-30,5w-20 oil and some should use a 0w-20 oil. Modern engines have tighter tolerances on the internal moving parts of the engine than engines from the 1970's and 1980's. A 20w-50 oil is way too high a viscosity(thickness) to use in todays engines. The first number, say 5w, is the cold start viscosity of the oil so the engine can start easier and have lubrication in cold(winter) temperatures. The second number, say 30, is the viscosity of the oil when the engine warms up to normal operating temperature. The oils have viscosity modifiers in them so as the engine and oil temperatures change(cold to hot, hot to cold), the engine has the lubrication protection it needs to operate correctly. I recommend using a synthetic blend oil that is found in many of todays engines right from the factory and stay with the viscosity that the manufacturer recommends in the owners manual. If you do not have an owners manual, call the dealer service department and ask them.

20w-50 grade oil will not hurt the engine provided that it is not used in very low ambient temp areas (15 degrees to - degrees) In these cases I would opt for a low viscosity oil like 10w-30 or at the lowest 15w-30 talk with a service centre dealer for recommended oil for cold /freezing condition

If the starter turns the engine over, then it could be not getting fuel or spark plug voltage. If not then it could be the battery or battery connections or a loose ground connection on the engine. It could also be no fuel pressure or the "Main Relay" is bad Hope this helps. .

HERE YOU GO.

Haines or Chilton repair manual for '99 Honda Accord will give you step by step instructions for timing belt repair. It's a substantial job!!

did you open the rad drain and flush that way or take the hose off the bottom of the rad. sounds like you may have more than just water pump issues could be head gasket, take off oil filler cap there is white milky slime it could be head gasket make sure you locate the leak or it will all be coming apart again anyway. make sure the timing marks are correct when you put it back together

Too many things to trouble shoot here. The first things I would check would be the door switches one by one in a series of opening and closing them individually. The next thing would be the dash control for the interior lights. The next would be the body computer and would not be a bad thing to check your fuse distribution panel either for shorts.

Your best bet is to go to a parts house and buy a rebuilt torque converter. Make sure you save the old one because they will likely require a core.

Definitely transmission problems P0740 Torque Converter Clutch Circuit Malfunction P0730 OBD II Trouble Code Unfortunately most transmission shops will say "needs a rebuild". Sometimes you can get a low mileage transmission out of a wrecked car, but the install labor isn't cheap.

need to know if it is 4 or 6 cylinder

if you pressure washed you car check your spark plugs

if you have a pioneer deck then pioneer tends to mute if there is positive line of the speakers hitting ground

it has a chipped key so no one can just drive off with it ,do what i do and leave the doors open and nothing inside ,then they dont damage the vehicle
