#2209 of 2260 1999 honda accord trans
May 05, 2012 (5:38 am)
Hi, thanks for all contributions to this great form.
There is 99 Honda accord, when it is shifting at the take off, it makes a clunk noise. This also happens when you make a full stop. I showed it to mechanics and had different opinions. One told transmission should be replaced, inside is bad. Other told one of sensors is not working well, so it is not shifting properly.
Do you have an suggestion about what is going on, and what is the best way to detect what the real problem is?

The locks do work from the inside, as do the windows, but thanks for your tip, George.
I wish I knew if the remote entry problem could be related to the ignition switch so that I could decide whether to keep pressuring the original mechanic to fix it. It's frustrating to have the car come out of the shop with things broken that weren't broken before!

Are you talking about an actual metallic clunk you can hear, or just a harsh shift up and down?

I'm sorry you are having such a mysterious problem. I can't help but think something is wrong with the remote. I know you replaced the battery but why not see if the dealer has some way to check the remote unit or is there a universal remote or something they have that can prove that your car system is good or bad. There must be some way to prove one or the other is bad. A HONDA dealer can't be that inefficient but many are.

Having a starting problem again. I tried opening and then re-closing the gas cap like a family member suggested, that didn't work. It was almost 90 degrees here today, so maybe that is the problem? I think I read somewhere about people having a similar issue in warm weather. Any other suggestions as to what the issue might be?

Accords are pretty famous for having problems with the fuel pump relays, especially in hot weather. Sometimes you can hear if you have a problem. Open the trunk lid so you can get your head down right over the gas tank. Have someone turn the key to the on position, but do not try to engage the starter. You should hear a short buzzing sound as the fuel pump comes on to build up pressure in the system. The sound should stop after a second or two. If you don't hear this at all, it's possible that the relay is defective and the fuel pump is not operating. If the relay is the problem, it isn't too difficult to replace yourself, or any reputable garage should be able to take care of it for you. Good luck,.

Suddenly my Accord 2000 EX V6 check engine light on (I reset it and it is back on after a few days). And more importantly, mileage suddenly drop to around 9 mpg!

Well the clue is the check engine light, so get the car scanned.
Offhand, could be lots of things---bad 02 sensor might do that, leaking injectors, low compression, faulty timing....
You might check your oil and if the dipstick is way overfill, that would be a big hint for us.
But by all means, have a scan done. I think OReilly and Autozone still do them for free for you...and GET THE NUMBER of the code when you come back here.

Engine code: P0401. Exhause Gas Recirculation Flow Insufficient Detected.
With very low gas mileage, any educated guess on what goes wrong?

Bad egr valve, plugged egr tube----sure, that'll contribute to bad gas mileage depending on how the EGR is stuck---if open, that's not so good.
I can't say that the effect on MPG would be drastic, but it's a good first step. You might also want to check when you had your last tune-up and/or compression test.
also check your dip stick for signs of overfill--you could be leaking fuel into the crankcase from leaking/dripping injectors.
