1999 Honda Accord hesitation/stall
Ok... I have a 1999 Honda Acord 2.3 liter V-Tech, 140k. About 3 weeks ago I noticed that when I started my car up and it was cold I would put it in to gear and the engine would start to chug at really low rpms. I would throw it and neautral and push the gas and nothing would happen. The engine would chug and then die. I then would start it up again and typically could make it out of the driveway. While driving I noticed that the acceleration didn't seem normal as Accords are typically pretty snappy. As I drive I step pretty hard on the accelerator and the rpms stay low like i'm pulling a ten ton anchor behind my car. As I'm holding the pedal down I can feel the engine trying to kick up the rpm's as there is some speratic increase in speed and rpms as the engine trys to get going. If I accelerate slowly It's much less noticable.
Ran the codes and I get the classic EVAP code that from what I can tell is just a bad gas cap, so they say. Also had a 02 sensor code pop up for bank 1 sensor 1 and I replaced that but unfortunately no change in how the car is acting. I've cleaned the Idle Air Control Valve and it seemed to change up the idle for a second or two but ultimately did not fix the hesitation or periodic chugging at stops. I'm thinking of just replacing the IACV all together. I Changed plugs, cables, etc. Timing and pretty much everything else has been checked. Something is telling me there is a air/gas flow issue and maybe that could explain why when I accelerate fast its not getting up and going, and when I put it in gear or stop peridically it wants to chugg and stall because it's not controlling the flow properly.
When it is not in gear and was previous idling normally, there is no problem with hesitation and the rpms shoot up like normal. It seems that its only when torque is placed on the engine it's having issues.
RPM's are running normal level in the 800 - 1000 range when warmed up.
I've read many of the threads but I can't seem to find anyone with the same symptoms I'm having.
Here are the codes it pulled:
P0131 - 02 Circuit Low Voltage - Bank 1, Sensor 1.
- Replaced the 02 sensor up by the manifold (no change in symptoms)
P1457 - EVAP Emmission Control Leak Detected - Control Canister System.
- Was told that it most likely was a gas cap and typically wouldn't cause the problems I'm describing above.
Any thoughts?
Thanks,
Mike

Re: 1999 Honda Accord hesitation/stall
I need some help please. Sorry to be that guy to bump... if you need additional info please let me know. If itsounds that difficult (considering its not pulling a easy code) please let me know. Maybe its time to take it to a dealership. Any help is welcome.

Re: 1999 Honda Accord hesitation/stall
well theirs basic stuff to check like is it getting oxygen, is it receiving enough spark?, is it getting fuel? those are the three main things to look for in diagnosing any engine problem, pullout the repair manual and start researching, could be a series of problem

Re: 1999 Honda Accord hesitation/stall
Fuel flow seems fine, plenty of spark since wires, plugs have been replaced and injectors have been cleaned. It seems like a computer flow for air or gas is out, any ideas. If you need more info, please let me know. Does the IACV sound like problem? Will it cause the fast acceleration hesitation?

Re: 1999 Honda Accord hesitation/stall
Get rid of both codes. If there is a CEL, something is wrong and needs to be fixed. Fix both issues and reset the ECU. Do a compression test to rule out anything large. Could be a potential fuel delivery issue.

Re: 1999 Honda Accord hesitation/stall
If I replace the 02 sensor and dont clear codes, can that cause it still to have problem s? I figured if you fix the code by replacing the part it wouldnt matter, right? Compression seems fine, nothing abnormal. Seems electronically something is starving it of fuel or air.

The art of troubleshooting is one that is overlooked by impatient people (namely myself) wanting to fix the problem for what they "think" is wrong. Every once in a while I still end up replacing the wrong part because I don't troubleshoot the issue properly, or all the way. You need to troubleshoot these issues if you replaced the part and it didn't do anything.

Troubleshoot? The reason I'm here is because my troubleshooting is not working. I'm not looking for useless advice. I'm looking for some ideas on what part may be malfunctioning given the symptoms I described in my first post. I mean really... troubleshoot is all you have?

Re: 1999 Honda Accord hesitation/stall
From what I'm reading, it sounds like a fuel issue. You might not be getting enough fuel volume when you accelerate. Maybe your fuel pump is starting to fail....my 2 cents.

Re: 1999 Honda Accord hesitation/stall
I was referring to myself so I hope you didn't take my comment personally. The jist of my post wasn't "useless advice". The point was to give you a heads up not to buy any more things to replace (plugs and wires as previously listed in your first post) because you think it could be the problem. Just trying to save you some $ is all.
As for troubleshooting the codes: Yes. I mean troubleshoot.
I can't post the PDF links because I am work. There are two PDFs that address the emissions code if you scroll down the page in the link below.

And the 02 code-

That being said, these might not be the reason your car is running bad but they ARE problems. If it were me, I would start here. Good luck.

Re: 1999 Honda Accord hesitation/stall
I keep my car very well maintained. It has a tune up and parts are maticulously replaced. I follow honda maintence and replacement guidelines to a "T". I think I've figured out that the car is not getting enough fuel when it needs it. If I put the vehicle in neutral and rev to 5k RPMS it runs perfectly. If I put it in gear, start driving, and step on it. The car struggles to increase RPM. Like not enough fuel is being dumped when the engine is really working but there is just enough when it's in neutral that you don't notice it.
Is it possible that a vehicle still runs and drives but when a higher demand for fuel like a hard acceleration it holds back and struggles?
Any thoughts?
Fuel Pressure Regulator?

Re: 1999 Honda Accord hesitation/stall
OP, this sounds like a knock sensor issue. I'm too lazy atm to look up if you have one, but if I was you I would check and see if your motor has one. If so, replace it and see what happens.
