Car Forum / Honda Cars / August 20042000 honda accord se hesitating
My accord always hesitates for a moment (less than a second) soon after I first start driving it. I would say I drive maybe 1-2km and then the engine for just a moment appears to almost stall then runs perfectly. This only happens when the car has sat for a long enough period to cool off fully. It has no other problems and it works fine if I were to be on a lengthy drive say 500km or more, just that initial "almost stall" and then recovery. By the way its a 5 speed 4 cylinder, around 90000km. Anyone have any ideas? > My accord always hesitates for a moment (less than a second) soon after I > first start driving it.

You should have your fuel filter replaced during your next scheduled oil change. Also, buy a can or bottle of a chemical that you pour into a full tank of gas that helps clean the fuel injection system. Also, incorrect timing can cause this problem. If the above suggestions don't solve the problem try resetting the timing, changing the spark plugs and checking for any air leaks.

How would any of these suggestions correct the problem his car is demonstrating? Per Haynes: "Engine stumbles on accelleration": spark plugs fouled Fuel Injection System faulty Fue filter clogged Incorrect ignitiion timing intake manifold air leak Didn't see any diagnostic guide in the factory service manual. Thanks for the input everyone, I can try everything here but the timing. It is almost due for a new timing belt anyhow, but I'll leave that job to the experts. > Per Haynes: "Engine stumbles on accelleration": > spark plugs fouled [quoted text clipped - 4 lines] > > Didn't see any diagnostic guide in the factory service manual. > Thanks for the input everyone, I can try everything here but the timing. > It is almost due for a new timing belt anyhow, but I'll leave that job to [quoted text clipped - 8 lines] > > > > Didn't see any diagnostic guide in the factory service manual. Appears to be a great plan. SignatureNEWSGROUP SUBSCRIBERS MOTTO We respect those subscribers that ask for advice or provide advice.

That all implies a persistent condition, the OP reports one nonrecurring event with each start. > Per Haynes: "Engine stumbles on accelleration": > spark plugs fouled [quoted text clipped - 4 lines] > > Didn't see any diagnostic guide in the factory service manual. I should have mentioned that I got the information in my post the same place where you got the same information in your post.

What is your solution for the problem? As most any mechanic will tell you, the same factors that cause an engine to "stumble upon acceleration" can also cause an engine to "hesitate". Obviously, just as doctors disagree on solutions to a medical problem, I'm sure that mechanics disagree on solutions to an engine related problem. It's a lot easier to criticize those that provide advice than it is to provide advice. SignatureNEWSGROUP SUBSCRIBERS MOTTO We respect those subscribers that ask for advice or provide advice.

Do they mean "just at start up", "always", "internmintent". etc. I am not an expert but if any of that stuff hasn't been done as per maintenance schedule - it seems like unwasted money to bring the auto into a "known" state. Reminds me of my sister wanting me to help her fix her PC when she wasnt willing to purchase a anti virus program and a virus checker (not fixer) had determined there was 32 viruss resident in her system. >I interpret hestation as the same as stumbling. Is there a >difference? Stumbling on acceleration means every time one presses the accelerator pedal the engine misses as it runs up, the OP described a condition where, once per start cycle and only when cold, his car seems to hesitate, momentarily loses power, without regard to accelerative state. >Haynes does not quantify the condition. Do they mean "just at start >up", "always", "internmintent". etc. ...Hence Haynes is neither a comprehensive nor exhaustive resource. >I am not an expert but if any of that stuff hasn't been done as per >maintenance schedule - it seems like unwasted money to bring the auto [quoted text clipped - 4 lines] >(not fixer) had determined there was 32 viruss resident in her >system. Did you start replacing the component parts of her computer willy-nilly *before* properly analysing her system and its faults? Would blindly replacing the floppy drive, simply because it was the easiest thing to do, ever have been the proper course of action? ...That exactly is what is being recommended here, by some. >> >> Per Haynes: "Engine stumbles on accelleration": >> >> spark plugs fouled [quoted text clipped - 12 lines] > >What is your solution for the problem? It happens once per start cycle, in a known state, and only when cool. Sounds to me like a position or temperature or O2 senor, or some other such ECM input device is failing, in a way that subtly interrupts the smooth transition from open to closed state operation. >As most any mechanic will tell you, >the same factors that cause an engine to "stumble upon acceleration" can >also cause an engine to "hesitate". Obviously, just as doctors disagree on >solutions to a medical problem, I'm sure that mechanics disagree on >solutions to an engine related problem. There is an INCREDIBLY simple solution which obviates such shade tree pickle barrel conjecture: OBD-II. This machine is controlled by several digital computers and an intricate web of sensory input devices. The correct way to diagnose which systems and device is faulty is NOT to easter egg through a laundry list of outdated shad tree voodoo machinations, but for a trained operator to hook it up to an OBD-II interpreter. Trained OBD-II operators can be found at any licensed repair station. >It's a lot easier to criticize >those that provide advice than it is to provide advice. It's seems even easier to dispense worthless and/or misleading advice, rather than to think rationally. |
