I have a similar problem I researched in this topic:

http://www.2carpros.com/forum/2000-honda-accord--engine-rpm-fluctuation-vt152189.html

and i wanted to troubleshoot my problem prior to taking it in

When in idle, my car's rpms are fine, around 700

But when i shift into drive and reverse, the car jerks prior to driving off. it does it more in reverse than in drive, and at one point i've heard the car make a loud "click/snap" noise after shifting into reverse.

I had a complete flush of the tranny fluids done about a week and a half ago. but i noticed that its leaked small amounts of fluid since then. i havent been able to tell what kind of fluid it is, but when i figure it out, ill post back w/ an edit.

Plz help.

ty


***update***

its not leaking any fluids. and when i shift to reverse but keep the foot on the brake, it makes a noise similar to when you pull the e-brake up. like a crank almost, as if the tranny is having a hard time putting it in reverse.

the problem comes and goes and seems to occur more after driving for a long time. as of right now i'm trying to drive as little as possible before deciding whether or not i want to get another transmission or get another car all together.

So your car makes a bang nois when going into gear, more in reverse? Does teh trans slip? does it engage right away when put into gear? Sounds more like you have a bad motor mount or two. There are "torque" mounts that keep the engine from moving front to back in the car, they are usually the frst ones to go out.There are also 2 that the engine "hangs" by these will be damaged if the thers arent fixed

yeah its not a loud bang though, like a backfire. more of a cranking / clicking noise. it only makes the sound when i shift into reverse. the trans does slip / jerk when shifted into reverse and park. more in reverse though.

now as far as fixing these "torque mounts" how much does that usually run?

also,the rpms do fluctuate during driving in certain gears, which lead me to believe this is a trans problem.

You do say that it does this more hot, which is usually when a trans will slip or have issues if it is just starting to need work.Is the check engine light on? Sometimes if the PCm detects a problem with the trans it will set a code

Yes, the check engine light came on just recently. I plan on having it checked out.

Btw, if it is an internal trans problem, is it better going with a rebuilt trans or swapping in an old one with a few months warranty.

Also, are both of these choices bad compared to getting a new Hybrid car that runs on a PSD trans

ty for your help so far

Have it scanned for codes, this may lead to an easy fix for the trans.The used trans wont have as long a warranty as a rebuild,but will be less expensive, your call on that one.

here's the only code that came up

P1149 Manufacturer control fuel air metering




this is the info i got from another site. tell me if this is right and see if you explain it in laymen terms for me =o)

------------------------------------------------------
One thing to check on is your warranty.
If I am not mistaken, the ECM is covered under the emissions warranty and may still be under warranty. You will need to check with your dealer to confirm that.

DTC P1149: A/F Sensor (Sensor 1) Range/Performance Problem
DTC P1165: A/F Sensor (Sensor 1) Range/Performance Problem
NOTE: If some of the DTCs listed below are stored at the same time as DTC P1149 or P1165, troubleshoot those DTCs first, then troubleshoot DTC P1149 or P1165.
P0137, P0138: Secondary' HO(2)S (Sensor 2)
P0141: Secondary HO(2)S (sensor 2) Heater

Reset the ECM/PCM.
Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on.
Test-drive under following conditions.
55 mph (89 km/h ) steady speed
A/T in D4 position (M/T in 5th gear)
Until the readiness code or Temporary DTC P1149 (P1165) comes on
Is Temporary DTC P 1149 (P1165) indicated ?
YES - Replace the Primary HO(2)S (Sensor 1).
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C102 (located under the under-hood fuse/relay box), the primary HO(2)S relay, the primary HO(2)S (Sensor 1), and the ECM/PCM.
Check for a Temporary DTC with the scan tool.

Applies To:
1998-00 Accord L4 - ALL
MIL Comes On With DTC P1149
SYMPTOM
The MIL is on, and DTC P1149 (air/fuel ratio sensor range/performance problem) is set.
PROBABLE CAUSE
Under certain driving conditions, the ECM/PCM sets a false DTC P1149.
CORRECTIVE ACTION
Replace the ECM/PCM.
Out of warranty:
Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work.
DIAGNOSIS
Connect the PGM Tester to the vehicle's DLC (data link connector), and check for DTCs.
^ If DTC P1149 is stored, go to REPAIR PROCEDURE.
^ If another DTC is stored, go to the appropriate troubleshooting procedure in the service manual.

Hi poet2mc,

Seems it is either a HO2S or PCM problem and is not easy to isolate the problem. Reset the PCM and retest, you might need to replace the HO2S or use a known good PCM to test.
