:lol: that's funny, guys. yeah, i moved to LS400, but still driving the RL till it is sold.

to be honest, i don't know if to write about the solution here, because also acura america might read this info. and save a lot of money, which i spent on finding the source of this problem. and honda europe never gave a damn about my problems. they were ignoring me and my RL totally. they care only about those civics they sell over here. not about their best buy. talking bout customer relationship. so i'm pissed about honda right now and not willing to share any information with them. but i'm willing to help everyone of you as good as i can.
so if you have such problems, and you are sure it has nothing to do with the tranny or your suspension (it's easy to find out: if your engine vibrates in neutral and the car stands still, it must be the engine), send me a PM and i will do my best to give you some hints.

Well, then I guess mine is not the engine. Smooth as butter when in neutral. I'm leaning towards the torque converter as it's getting worse as the car ages. They looked at mounts and found nothing.

Any idea what a new torque converter is going to run? :bigcry:

I have a '96 Acura RL with high mileage (245k now) and about a year ago had a vibration problem. It only was apparent when the car was in gear, stopped, and I had my foot on the brake. If it was in neutral - no problem. No problem in park. Not noticeable when the car was cruising down the road. It was more like a shake than anything else. The cause was a faulty coil pack. It misfired at low RPM with a load on the engine. Changed the pack and the problem went away. $100 fix.

If it didn't throw a code, how did you know a coil pack was bad, and which one? Thanks.

If turn on the AC, it gets worse.

I have the same (side to side) engine vibe with my 97 RL for 2 years. I recently replaced both of the middle motor mounts due to the motor shaking so bad. It did help but still there and I'm afraid to drive it because it shakes so bad it may break the mounts again. they weren't cheap either. Only under acceleration & under a load. I've had it on a lift and with brake applied at the same time as the gas @ 1500-2500 rpm you can SEE the engine move side to side.
I serviced the trans,diff, tune up, fuel filter replaced pass axle due to boot, replaced both mid mounts, replaced 02's. I know axles can cause vibration, but this seems to be more than just axles, axle vibration usually knock and vibrate. I'm lost!

i know this is an older post, but i wanted to say i had major vibration problems recently. it felt like the car was going to shake itself apart abot 40 mph and explode at 60mph. i brought it to the shop expecting a series of problems.... turns out 1 wheel was loose and all 4 were out of balance. less than $25 to fix. now its smooth as can be. i've never realized tire balance could create should a major problem if out of spec. thought i'd share.

disconnect all O2 sensors and go for a ride. let's see, if the vibrations will go away.

Thats exactly it seamusnh. Same problem here except I still feel a slight
shake/vibration in park/neautral. How do we figure out which coil pack without a error code?

Yea mine too. Sounds like you have the same problem.

Are the connectors from the o/2s in front of the engine? In the service manual it shows the o2 sensors between the middle injectors. The wires from the sensors are they black, green and white? If I disconnected the correct connectors then it didn't work for me. Can you help me? Thank you for your time.

My educated guess is that it's the EGR valve

I had a 96 and had same symptoms. The EGR system was under warranty and Acura replaced EGR valve, all coils, new plugs. Problem went away.

If memory serves me, this may be the last year of the warranty. If you haven't had this service done, go to the dealer and them them. Recall was 98-???

Yea I received that warranty extension in the mail. I would have to travel 80 mi to the nearest Acura dealer. Then maybe have to take a day off. blah I changed the plugs and checked the egr valve it was fine and still the problem exists. It’s the beast I tell ya!! lol Wish someone would steal this beast already. bwahaha

 

[RLuke]

then there is only one last option for you: the exhaust manifolds are cracked/warped. take the covers down and check the manifolds bolts. if some of them are ripped off, then the manifolds are done. you need to replace them.

Hi Luke.
I sent you a PM re what to do if the vibration goes away when you unplug the O2 sensors. I hope that you're still checking this forum out from time to time.

 

[rboulware]

I had the same egr valve code on my 1996 rl. Did everything you did with no luck. Turns out my egr ports were clogged. A common problem with these cars. My car runs like new now.

FOR ALL OF YOU HAVING THIS UGLY VIBRATION PROBLEM:

try following:
-turn off engine and pop up the hood
-disconnect both O2 sensors (the connectors are in front of the cylinder heads on each side)
-start the engine
-MIL will come up (cause O2 sensors are not hooked up), but don't worry. nothing will happen.
-now take the car for a run and check if the vibrations are still there. if not, give me a PM and i will tell you, what the problem is.

I know this thread is ancient but I have a 1997 Acura RL with the rough idle issue and I’ve changed almost everything to no avail

The transmission mount is busted its a spider web mount you have to drop the exhaust to get it its expensive but the old one can be repaired with silicone if you read this reply and ill tell you how

I visually inspected the transmission mount and it didn’t look busted but I would still like to gain your knowledge to fix it when it does fail. Upon further inspection I noticed that the two stopper mounts are gone, It’s literally rubbing metal to metal. Could that be my rough idle problem?

 

[BabaFats]

heres the link to repairing a eng/trans moune

tons of vids out there on that
where ar the "stopper"mounts on the trans ?not sure what u mean the eng has 4 mounts and teh trans has that big one i mentioned

 

[dmiedema2010]

My car is having the same problem, according to the mechanic, it is the upper rear transmission mount.

The same vibration underneath the pedals once I accelerate.

Does anybody know where I can get this transmission mount cheaper than 160.00$... please reply--Thanks,

Rob
