Hello all I have been experiencing many problems with my 8 lately and they all happened to day on my way home from the airport. I am so frustrated at the car and the incompetence of my dealership. I did some searching for several of these issues and didn't see much help so I might have missed it. If you guys could provide me with any help/insight it would be great. I plan to call up my dealership and give them a piece of my mind.

First off I drive an Auto 8 with 29K on it. I just had it serviced last week for its 30K maintenance and the car is still screwing up so there went 300 down the toilet.

Here are my issues sorry it is a repost I am just so upset right now I need to vent.

1. When I am driving my 8 down the freeway and driving in the manumatic mode when I get around 5500-6000 RPM I hear a horrible crunching noise coming from my car. It sounds like a car being crushed by a car cruncher. If I shift to 3rd it is fine it happens almost always around 5500-6000 RPM in second gear. It drives me crazy and scares me like I have a major problem.

2. I did a search on power loss and a lot of the threads seemed to reference a loss of HP. My power loss issue deals with my car completely shutting off. It happened 5 (yes 5) times on my way home today. If I am slowing down for traffic/stop light and I get below 5 MPH my car completely shuts off and dies. I then have to put my car in Park and restart the car. The startup always sounds rough and it is really frustrating. I live in the Washington DC area and traffic is always a problem and this same issue happened on 5 separate times while on my way home tonight. So less than 5 MPH and the car completely shut off. Talk about frustrating

3. Often when I am at a stop light/stop sign/or in traffic and have my brake depressed - after I let off the brake and coast my car shakes really bad. I mean it shakes horrible and I don't know why. It seems to happen a lot lately.

4. Also it seems like I am not getting the full HP from the car lately. When I used to hit the gas hard it would be quick and responsive now it is like there is a 1000 pound weight in the trunk. My performance has really gone down and it seems like the car is sluggish when I am accelerating.

As I mentioned I just took my car last weekend to have it serviced for its 30K and again I mentioned each of these problems to my dealership and each time I have gotten the typical "we can duplicate the problems when we test it" so I continue to get even more pissed off.

It is frustrating to have a great looking car with so many problems. And whats worse - I can't even get help with it.

I also use high octane gas only ususally from Texaco or Exxon.

So if you can please provide me with some info for my issues so I can go yell at my dealership it would be so awesome. Thanks

You really need to take the mech for a ride so YOU can reproduce the problem. But even that may not help if you're doomed by slacker mechanics. We had a car (Ford- ugh) once that the seatbelt warning would chime everytime we went around a right hand turn. Mechanic "couldn't reproduce it". Yea, ummm what did you do take all left-hand turns? So I took him for a ride and got a "Ding" on the very first turn. Some dealers just don't want to deal with s**t. Even after we demonstrated the problem and they put "their best guy on it", they still couldn't fix it. After a WEEK.
"Duhh we couldn't find the problem"
"You mean you're not going to fix it!?"
"Duhh we couldn't find the problem"
"Well, it's wires and buzzers, how hard could it be?"
"What do you want us to do?"
"Are you kidding me? Have you looked at the wiring diagram?"
"Our guy couldn't reproduce it after you left"
"You know what, I really don't want you touching my car after all. Go back to reading the comics. Stay away from 'The Jumble'. Don't hurt yourself."

Took it home and found the problem in about 20 minutes.

The problem sounds like a mix of transmission/ maf sensor problems. You might be able to really clean up the idle shutdown issues by cleaning the MAF(mass air flow) sensor. Also check the color on the dipstick of the tranny fluid. If its sh*t brown might be a good idea to change that as well.

thanks guys - I have printed out this thread and another motor mount thread to take with me to the new dealership tomorrow. I am hoping that they can figure out what the F is up with my car.

get your pcm calibrated or reflashed, I can't remember what they did but I know they sent the pcm to california. I can't find my service sheet to find out what they did specifically but it was one of those. The same thing used to happen to my AT 8. It used to drive me crazy too.

yep they need to be calling the tech line with your symptoms. whenthey do the tech line will tell them to send your pcm in for fixing. might also get a compression check.

also consider a clogged cat... that may be the 1000 lb weight in your trunk.

did this happen after your 30k maintaicne? If they cleaned your injectors, they might've fucked up putting them back on. causing the engine to misfire but i dunno. i hope you get this problem fixxed.

Just an update:

I dropped my car off to a dealer up here in the DC area this morning. I have used this dealership in the past when I ordered and installed my snow tires. I printed out this thread along with some discussing the motor mounts. The tech was very pleased about me bringing this information. I told him I wasn't trying to tell him how to do his job I just wanted to pass along some information. He was happy about me giving this info because the more info he can get about possible causes the better job he can do with finding the root cause.

He said it sounds from my description that there is something wrong with the cat and will check out the other problems. I'll keep you posted on whatever I find out good or bad.

Well I just got a call from the dealership and the master Rotary tech could not find any problems with the car

He said regarding issue #2 - where the car keeps cutting off that the battery was low so he charged it up.

He also said that if I drive my car at 6000 RPMs in second then I should know I will be burning the engine and the car. I called bull#### on this since the rev limiter is 7500 RPM so it should not burn up the engine.

I am going to leave work in about an hour and go out with the technician to see if I can duplicate the problems.

I told him I don't know how you could not find anything wrong with the car when I have had these problems I listed in the first post over and over again. This crap is really pissing me off.

I asked about the cat and he said he checked it and there was no problems.

what is the master rotary techs name?

also it could be a tranny issue. if the pcm doesnt get a proper signal from the Tranny Control Module(TCM) it doesnt know its supposed to idle. this could cause stalling. they should check the switches that tell the tcm/pcm what gear the tranny is in and when it goes to neutral. also speed sensors should be checked. did your car have the thermal damage recall work done?
