Okay.. just cleaned out the air filter, I still don't see a difference. How much does a full tune up cost and what does it usually include?

OldNate

Yea, i have the opposite. At about 4000 rpms and floored, it barely gets faster. It basically takes 10 seconds 0-60

AndrewAZ

At 4k RPM is probably the end of your torque curve so it does not feel like you are accelerating fast.

If I remember right the old 3.2l v6 had peak TQ of 233lb from a tad over 2krpm all the way to 4,500rpm.

OldNate

well, the audi I was racing went 0-60 in 7.8. And it says here: http://en.wikipedia.org/wiki/Mercedes-Benz_W210

that mine goes 0-60 in 6.9 seconds. There are also many other sites that say 6.9 seconds. And I don't just loose to the audi, i get smoked by it lol.

OldNate

Hmm, but it still should move preety quick after 4500 rpm even though most of the torque is gone. Because 10 seconds 0-60 is just sad lol. What does a full tune up consist of and how much do they cost? What should I ask a shop for. Should I ask them individually for new spark plugs, air filter, etc.?

AndrewAZ

I had the same motor in my ML.. And in the basically 1klb heavier than the ML would do 0-60 in about 9 seconds. Taking 1k lbs off should put you in the mid 7's. Honestly I think the 0-60 rating for your car is just wrong..

I found on edmunds 1 article that says 0-60 for the wagon is 7.5 seconds.

On another review the car they have a 0-60 listed in 8.2 seconds with a 16.5 second 1/4 mile. Thats for the 221 hp 232lb tq 3.2V6 SOCH aka your motor. They list a curb weight of 3,868 lbs

With times all over the place from 6.9 seconds-8.2 seconds it seems crazy.. but again my best guess would say based on the power and the weight and having driven 2 cars with this motor you are looking at mid 7's.

As for spark plugs you should easily be abel to do this yourself. Along with the filter that should be very simple take off 4 clips put a new one in. If you cleaned your MAF sensor the spark plugs and filter should be a walk in the park.

Just for the heck of it I put the E320 data into a drag time calculator and its saying you should run a 15 second 1/4 mile.

I also found a 0-60 calculator. It says the power to weight ratio is .058 with an estimated 0-60 mph time in 7.58 seconds.

I ran my BMW 328i in the same calculator for 0-60 and it came out with 6.76 which is close to the BMW rated 6.9 which manufacture rating is usually very conservative.

I also ran my old car which was an M3 in the calculator and it was dead on for manufacture rating. I also ran my old ML in the calculator again dead on.

You also need to take into consideration the age of your ride compared to one a couple years old and if your constantly racing or ******* it out there is wear and tear.

I don't think it's age of the motor. Nate has something we need CSI to diagnose. Power loss at 4k RPM and above (and it is power loss) usually means a restriction, so it may be air in, air out, or fuel in. Fuel in may be a weak fuel pump. Air in could be a blocked intake. Air out could be Eddie Murphy stuffing a banana in your tailpipe (sorry, old movie reference)

Anybody want to expand on this?

Z06EATER

dude it sounds like u have a weak block, trying making sure all your spark plugs are firing

OldNate

Thanks Z06. Tomorrow i'm going into mercedes and having all of my spark plugs changed along with new brake pads. Hopefully, that is the problem and all will be resolved. I will give feedback within the next 2 days, thank you all once again.

OldNate

Okay, I talked to Mercedes. The initiall diagnose was correct. They told me that the spark plugs were fine, but the MAF went bad. I decided that I was just going to install one myself. I'll let you guys know once I get the new MAF bought and installed.

OldNate

Problem fixed with new MAF!

Does anyone know if the HP and tourque is rated by Mercedes at the real wheel, or at the flywheel? Also, my stock '00 E320 is the fastest E I've ever owned - had a 90, 94, 95, 97 and now '00 (between my wife and I...). I was test driving a '87 944 Turbo the other night, w/5-sp, and was very disapointed

roaks

there's more - I actually asked the dealer selling the Porsche if he had left the emergency brake on or something. I told him my 320 would leave the 955 in the dust. He got really mad and asked me if I had the title to my car. I should've raced the guy for pink slips.

roaks

I do have a question though - maybe someone has else has experienced it.... Most of the time, my E starts normally. Every once in a while though, it won't start up. It never happens if the car has sat long enough to cool down completely - and I can't say it is directly related to being at normal operating temps. When I turn the key, the starter always engages, and turns the motor. Just every once in a while, usually in embarassing locations, it won't start. I have no indicator lights coming on either. Any ideas?

Flywheel (the real flywheel, lol)

The logic I've read is that ground ratings open the manufacturer up to claims if someone gets a dyno reading that is at all lower than stated. Then again, gas mileage claims are rarely true and they get away with that.

However, AMG ratings are known to be understated for insurance reasons. Perhaps the 320 has a bit more power than advertised.

j944

The stock 951 only put out 220 ponies. I had one years ago(hence the j944) and be it a fast ride take in account the age and turbo motor being worn out.
They handle like on rails though!

C280 Sport

All I know is that my E320 has 91k on it and I timed 0-60mph just over 7seconds.

saintz

Sounds like your battery may be getting old. When was it last replaced?

h0rn3t920

I agree. The 420 does it in the mid 6's.

Performance: Until the introduction of the E55 AMG sedan in 1999, the E430 was the most powerful W210 Mercedes E-Class sedan in production. Its 4.3 liter V-8 engine cranks out 275 horsepower and 295 ft-lbs of torque over a plateau of 3000-4000 RPM, giving it a 0-60 MPH time of 6.2 seconds and a top speed well above its electronically limited speed of 130 miles per hour.

So if the E430 has a 0-60 of 6.2 then the E320 has got to be slower...

It's the combination of the green paint and the blue/ purple hand that is causing you to run so slow.

Try replacing the TPS sensor at the top back of your motor and also check the status of your battery. It may not start at times if the battery is not fully charged or the TPS is faulty. I have been told by the parts counter at MB that the gell battery (large black one found in most wagons) can last 6-9 years and the standard battery 4-6 years before needing replacement. My TPS went bad last year at the Pittsburgh Vintage Grand Prix as we were leaving on Sunday. The tech from Bobby Rahal MB came over and diagnosed it and Monday morning it was replaced and problem solved. They are 30-40$ I believe and easy to replace DIY. Just one bolt and plug and play with no adjustment. Try that and see what it does for you.

I know the Brabus tuned V6 motor is different by pistons, stroke and cams, however I hit the speed governor at 6500rpm and it pulls hard right to the limiter. It does feel quicker than 7.8 to 60. It was quicker still using a smaller diameter wheel than the 18s it came with due to unsprung weight difference. Not sure of actual time though. 1st gear goes past in a blink. The first gear ratio must be pretty short. It is the same tranny, 722.6, for all the motor applications and it is slow to shift by comparison to newer models. The rear axle ratio in the wagon is 3.07 versus, I believe, 2.82 for all the sedans. That is according to the MB sales brochure for 2002 model year. The Brabus models used the same ratios.

The answer is in the owner manual: when the motor hasn't cooled down, it may not start at thefirst time. Then you press gently the gas pedal and it`s done...
