idle

I'm trying to diagnose a bad idle on my c230k, and hoping someone can point me in the right direction. Here is what I've discovered so far; Idle is bad when completely cold when warm its not perfectly smooth, but far better than when cold I've cleaned the MAF, and tried running with it...

As title ..... I have a w210 240 v6 which has a slight mis-fire on idle and very low revs, I have cleaned the maf sensor with zero result (so .. maybe a faulty maf??) next up will be plugs and plug lead testing along with finding any potential air leaks. What I have also noticed is the gear...

Hi all, any sugestions as in why my 08 vito is pushing white smoke while idle? As soon as i start driving after 2/300 yards it stops, but while idle again it's back to the same thing, doesn't burn oil(i checked), still has power, no water missing, no dash warnings, not even temporary loss of...

Hello all :thumb:, a newbie here to this forum Need a little guidence towards sorting out a rough idle issue i have, tho its not really that rough. Symptoms... ..cold/warm/park/drive or neutral i have a small amount of idle 'play' or 'hunting' :p. ..on start-up every 1 out of 10 times...

Hi guys new here.. Just bought an w211 e55 and getting used to the car. Something im concerned about is when i start the car . The car Kind of slightly shakes like a rough idle but not sure if they all do this. Checked all the brwather hoses and a scan brings up no codes Spoke to...

Hi guys, First time posting here but will share my (little) knowledge where I can for issues people are experiencing. SO...... Initially the code thrown up was reading a fault in the MAF sensor. So 80 odd quid later, new one goes in and doesn't solve the problem. Turned out to be the...

Hi, this problem has started occurring recently. If i drive from my house and then im stopped at nearby traffic lights for a minute or 2, the engine will start shaking or juddering very badly. Seems to happen only when engine is cold Normal driving seems ok. I took it to local mechanic, he...

Hi, newbie of sorts here. I've looked all over, but can't find a solid answer. I've had the dreaded ABS/BAS/ESP problem, and replaced the brake switch to no avail. I then came across several suggestions that the fan in the ECU box (behind the brake hydraulic control block) might be broken or...

Hi folks I have an ML280CDI in the Dominican Republic. I'm a Brit expat living over here. The Merc dealers are few and far between so I prefer to do most of my own maintenance, as I don't trust most Dominican mechanics. I'm fairly handy at turning a spanner, but I think I need some advice...

Evenin' all. I've just been to see a 1991 R129 SL500 I'm interested in, and it has (among others) an idling issue. The engine idled normally at first, but then rose to idle at 1500, then 1700, rpm. If I manually blipped the linkage at the rear above the engine, then held it against the stop, it...

Hello, Im A Noob First Time Poster And Long Time Reader, With My 3rd Merc That Needs Some Help (unlike the others w202 and w124) Foreign By Nature So My English Has To Be Excused. Thank You For Your Understanding And For Forgiveness If Ive Posted This Somewhere I Shouldnt. :ban...

Having recently replaced the alternator, water pump and a/c condenser plus an MOT pass without any problems last week I was looking forward to a few months trouble free driving in the C320. However, over the last couple of days the idle has become a little low and unstable (no stalling)...

An intermittent engine knock at idle. What could this be? Thanks

Thinking (merely a gleam at present) about a turbocharged OM606 into a W124 estate. Much as I love the 300 multivalve non-turbo W124, I find it needs more torque, a five speed auto and a less frenetic rear diff ratio to make it a really relaxing car. First option - fit turbo in the manner of...

Hi All, I have a C270 CDI est with 90k. The idle speed tends to hang around at 600rpm is this right?[ATTACH]51125 What should it be? thanks.

Hi my w140 s320 has an issue when idling. The engine idle seems to be a bit unstable-surging. Ive put new plugs leads & coils on. It runs way better than before but this surging issue seems to still be there. Cleanes maf no difference. On other forums people have menstioned ovp regulator/crank...

Can any member recommend a workshop in the Manchester area that has expertise on these old Mercs. Most garages seem to be more familiar with modern cars and if it does not have a computer they are stumped. Thanks

Hi folks, Rite so just bought my first mercedes it's a w210 E320 cdi. I bought it with what I could only describe as a fan belt squeal but now the car idles bad every now an again. Fan belt squeal at idle but a slight rev an the noise disappears Drops rev at idle in gear or out of gear, if...

Had a G55 for 3 months now, engine pulls nicely on WOT, but on idle its a little bit rough, almost as though its missing every now and then. It also bogs down a little on part throttle and the gearbox doesn't seem to know what to do on part throttle. Fuel consumption is also terrible (getting...

I I have a ML 270cdi and it I idles terrible. Just moving around from 700rmp to 800rpm.like it doesn't want to run. Also it feels like it's going to conk out sometimes. It's an automatic 2004 done 125k miles full service history. It's only started doing this. Otherwise has been perfect for me...
