injectors might need cleaning?

[Ryoken]

just a quick one really , ive got a slight misfire at about , 2k, feels like its hesitating ,  (if i rest my foot on the accelerator),  i have noticed though the  little mpg gauge , at the time of the hesitation, that does fluctuate slightly ,  and then it feels like it changes gears .?
any whoo,  the car apart from this starts, fine , runs ok , isn't a slouch either, apart from the 15.8mpg,
so , Q is this , do you think it could be the injectors that needs a clean, cars done 156k  and most of the time its filled up with asda or sainsburies unleaded,  not super just normal fuel

ideas?
oh, ive put in new plugs , new coil tubes, cleaned maf, and throttle body.

Have you plugged in to see if any codes stored?

You can also buy a proper injector cleaner from BMW if you choose that route.

Petrol version is - 83 192 183 738

Cotswold BMW regularly offer it on eBay much cheaper than direct retail from a dealer 

I use the diesel version (83 19 2 296 922) in all my BMWs.

It's not transmission trouble is it? Mine had what I thought was a miss fire circa 2000rpm and 40-60mph. Hesitation was trans judder occasionally. Turned out the trans fluid was shot and never been replaced at 140k.

ive tried injector cleaner ,  didn't really do anything , however not tried BMW one
there are no codes stored , actually surprised at that.
i had ALL fluids changed about 9 months, front transfer box rear diff and gearbox,.
im hoping its not trans trouble, it seems like its at low speed ,. maybe 20 to 30 mph, i dont really get it at high speed ,
there is talk in the US about the torque converter being shot, or the  rubber doughnut on the prop?.
tbh, i can live with it , until  it gets that bad where something does go bang

Sounds like a car i had some time ago.
Started out like a very slight misfire but got worse and a year later it was like driving on the rumble strip but only coasting at around 60mph.
Turned out to be the lockup clutches in the torque converter. 

[Ryoken]

just what I need,  the potential of a gearbox removal to get a TC installed,  if it IS the TC , might as well just get a rebuilt gearbox installed
you know whats scary , I'm in way too much ££ wise , just to say sod it ,  its gone

[Alan Gunn]

I put 2 tubes of "DrTranny" in the box and the problem went away for a month or so but it did confirm the problem.
This is the stuff i put 2 in as you spill a lot.

I get a slight misfire every so often, I put in a can of this maybe twice a year, seems to sort it. https://www.amazon.co.uk/BG244-DIESEL-F ... B0062KYGZC

It's cheaper than she of the other options you are considering so may be worth it. as another poster said, Id get the codes read before I started spending money willy nilly

Hiya Smee
believe it or not , there arnt any codes stored !!!!!!
what an e53 with no codes. NEVER
I'm taking the shed off the road in a few weeks,  as I'm bringing my (deceased) dads car out of the garage , might as well use that than the X
then I can save some brass, and then I can play with the X without loosing 4 wheels

all I know ive had the car 3 years , its done 156k, and ive allways put sainsburies fuel in ,

well ,  that was an interesting afternoon,
decided to put in dr lube
parked car on kerb  (drivers side) so I wouldn't get any spillage  and id have room to put stuff in ,
nope wrong ,
ive lost about 1.5 liters of oil  I managed to capture all of it , but still  it tried to escape,
2 tubes successfully in gearbox, ive just got to wait till later and try to get them escapee liters back inside
no I thought  you filled the oil up till it  tricked out then  tightened up da plug,
wheres all this extra oil appeared from
oh , oil was changed maybe 6 months ago , now its a lovely shade of jukky brown ( like a normal oil change on an engine)
oh hum , ill wait till it cools down again ,  will do it tomorrow to try to get oil in

[henrym3]

Did you have the engine running when you took the filler plug off, like you do for the final top up?

[Ryoken]

shit , no , until later I didn't realise you had to do that, good job I didn't drive it ,  ill start the car up later and re put in the rest of it , , hold that thought , ive got some new tranny oil in the shed ill put new in instead of the old stuff
god I'm such a tool
