Fuel Injector Cleaner

[Clint_M]

Hi, im living in the UK and i just wondered where i could get hold of some fuel injector cleaner?

Mine sound very clogged, i get a tapping noise when i accelerate which i have researched and it looks like its either the hydraulic lifters or the fuel injectors, makes me think its the injectors because the noise is only there when i actualy press the accelerator, if i take my foot off but the car is at high revs there is no noise.

Also i have no idea about this one but if i have my AC on, the car idles a little higher than usual, if i turn it off, the car idle sometimes drops low down then will stabilise after about 2-3 minutes of driving, got no idea what that could be but its not too bad yet, was wondering if it is possibly related.

Anyway, when i get hold of the injector cleaner, how do i run it through my car? do i run the car low on fuel, take it for a run then fill up with petrol normally?

Any help would be appreciated!

cheers

check ur 02 sensor and clean ur icv for the rev problem, usually fixes it, fuel set it a product in australia which cleans out all water liquid in the cars fuel tank proberly do the trick

[Clint_M]

Ive cleaned the ICV, not checked O2 sensor though so will do this first.

Whats the product called thats for sale in Oz?

Fuel Set, search for liquidengineering and read about it

What engine do you have there Clint?

I am assuming you have the E36.......not the E36 compact? It makes a big difference to the engine type.

ps. You sure its not just a bit of "pinking" your getting there on acceleration under load? (is it a "ticking or a tinkling" ? )

[Clint_M]

Yes your correct, its an E36 M40 318i 1993.

Im not sure if it is 'pinking' i would definatley describe it as a ticking rather than a 'pink' and it only happens when i am accelerating. When i release the accelerator pedal it pretty much goes even if revs are high 3000+.

Ive not really paid attention to it much until i realised after about 4 months of driving it was starting to bug me a little bit

I also have another problem with it but my independant specialist i took it too said hed never heard of or seen the problem before.

The clutch pedal seems to vibrate so excessivly that it causes a funny rapid ticking noise behind the dashboard, which sounds like a cable being vibrated against a piece of plastic very very quickly, so it sounds almost like a drone noise.

I have found a quick fix for this, although its not very comfortable, i have to keep my foot covering the clutch pedal to stop it from vibrating, then the noise never happens, altho all the vibrations go up my leg and i doubt its good for my joints :P.

Clint, what you describe certainly sounds like it could be pinking, it might be worth just to find out next time you fill up pick somewhere that sells super unleaded, and put a tank of that in, if it goes away or diminishes you might get a better clue.

As to the clutch vibration?

Although I am sure I read in here somebody was complaining of a ticking noise from behind the dash/IP.have a quick search, see what pops up in here.

Best regards David

Ok, theres a BP near me that does BP ultimate, ive tried some of it before but only in small quantitys, quite possibly mixed with regular unleaded.

If it diminishes with the higher grade fuel, what would that indicate? that i need to keep paying 97.9pence a litre ?

Yeah the clutch vibrating stumped the BMW garage too, and he said to figure it out would take 11 hours labour to remove the front inside the car + take a look, and might not be able to fix it.

Yeah there was me and one other guy who questioned the ticking noise from behind the dash, although that was before i figured out it was just very intense clutch vibration, i have no idea why the clutch vibrates, is it even supposed to?%%

I have used Chevron Techron. Excellent product. My car now runs smoothly and my MPG has increased. Just my 2 cents.

No, but as I said, it would give you an indication whether its combustion problems (a bit coked up) or top end wear (followers or injectors).

Vibration? what about propshaft? balanced?

Best regards David

ps. I had a Jag once that suddenly developed a strange humming and slight vibration, turns out it threw one of the small welded on balance plates from the propshaft!

[Clint_M]

im unsure regarding the propshaft, maybe ill get it looked into at some point, ill give the car a run on premium fuel for a bit, see what happens.

if it doesnt help ill try the injector cleaner just to see, if that fails, guess ill live with it until i offload this one p/x for a 328i sport! :P

thanks for the replys guys, much appreciated
