Technical Help please!! Injection symbol won't go away
Bought the twin pack and I went to the petrol station use the entire 2 bottles and added about 8 litres of fuel, then went for a drive symbol kept showing but i'm guessing it doesn't work inmediately, I drove the car up to 50km, I hope it works man, thanks for everything, I will keep you posted!!.

You should rev it hard while driving. Go somewhere out of the city and cops and start changing gears at 6000 rpm at least.
Consequences of these products is that engine will run roughly. That is ECU adopting to new parameters.
If you experience sudden loss of power, then deffienetly is your coil pack faulty.

I have just bought the coil pack out of ebay, hopefully I get it by tuesday the soonest, once I do I will fit the new pack coil, and I will disconnect the battery for a reset, and then I will have a go, hopefully that will sort out my problem, I will let you know how do i get on, thank you!.:slayer:

No problem! I'm holding fingers crossed that it works.

People always seem to think redex and other fuel additives will stop the engine management light coming on. (Yes the engine management light). Even though the light looks like an injector it actually lights up should there be any problem with any of the sensors, timing, etc on the vehicle not just Injectors.
Like i said ring round for places that can diagnose your car so that you can get the error code print out.
The £8.99 for the useless fuel additives could of gone towards the diagnostic. Now its money down the toilet.
In regards to resetting the ECU you only need to disconnect the battery for a few hours, reconnect and then turn the engine on and let it idle for 5mins, not 30mins.
Could be coil pack but does the car mis-fire, run rough?

Well I have to try everything to try and sort it, but as I said previously I took the car for a check to the garage, then is when they changed the plugs, but then they told me it was the coil pack it needed changed, and afterwards i'd noticed a couple of red paint marks on the coil pack, however I have bought a coil pack now and once I get it I will install it, and then disconnect the battery for a reset, for 45 min and let it in idle for 5min, and hopefully it works this time, on regards to the mis-fire, well it runs fine I have no problems with it, it drives excellent, it's just that when the symbols stays there for a while once I stop the car and try to restart it struggles to get back on, I use to pump the gas pedal before till it started but today I have been restarting it without any gas, and the other thing is that it's using a lot of gas i'm guessing it is because it loses some power so I have to put more gas.

Why would the coil pack be bad then if the car runs fine. Your problem is starting the car once warm? I can only assume its the crank sensor. But a diagnostic would be your best bet.
once i get the new coil pack and try it, if i still get the symbol the next thing to do is to get a diagnose, but fingers crossed this works, cheers.
hi mateSymbols shows that smoething's wrong with injectors, coil or even ECU cannot determine proper ignition timing from Knock/MAF and/or crank-shaft position sensor.
You must not start your car with fully or slightly pressed gas pedal!!
Normally simbol must dissapear within 6 seconds.
Keep your old coil for the time being as first you have to check if your injectors are clogged or only partially clogged (where I recommend using double dose of STP injector cleaner- white bottle and minimum amount of gasoline in your tank), if this doesn't help, then you have to take your car to diagnostics first (about 15 euros, not more!!!) and if you need to clean the injectors, use ULTRASONIC system and nothing else.
BTW new coil doesn't cost more than 60 euros!
Cheers
isn't it too much two bootles of stp for the system with the minimum amount of gasoline? its written pour one bootle to full tank.
can we use as you described without any damage?
cheers

I have used following on fiat 1.6 16v:
- STP injector cleaner
- CPL (cheramic power liquid) Sport
- NOS Octane booster (3 grades plus)
Sometimes I was adding STP power booster, when I was not able to buy NOS.
And lets say that I was not having full tank of fuel every time, having all those products inside......:devil:
Regarding Crankshaft TDC sensor, that one is MECHANICAL and no adjustment can be done on it.
If the car missfires, it is not Crankshaft TDC sensor, but coil pack/injectors/fuel pump/fuel pressure regulator, of which latter is not most likely.
I have already said that after adding those products, if nothing happens, a diagnostics should be attended.
Still my money is on injectors and that ultrasonic cleaning should be perfomed on them.

i have this same problem i was told it was my thermostat sticking as my temp did not rise after half hour of driving is this correct?
Right so I bought the coil pack, got it today, but unfortunately i'm having one problem, the original coil pack numbers, start at the bottom right #1 bottom left #2 top left #3 top right #4, while the numbers in the coilpack i've received starts at top left #1 top right #2 bottom right #3 bottom left #4, and obviously with this differences ia am not able to change the leads as they do not stretch to the correspondent number from the new coil, do i ignore the numbers in the new coil pack?, and just connect the leads in the same order as the original?, don't know what to do!! :bang:

Connect the leads up as the old ones were.
But please stop wasting money on a guessing game, the light on means that the ECU HAS LOGGED a fault. Get it to somewhere who can read the code from the ECU and work from there.

This wrong. A failing crank sensor or damaged cable can and will cause missfires and running issues, particularly at higher revs.
The 12v has one injector, and the symptons imo do not match it failing. No amount of fuel additives is going to do anything, most fuel in the uk includes it anyway.
The fault is imo, TDC, TPS or MAP. But get the code read.

you CAN intechange cylinders 1&4 as well as 3&2. As the spark gets to those pair of cylinders at the same time.

1. all engines have one injector per cylinder....
2. if crankshaft sensor is faulty (only electrical wiring can be wrong), ECU shifts angle of ignition untill it gets (learns) what is ok and comparable with stored software.
3. engine can missfire even when ECU is in so called SAFE MODE - ECU resetting is required and red key.
4. I HAVE mentioned that engine will missfire it the ctankshaft sensor is faulty.
5. if the injectors are even partially clogged, fuel additives WILL help!
BTW, lets not c/p other people posts and crap on them then.
If you are reffering to my 1.6 16v engine and all those additives, just check my dyno results in members cars....
hi i have managed to install the coil pack although the numbers were in the wrong order i installed them in the originall order then i connected the battery switched the engine on and left it idle for 5 min but when i first turned the engine on it was really noisy but the second time i turned it on it started great there after i went to test drive it and the car was running smooth especially when changing gears eventually when i was doing over 40 the light came back on so i stopped the car tried to start the engine again and the same problem it struggled to start again so when i managed to start it i drove home and the light came back on again, when i got home and switched it off i turned it on again and it started with no problems straight away im putting the car through its mot tomorrow and gonna see what happens....
thanks for your great advice

1. all engines have one injector per cylinder....
No they don't. The 1.4 12v engine has ONE fuel injector, sitting above the throttle butterfly.
2. if crankshaft sensor is faulty (only electrical wiring can be wrong), ECU shifts angle of ignition untill it gets (learns) what is ok and comparable with stored software.
No it doesn't. If the sensor or cabling is faulty, as the frequency of the signal increases due to higher (it is a waveform) then it begins to destablise, sending erronous data to the ECU. This causes it to make incorrect timing calculations, meaning poor running.
3. engine can missfire even when ECU is in so called SAFE MODE - ECU resetting is required and red key.
The Red Key is for programming new slave/blue keys. It's not needed to reset anything. The ECU enters safe mode to help prevent engine damage. If the engine has a serious misfire and is still misfiring it in Safe Mode then there is something very amiss.
4. I HAVE mentioned that engine will missfire it the ctankshaft sensor is faulty.
Agreed.
5. if the injectors are even partially clogged, fuel additives WILL help!
As stated, there is one injector. IF the injector becomes clogged then yes cleaning it would help, but thats not what i think is wrong here.
BTW, lets not c/p other people posts and crap on them then.
I'm not sure what mean here? c/p = copy and paste? I just quoted it. I'm not crapping on you, i'm just trying to offer the correct advice to the poster.
