Double Crank Start - MAF & Throttle Body Clean -Alfa Romeo 159 2.2 JTS

Sorry guys for the audio. Please turn on auto caption! Apparently my insta 360 X3 lost audio authorisation after firmware update. I will try to get it fix! Thank you very much

mine started on 2nd go when I bought it, the problem was the injectors, I just added an injector cleanner in a half filled gas tank and it fixed the problem. Regardless, I had to add that cleanner every 2 tanks so.. at last I had to remove and properly clean the injectors and the hole intake as you once did.

[@elgdisco]

That's great David! Keep it clean

that happened to mine every time I used 100RON gasoline. there is a tsb with new software to be flashed that completely solves the issue

[@elgdisco]

Hello, Thanks for watching! That does happen and I think the car is "thinking", what is this new fuel you are feeding me? LOL But I did realise one thing while replacing my water pump, the double crank or sometimes "coughing" while starting in the morning went away! What I did was that I needed to unplug all the lambda sensors and the Engine ECU while I work on it When everything was done and plugged back in, the engine fires up easily every morning since then. Maybe you can try it. Cheers!

Hi Elgim! I just did the same 2 weeks ago, massive difference in consumption and gasoline smell issue fixed.;)

[@elgdisco]

Good to hear. Small things makes a great difference!

[@DashCamSerbia]

@@davidBarrel What consumption did you have before and what do you have now? Mine does 12L/100km.

[@FoxOkinawa]

@@elgdisco do you notice any improvement on fuel consumption after the cleaning?

[@elgdisco]

It's the same, I do a lot of city driving so not much difference for me

[@DashCamSerbia]

Hey man. This issue can be caused by dirty injectors and/or dirty intake valves. Try the direct injection cleaner aditive for petrol engines (pour it in the almost empty fuel tank, then fill it up). Then drive it untill it is almost empty again. Remove the intake manifold and check the condition of the intake valves (carbon buildup). You can use carbon cleaner spray and nylon brushes to clean them (it takes a lot of time, it took me almost the whole day). But I did mine preventively, I did not have any symtoms.

[@elgdisco]

Thanks bro, I have done all those before and they were quite recent. Will clean them on the next interval. But the MAF and throttle body clean seems to have solved the problem. I can start on the first crank now!

[@DashCamSerbia]

@@elgdisco Great.

[@FoxOkinawa]

Thanks for another great video. Does this only happens in the morning? Have you tried double priming the fuel pressure? i.e. insert / remove the ignition key twice, before pressing the start button?

[@elgdisco]

Hello Fox, Yes, only in the morning cold start, the rest of the day is ok. The MAF and throttle body clean seems to have solved the problem! I can hear my fuel pump primed and stopped once it's ready so ain't really the problem. I have also checked my fuel pressure readings from the OBD2 which is also good.

[@FoxOkinawa]

@@elgdisco btw, what is the size of the 5-star torx? thanks.

[@elgdisco]

It's TTS25 & TTS20. The two ends are different. But I used the bigger end so it should be TTS25

[@FoxOkinawa]

@@elgdisco Thanks for the info!

[@davidBarrel]

One thing I did when I did this exact job was not connect the air pipe to the filter, just let it suck air unfiltered from the engine bay and drive the car at night for just 4 blocks to discover he intake sound, is u ni que

[@elgdisco]

LOL, yes. It does have good induction sound. Going for open pot filter?

[@DashCamSerbia]

Also, do you smell petrol inside the cabin? Because the fuel pump housing can crack, and that can cause the engine not to start the first time as well.

[@elgdisco]

Hello, Yes, I had a hairline crack on top of the fuel pump before. Changed it, but I didn't have the double crank issue.

[@pvathirali3533]

Hi, with the new maf, did u find any difference in acceleration or torque?

[@elgdisco]

Not really, everything is managed by the ECU for maximum efficiency. Fuel economy may improve.

[@snipermidou1]

Hello my freind you have a idea how i relarn the throttle body for my alfa 159 v6 3.2 q4 jts?

[@elgdisco]

Hello Sniper, Did you unplug your throttle body with the battery still connected? Did you change a new throttle body? One simple way is just to disconnect the battery for 10 to 15 minutes then reconnect again. It should "relearn" the new part that's installed. If you have watched my water pump videos, I realised that my car has no more double crank starts and it drives much better after I have removed the battery and lambda sensors for 3 days. It does "reset" the ECU and everything runs better for me. Thank you for watching and subscribing! Cheers!

@elgdisco hello elgdisco thank you for your answer
