Running problems

[devfuse]

Ok so where to start... i have had this problem before but it seems to just fix itself but not this time ! .
My 182 was running fine the other day filled it up with vpower and took it for a trashing on a private stretch of road 5th gear up a hill pulling about 120+ mph and the engine started to lose power and felt different (shuddering best way to explain it) stopped and turned the engine off checked to lamba clip under all felt good fired it back up and no problems felt prefect.
but
then on my way back home when i pushed the car from 60 to 80 it started doing the same so i pulled over and turned the car off again left it for 2 mins and started it up no difference same problem light flashing and wont go out. I left the car over night thought it might fix itself like it had before.. started it this morning same thing

i have changed both lamba sensors all four spark plugs, complete oil change and new oil filter still no luck ???

Anybody have any ideas think i am going to have to bite the bullet and take it to the dealer

i will upload a video also

Thanks.

Dodgy Injector? hard to tell from the vid but does it sound like its mis-firing?

It sounds like it's mis firing on one cylinder.....try and identify which cylinder is not firing correctly,and then take it from there....

Try coil pack then leads then start looking at injectors if they don't solve it

ops i forgot also changed the coil pack and leads still no difference

thanks for all the reply's

i think your right about it mis firing on one cylinder just hope its something simple and cheap to fix.

will let you know what the stealer says tomorrow

 

[DannyR]

99% it'll be an injector

 

[devfuse]

how much is a new injector ?

 

[DannyR]

2nd about £20-30 brand new £50-60

 

[fraz101]

Just disconnect each injector multi plug one at a time whilst its running and you'll know which cylinder isnt firing correctly mate

will give it a try thanks!

50-60 phew not to bad then, thanks for all your help guys

If u disconnect an injector and it runs even worse you'll know that cylinder is firing,if you disconnect and injector and it doesnt change how it runs,thats the faulty cylinder mate!

Keep us posted!!!

OK i love you !!! its the first injector! other 3 you unplug them and it get worse (did it one by one from the 4th to 1st)

but i don't know how to change it? You have to take fuel rail off to get to it i see looks like a nightmare todo

 

[DannyR]

Two 10mm bolts and pull hard but gently. Undo clip no tools needed, replace injector, put clip back in an replace rail

 

[fraz101]

It's not a difficult job,just disconnect the fuel pipe,undo the two 10mm injector rail retaining bolts,disconnect multi plugs and gently remove fuel rail (it will be tight) then once you have rail off,just take the metal injector retaining clip off the faulty injector and replace!

[devfuse]

Will give you all an update tomorrow after i have got the part and fitted it fingers crossed :approve:

 

[devfuse]

OK sorted was that and omg.. it must have been on the way out for abit because it is pulling hard now !! or its just all in my head.....

thanks guys

Could it be the MAP sensor?
