Hi please help,

 

just picked car up from garage today having an intake manifold change genuine vag manifold installed it’s also had new injectors and a new pvc and when I accelerate hard maybe going over 5000rpm epc light comes on pulls all the power back then let’s you have power till around 4000rpm until turned off and all resets and full power is back any ideas please this is happening everytime I get high up the Rev range had new spark plugs also would it be worth swapping all ignition coils out ??

 

thanks

I would take it back to the garage as clearly something has not been fitted or coded correctly. I would also stop using the power as it might cause more harm than good.

It might be they havent coded the injectors in correctly or anything like that but I would let the garage take a look and see if any fault codes have appeared.

Yes I am going to go back down tomorrow and see them they are an vw specialist had the new injectors put in because he thought it was a fault with them but was the intake manifold in the end so you defo think it’s something to do with the injectors because everything else runs absolutely spot on and it’s not all the time when I’m in high rpm just some times could it be a faulty ignition coil or a spark plug?

Sounds like a damaged ignition coil or the long rubber piece but sounds like a coil from when removing, surly you must be able to feel if the car is misfiring...

 

If you lay the power on quick, like plant your foot hard does the epc fault light come on & the car goes in limp mode until you pull over & restart.

Hi nope this problem only happens when revving over 5000rpm and epc light would come on taken it down to the garage again it showed a low oil pressure topped the oil up car revs all the way up now and pulls strong in every gear turns out that it has a sensor in the engine if the oil is low and you are sending the car high in the rpm auto throws Into epc topped oil up and no epc as of yet so hopefully problem is resolved can confirm no misfire with epc light on or off car ticks over beautiful

Hiya,

 

I have the exact same engine and problem, I had a code for faulty sensor - replaced the visible one but no difference. Have the 2 other sensors ready to be fitted so hopefully it fixes it.

 

How is yours running since? 

 

I appreciate this post is quite old but thought I'd ask anyway!

 

Thanks
