Evt issue - only after warm up sputtering and hesitating rpm between 1k to 1500k rpms

[WaelBdelhady]

Hello guys

 

please help 

Omg Finally I got the direct key

I have sputtering and rpm hesitation after only warm up between 1000 to 15000 rpm 

these results confirmed by driving long distance with every try just to confirm the results

vtc issue - the yellow marks in the pic 

1 - disconnected both sides = issue gone

2 - disconnected right side only = issue gone

3 - disconnected left side = issue gone

4 - plugged both sides = got the issue back

Really want to confirm before I waste more and more money

My oil pressure is warm idle between 8-10psi , 2000rpm is around 38 psi , cold start around 80 psi 

 

I am living here in dubai with weather temperature up to 43 degrees 

 

I know the gallery gaskets needs to replaced but for now ,This sputtering will be fixed after I replace this vtc or the oil pressure will be the main issue? , I know and saw in groups some guys their oil pressure that 8 psi and they don’t have this sputtering


if the replacement will fix , do I need to replace both sides full covers assembly or just the variable valve timing solenoid


is there any possibility of any other warn parts effecting the vtc functions like bad pcv valve or others
