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 gone2 - disconnected right side only = issue gone3 - disconnected left side = issue gone4 - plugged both sides = got the issue backReally want to confirm before I waste more and more moneyMy 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 sputteringif the replacement will fix , do I need to replace both sides full covers assembly or just the variable valve timing solenoidis there any possibility of any other warn parts effecting the vtc functions like bad pcv valve or others

Hello everybody Please help from z expert owners 🙏🙏 Rpm dropping/ stumbling at 1k and around 2000k Sorry for long topic 🙏🙏 I have an issue ongoing almost for one year now with my 350Z 2008 VQ35HR automatic 151000 Km 100% stock, which is the rpm is dropping / hesitating / stumbling just for one second at 1k RPM and around 1800 RPM (( only when it’s warmed with slow acceleration when starting to movie from signal or stop so I can feel it while I am driving And absolutely perfect when it’s cold just for first 5 to 10 mins driving )) without cel or any error codes . it’s Like the car about to switch off but it’s not , just need to press little harder gas to avoid the hesitation . This is happening while I am driving , P or N , so I don’t believe it’s transmission issue . No any lights or error codes at all Note oil pressure is cold start around 75 and after warming up around 10-12 , I know maybe gallery gasket needs replace too This issue gone twice before , both after I replace all parts above and no good First time : I went to mechanic who was working in Nissan dealer just trying to figure out , He just cleaned sensors and under the air intakes manifolds ( the black box on the engine) ,then put tap on the very little cracked piece in air intakes pipe and the problem totally solved , I kept asking The mechanic what is the problem was and he has no answer ( just by luck ). After few month The alternator gone and needed to be replaced, while replacing the battery has been disconnected for night , and I got the issue back when I received the car . Second time : after researching I decided to do exhaust valve control timing relearn which is keeping the RPM between 1800 - 2k for 20 seconds then the problem almost gone and not irritating me like before at all . Replaced Spark plugs, throttle bodies , cam shift sensors, maf cleaned and air filters . No coolant, oil leak outside the engine , compression test is fine as per Nissan dealer It’s fine to replace the gallery gaskets but I want to confirm that is the correct time . Now I confused , what I should check ?! -Gallery gaskets -variable exhaust valve, VVT -vacuum leak Really sorry and I appreciate any help or thoughts
