I Have A 1998 Infiniti QX4 I Had No Problems With It But A Small Oil Leak From The Two Upper Gaskets So I Went To One Auto Shop About A Month A Go And They Changed It For Me When I Received The Car I Saw That The Idle RPM Was Too Low (Around 5000 As Opposed To Around 7000 Before I Gave Them The Car) So I Told Them About It They Did Some Tuning And It Was Ok The When Turned Off The Car And I Started It Again The Next Morning It Was Back At 5000 And After A While I Realised The When I Shift The Gear From 'P' To 'D' Or 'R' The RPM Doesn't Go Up And Down Like It Used To It Just Goes Down Below The 5000 Line And The Car Starts Shaking And The Same Happens When I Want To Steer The Car.But There Was Something Weird During The Past Month That Sometimes On 6 Random Days The Car Worked Just Fine. Can You Please Help Me Because Jelly Beans Are More Useful That The Car Mechanics Here.tc

valve cover gaskets? or camshaft seals?

if valve cover gaskets, i'd say they probably got a vacuum line messed up somewhere. If camshaft seals, still a chance for vacuum line or also, maybe they got the timing wrong? Good luck. Post some pictures of your Dubai machine!

I Don't Know But I Think They Replaced Both Here Are The Pics From Under The Hood Of My Car Displaying The Places Of The Gaskets That They Replaced. And I Tried To Check For The Vacuum Lines I Didn't Find Any Ones That Are Not In Place.And The Car Worked Ok For Some Days So If It Was One Of The Vacuum Lines The Car Wouldn't Work Ok At All Would It??Answering Buzzman Question It's Just A Bad Habbit That I Picked Up From My Ex She Used To Love Writing First Letters In Caps So Now It Just Makes Me Write Faster.tc[/B]

Can you please use smaller resolution on your pictures.

Your problem seems to be timing to me like fueler said.

Losen the distributor and try to adjust the timing (advance it a bit) and see if the RPM goes up again.

I Did A Diagnostic Check And It Came With IACV/AAC VLV Can This Be The Only Problem??
