hello i just bought this 03 Z supercharged,and im having some problems..
to start when im in 4th gear the slip start to blink and cut the engine power with no aparent reason.i saw on other thread that this can be caused by different tire size..i have some SSR rims with F 245-45-18 R 265-35-18,that the previous owner had on it,can the Front tire be the problem?? the front tire actually looks pretty tall and the back looks small... If i disconnect the VDC it works ok..

2nd..i test the car today and after 30miles the VDC,SLIP,Brake,ABS lights came on,but after i turn off the car and restart it goes away,again can this be caused by the tires?? i checked the fluid level and is ok on the MAX mark

3rd. im having the intermitent window rolling down when shutting the door,i got the reset TSB but i have problem finding the reset button,i removed the door panel and saw that behind the panel is a steel panel,do i need to remove this to get access to the button?

4th. The Oil pressure gauge is kinda stuck,when i open the swith to the ON position the level goes to the MAX and stay there no matter if i turn the engine on..i was told that this can be caused by the oil level sensor that went south...how can i fix this?

Please Help A Newb on this Thanks

245/40/18 - 275/40/18 will stop the power loss/vdc problems.

window rolling down is going to be a reaccuring problem. Just take it for a new one especially if they will do it under warranty.

1 and 2 are caused by your tires being the wrong sizes. 245/40/18 and 275/40/18 are more ideal. Your front is too tall and rear is too short. The car thinks youre slipping the rears at high speeds so it cuts the power.

The dash lights go on because of the wrong size tires, the ecu doesnt know what to think.

4 bad oil pressure sending unit. Replace it and you should be fine.

3 i live with it, not worth my hassles to fix it (out of warranty)

I have a pair of 265-35-18 Nitto's Pretty new that i planned to put on the rear..im going tommorow to pick up some new fronts.so 245-40 should be fine..what about the rear one's with my nittos..also im new to FI cars..my car when going WOT the boost is constantly @5 psi but once it past the 5k it goes to 7psi.is this normal?? also my car has this mods and im getting a prrety decent deal for some aftermarkets

the car has

Vortech Charger
Borla Cat Back Exhaust No headers
Jim Wolf Clutch And Flywheel.

now a friend is selling me some STRUP or STRUT headers,Greedy E MANAGE BRAND NEW for 500 does this sounds fair??

I also Noticed that one of the Valve Cover gasket are leaking and im getting oil on the headers causing this smoke when i drive the car hard..So i need new Valve cover gaskets..are they the same of the Murano,Altima Etc??

Those are good for the front , but not tall enought for the rear.

Please don't waste your money on a Greddy E manage. Probaly the worst piggyback you could get for the Z.

the dash lights may be caused by the wrong size tires. ., but recently i had an 05 altima in here with some rims that had the same dash lights. Ended up being a TSB on the RR abs sensor, and then even bigger problems her RR solenoid wasn't working with in the damn ABS Actuator (module). 1212.91 for that sucker. .and the abs sensor was 174.00. .sucked for her but i fixed it and solved the problem!!!

b4 you go changing tires n rims n what not. .hows about you take it somewhere that has a MODIS or a nice scanning tool that can access ABS .and get a CODE. .even though your CEL isn't on. .the ABS has it's own set of CODES!!!!
