Recommended Posts

Hi every one,

 

As title says, i have a very odd problem with my Jzx90 1jz.

I put new oil and filter on the car Friday, then put it up on jack stands to start putting coilovers in.

Fitted Tien Flex Coilovers, Rolled the Guards and went for a drive Sunday arvo.

 

Straight away i noticed something was wrong,

vacuum on idle was normally ~25Kpa

max boost on WOT was normally ~14Psi

 

Now it is...

vacuum ~19Kpa

max boost ~9Psi

 

Car is standard besides de Cat and 3" exhaust.

No boost controller at all.

No vacuum leaks.

Doesnt blow oily smoke.

No cooler pipe leaking.

 

Any other ideas??????

 

thanks Aiden

Stock boost is usually 9-12. Is the weather getting warmer where you are? colder air = more boost unregulated. I know in the winter i was hitting 14 and spiking to 15-16 but now that its warm again i barely see over 10-12

That wouldnt explain the low vacuum guys. Cam timing could've jumped. Did the spool point move at all? Feel sluggish?

just kidding. check timing and look at the wiring by the filter. the knock sensor clips are pretty flimsy. check for ecu codes too. and how much oil did you put in it?
