Newly Found Problem With My 33 Gtst

[Guilt-Toy]

No its not.

You sure about that ?

could it be that my standard fuel pressure regulator has failed because of the better flowing fuel pump?

and the tuner will find that out when he puts the pressure gauge on it.

are you running a ebc?

and is it working

yes i will leave it up to the tuner but id like to know also to problem solve for myself. narrow things down you know.

just want to know who has seen this sort of problem before or who has had it.

cheers

until 2 weeks ago i was missing 60 rwkws due to the ebc having no power feed to the solenoid.

so it looked like it was working when actually it wasnt.

the power feed to the solenoid also controls your idle up solenoid, so it can also effect your afr's

thats why i mentioned it

another thing to check also is that your intercooler is not leaking, do a pressure test to see might be loosing boost and not know it.

im not running any boost controller. i am making boost off an ajustable hks actuator.

Could be a few things but, most will give other symptoms.

A loss of compression will slice power off, to some degree this can happen without appearing a massive smoke fest. Worth a quick compression and leak down test just to check overall engine health. A range of possibillities there.

The cam timing can possibly be at fault if the belt is stretched. If the belt has been changed but, not the idler and tensioner then this is possible. The shift in cam timing can cause a dip.

Small intake leaks. Check the pipes and clamps.

Intake pipe sucking closed. $5 fix for that one.

[R33GOD]

come to think of it could it be a faulty o2 sensor?.. because when we installed the a/f ratio gauge we cut into the wiring

[R31Nismoid]

O2 doesnt affect power

[R33GOD]

ok... thought id ask, lol

[scheris]

Has the dyno been checked lately ? maybe it is reading differently. >;P

[R33GOD]

the dyno is fine.

car isnt pulling like it used to. i find out tomorow whats wrong with it anyways.

i needed to know what causes this problem so i can diagnose myself if it ever happens again
