Car revs up and tubro spools but wont hardly go?

[l3igl3ang]

yeah i noticed the other day that my car would'nt hard go even at 4000 rpms and tubro spooling the car wont go and the odd thing is it only done this 2 times on me so far. I did notice my clutch was out of hydro fluid so i found the leak it was under the dash so i think i fixed that and it has'nt did it sence would that cause the car to do that? also i have some major boost leaks which i need to fix as well would that maybe cause my car to do that.

i just done a 6bolt swap on a 1997 gst and the motor was freashly rebuilt also i have yet to set the base timeing on the CAS which im in the process of buying a data logger to set it sence i dont have a timeing light or a ecu ground out spot.

yes, That is whats causing the problem. Turbo spools up really loud but it doesnt pull or go anywhere.

 

[l3igl3ang]

i guess i need to get them fixed asap

 

[nfernotalon]

Yep...

also notice the car some times idles werid like it jumps from 100 to 1500 rpm back to 1000 then back to 1500 would a boost leak cause the car to do that?

Your boost leaks would definitely cause the hesitation you are experiencing. As far as the idle surge, it could be many things from your ISC to a simple vacuum line. Check over all the lines and test the ISC.

You said you fixed the leak under the dash, usually that ends up being a bad clutch master cylinder. I would check into replacing that if you experience any more leaks or clutch engagement problems.

You answered your own queston as to why it won't move. I'm assuming its throwing black smoke from the exhaust?
The idling problem can also be related to your boost leak. Fix your boost leaks before you start buying new sensors.

Anyone know what the diameter is of the 14b? Im gettin ready to buy the stuff to do a boost leak test

Boost leaks man.. You did a 6bolt swap, but didn't expect boost leaks to make the car fall flat on it's face?

but a 2.5 inch culper for the 14b its the same size as my 16g im using a 2.5 inch culper with a pipe in side that. then i put a tire valuve in that and it works great

When I made my boost leak tester I found the valve stem at Home Depot. Any hardware store should carry them.

 

[nfernotalon]

Thats funny I went to a local hardware store here and they didnt carry any, there is no home depot or lowes here but ill try Ace tomorrow..

 

[-TunedDSM-]

Wow that is odd, if Ace doesn't carry them (which they should) you can try any auto parts store such as Napa or Autozone. I am sure any tire shop like Discount Tire or Belle Tire should have them as well.
