New Typhoon owner with problems

[nejoe67]

I just bought a 93 typhoon and its only building 5lbs of boost, I thought these things made 15lbs. I get going in it and it seems like it wants to fly, but then it hits about 5lbs and falls on its face. can anyone help any sugjestions on what it could be

You have a big vac leak somewhere , or your turbo to i/c hose is loose . maybe even the i/c to throttle body connection .

You have a scan tool right?

No scan tool

Give your truck a full tune up and new vacuum lines. Then put it on a scan tool to make sure its not slowly grenading itself.

If you have a laptop, download this:

Then buy yourself and ALDL cable, and see what is going on if you do not find something obvious.

...or a fuel delivery problem ....or a knock problem.

These trucks pull boost when they sense knock.

Is that 5 lbs by the stock gauge? Those suck.My autometer says 15 in. vacuum stock gauge says whatever it wants to. It truly is all over the place. You could be overboosting and not know it.

I do still have the stock boost gauge, and I dont think it is shuting down because of knock motor sounds great.

Just because you can't hear knock, doesn't mean its not knocking. The ECM pulls timing and eventually boost when it hears knock through the knock sensor. You may not hear due the other engine noise and the firewall. If you can hear knock its really bad and you on the verge (if not already) of needing to replace the motor.
