964 Turbo problem
Hi - My '92 Turbo is having issues, hoping for some advice on where to start.* The car sat most of the winter, when I took it out a few weeks ago it ran great at first, but then on way home started losing power at lower RPM's, got better above 3k and made it home.* Has been getting worse since then, and now just died.* Gradual worsening of power loss until car just quit running.* Tried to start and tons of blue/grey smoke.* After sitting 5-10 min was able to start it but only drive a few hundred feet, then died again.* Same now at home - will start but only run few minutes and then die.* Recs on what I should be checking?* Fuel system - pump/distributer?* Other?
Thanks |

To start I would check that your I/C is sitting properly and that the gasket is in good condition between the I/C and the throttle body.

Great advise Anthony, After checking all the vacuum hoses and the turbo hoses. your warm up reg / fuel pressure reg could be going bad. Bad gas could be an issue too
