Turbo help/ starting

[scorpio87m1]

Hey guys, I have a 95 GST, and I have not had any problems with it untill now. I dont know what going on but when i start to accelerate from first gear, the car jump a lot and feel like it want to stall or just turn off. Only when i accelerate at high rpm like 3500 it is fine. What care it be. I am worry about my babe.... o And when i took the intake off the check the turbo there was oil. Wgat does that mean.

You need to do the basic tests and report back. Boost leak being a big one, check plugs, wires. Oil is probably coming from the tube leading from the valve cover to the intake. Search pcv etc.

but if i was a boost leak wont it do the same thing whem i am backing up.

Your a brave man if your building boost in reverse haha. Your past posts you were doing things turbo related so do the boost leak test. Do you have a aftermarket guage that also shows vacuum? Check the plugs, its quick and easy while you get the parts to make a boost leak tester or wait for it to come in the mail.

o so u dont use the boost backing up? ok and the only way i can get the tester is online? i bought new plug could it be the wires. O yes i have notice when I was on the highway today I only got 8psi i usually go up to 12 then back down to ten. So could it be a leak for sure?

have you done the leak test yet? or are you waiting on it?, it sounds to me like boost leak might be the problem

o And when i took the intake off the check the turbo there was oil

what do you mean where was the oil, im assuming you mean when you took off the intake pipe right?

 

[scorpio87m1]

yea when i took off the intake there was oil. I just dont get it. It only happen when i start in first gear i have check everything i guess. But today when i push the gas really hard it jump alot. Like lag or smething but really bad. it feel like it something was trying to get in or out.

A lot of turbo lag, and oil in your turbo means that its time to upgrade to a new turbo. The boost spiking means boost leaks, so once you get the boost leak fixed than look into the whole turbo thing. Check your ic couplers and your tb for leaks since they are the favorite places for leaks.

Is your car a AT or a manual?

If it is in fact a manual and you had the clutch pushed all the way in and the car started jumping then it sounds more like your clutch is slipping and might be time for an upgrade!
but if the turbo is building boost and the and you have no turbo leaks (test as mentioned previous) it probably isnt your turbo!
Now the oil you see in your inlet of the turbo can be from several different things! (turbo or engine blow bye)
Now the easy way to test if you have blow bye is to remove the dipstick while the car is at idle and you have positive pressure coming out of it then that is the cause of the oil in your inlet as a turbo is designed to leak if it can not drain properly!

just my $.02
