My car has absolutely no pick up all of a sudden and revs everytime I press the gas pedal. When I rev the car in neutral I hear almost no blowoff in the first turbo but the second turbo blows off loud and clear. I had a large hole in my intercooler pipe so I replaced it and it made no difference. My idle is steady and the clutch goes right into gear. What hose should I look for first that could possibly cause a leak this big??

Also forgot to mention, the car has been doing this lately but nowhere near as bad as now. First it started out overnight and would rev slightly and as the month has gone on it just got worse and worse. Then I installed a 3" downpipe and 2 days later I installed a 3" cat back exhaust. Before installing the exhaust the car still accelerated decent, it just revved. Right when I finished installing the exhaust I have absolutely no pickup at all and the revving is unbearable. Any ideas?? Clutch? Massive boost leak? Why would it get so bad right after the exhaust install? Im getting desperate here. Thanks in advance to anyone with any ideas for me.

Ok... you didnt really give very much good info but here are afew thoughts.


Based on your description you are still running twins, and on top of that you are now running a full 3" exhaust system + DP (and based on my assumptions of who you are, you probably have no fuel upgrades, or ECU, or... anything but loud exhaust)

1st thing --- there is a little screw that controls your idle, use the search button to find this, it is pretty easy to adjust and should help lower your idle RPM's

2nd --- your car not making any power, when you add a 3" exhaust you are reducing the amount of back pressure, which helps with low end torque. Since you are running such a free flowing exhaust (low back pressure), and you have no fuel upgrades, and probably a stock intercooler etc, your set up is not balanced.

3rd --- be more descriptive with your posts, because I am pretty clueless as to what your talking about.

Isnt it supposed to do that? Do you mean it revs on its own? That would be an intake leak.
The lack of power thing also sounds like a bit *** boost leak. You need to be looking for the leak somewhere between the throttle body and the intake ports, so probably one of the vacuum lines just after the throttle body popped off, and as big as the leak sounds its likely the PCV is disconnected.

The larger exhaust wont hurt the low end power on a turbo car, just make boost come on sooner. The optimum exhaust on any turbo car would be a down pipe straight out the side of the car. And in any car, N/A or turbo, back pressure is never a good thing. Its exhaust velocity that helps torque.

if you suspect the clutch put it in first and slow let of the clutch with no gas if it start to drop down as it hits the engaged point then its ok, If its starts picking up rpm i.e. from 800 to 900 or more so might be a start; if not try vac lines. Whats your oil psi?

You're an idiot. The rest of the world puts bolt-ons on their car w/o ECU and fuel mods. The reason why I have no midpipe is because I have no ECU so I dont get where you get off saying "based on your assumptions of me". Name someone on this site that did fuel mods and a standalone ECU before they even put on a power mod and I'd call you a liar. Having an exhaust wouldnt make my car rev in gear or have no pickup. You make no sense.

2nd- I think I gave a decent description of the problem, why would I be adjusting the idle when I specifically said that my idle is great. I mentioned that so people wouldnt assume its a vacuum leak. But you might be alittle slow on that.

And to everyone else that actually had something logical to say thank you. I'll check out by the throttlebody but I'm almost 100% sure its the clutch.

dont mean to be an *** but my car also revs when i press the gas pedal lol...im confident thats what its supposed to do :p
it also revs when its not in gear...because its turned on and thats what engines do...
sorry but your post dosent seem to clear to me either.

what does "the car revs nonstop when in no gear" mean?? to me that means it idles..?? my car revs nonstop when not in gear too..if it didnt it would be turned off.. care to explain?

do you mean when accelerating your car revs too much for the speed your traveling? meaning your clutch could be slipping?

is the problem when your moving or idleing?? its unclear?? You say your idle is steady, but you also say your car "revs nonstop when in no gear"?

please make your problem a bit clearer, does the rpm raise by itself? do you accelerate - your rpm;s increase but no real increase in speed or what?

i too was baffled by what you said, but it sounds like you have a boost leak, check the other pipes going to the intercooler. Especially the accordion style, cracks can be hard to see in there. Do you have a boost gauge? If not you should get one, it will make diagnosing problems much easier.

Put a boost gauge on it and also start looking for vacuum leaks.
