Either one of your valves isn't reconnected/reassembled properly or something else came apart . . . the procedures below will help you locate the leak which is a useful place to start.

Looking under the front bumper there is an intake air line that has two rubber couplers - one on either end. I'd check those as they are attached with simple hose clamps that can easily come off. Of course check your air filter box - it's remarkably easy to put it back together slightly out of kilter - and you'll lose your boost there too. If you are daring and have a friend you trust dearly to "drive":

1: Chock the backside of the rear wheels with real wheel chocks.
2: Set ebrake firmly.
3: Open the hood and start the car.
4: Put into reverse and "load" the engine by applying some throttle, some clutch, and as much brake as possible. The car should not move. The load should jump up your boost.
5: At the same time as #4, somebody should inspect under the hood for escaping boost. It should be quite obvious.

Worst case diagnosis/cost scenario? front underbelly damage,hit 1' tall stake in ground. hissing sound ~5 sec & a/c fluid leaked by radiator gills. a/c blows warm air.


the damage will be a punctured condenser for the ac system
the green oil is the compressor oil that is circulated with the gas
you will not see the gas as it evaporates as soon as it hits the air. Best have an accredited ac specialist shop replace the condenser and any other damaged pipe work

87 thunderbird turbo coupe misfire from idle until 3g then hitting boost n runs smooth


check that the turbo is actually working at the lower rpms.check to see if it is a variable vane turbo where the vanes for the turbine wheel can be altered to produce boost at lower rpms. The vanes are controlled by a actuator on the turbo and is controlled by a vacuum hose controlled by the ECM. The misfiring may be actually over fuelling ( mixture too rich as the boost is too low for the mixture)

Audi TT 225 aircon condenser slight leaking from top.


Hi Andy
As Roger said take it to an AC specialist and have it checked, it will probably need re-gassing. AC gas leaks show up as an oily substance.

Turbo / Boost Issues


Sounds like a faulty boost pressure sensor or waste gate. I would check the waste gate first. Sounds like it is opening to soon and letting the boost out, than regaining again.

hi sounds like your high revving has accidenetaly pushed off one of the turbo boost pipes or possibly even split a hose causing it to leak boost pressure get a freind to lightly rev the engine
so you can hear where its coming from if youve split the hose you should find it quite quickly with the bonnet up, or if need be get car up on axle stands and listen for it underneath, for a temporary fix and i mean temporarary wrap the split with gaffer tape or duct tape will restore your boost but not if you give it max revs good luck
