Thank you! great help.

 

airmass wiring diagram fixed! next problem now is rpm wont go over 3000! haist!

 

Is that when driving? Probably rev limit if parked, to protect the car & trans.

 

both. when on idle and in running. also i heard a popping sound on the intake, but when i remove the TPS socket it will gone, also the brake will normalized from stiff to normal, but as soon as i plug it again the popping noise will be back and the brake will stiff again.

 

Air leak. Must be fixed. Many many threads you can read.

 

Sure sounds like a vacuum leak based on your description. The simplest, easiest and cheapest things to check first are:

-Brake booster hose. Not unusual to have those deteriorate
-IMT O-rings.
-PCV hose. If it is the smooth one, chances are it is split underneath. Newer style ribbed ones are much more robust.

There is a ton of information on all three of those issues.

Best thing to do is post the codes you have here as that would lead you in the best direction on where to start. If you have P0171 and/or P0174 start with what I mentioned above.

 

Thank you Brother!,I will look into that. by the way, i forgot to mention that i have already new brake booster, new brake vacuum hose, new ICV or PCV, new TPS, replaced all spark plugs, replaced three (under intake manifold)of the ignition coils, resealed the IMT o rings, resealed the intake manifold, resealed the PCV hose and still having this problem. Fortunately i am still looking forward to be a long time partner of this cat!
