D15B2 No power, stuttering bad.

Changed :

Spark plugs, wires

Fuel pump changed (Not new. Have not messured the pressure)

at first it was sutttering just a bit, but after a while it started to loose power and now i can barely start it.

Re: D15B2 No power, stuttering bad.

MAP sensors seems to be working fine, i had few of them, tried each one.
cylinder compression is decent.
i pulled injectors out, 3 are working fine and 1 was acting strange, but still working.
Can timing belt strech or something ? (That would explain the back firing, misfires)
Maybe i need to clean the intake manifold ?
Im running out of ideas.
