you can have a lot of explaination about this :
1/check the ignition system (coil-igniter?)
2/check fuel system ( fuel filter-fuel pump-regulator ?)
3/check the map sensor ?

what injectors are you running?
when u say you blew up the engine earlier what happened?
If you are running stock ecu then check the MAP sensor. it may have a damaged vacuum tube or else map sensor is faulty.
You could also have damaged plug wires as ramses974 mentioned. one way of checking is to see at night if you can find any spark leaks. (Blue streaks of light seen somewhere along the ignition leads or distributor cup while on idle or revving engine)

INJECTORS: 450cc
I leaned my 4efte too muc the crank made sound and a piece was broken.
where is exactly a map sensor, left side of the throttle body or the right one?
