2.3-16 performance and power problem
 

hello
I have 2.3-16 v before 1 week I turned off my engine and everything ok
after 1 hour I turned on the engine too much slow
RPM is very difficult to go after 3
now I cant drive more than 90 km performance too much bad
I changed
1) new spark plugs
2) new fuel injectors
3) new fuel pump
4) new fuel filters
5) used fuel desaturation
6) clean and change fuel check
7)Ignition Coil
8) computers
9) fuel pump relay
10) over voltage relay
11) regulator
nothing happen

please what is the problem ?????????

IT SOUNDS LIKE IT YOU MAY HAVE JUMPED THE TIMING CHAIN. DOES IT IDLE? IF NOT WILL IT RUN IF YOU GIVE IT GAS? IF IT DOESN'T GO PASSED 3K RPM IT MAY BE LEANING OUT. FUEL DISTRIBUTORS ARE OLD AND THEY HAVE RUBBER SEALS LIKE ANYTHING ELSE MY NEED A REBUILT UNIT TO FIX PROBLEM WITHOUT SEEING THE CAR OR KNOWING MORE SYMPTOMS HARD TO TELL. WHERE YOU LOCATED?
