Alright, i really need help on this one cause im not sure what to do.

I just got back from the mechanic and fixed most of the minor things.. break line ect.. cleaned injectors and TB, the car runned fine.. the next day i tryed atleast 6 times to start it.. it started then died.. then the 6th it started well.. then i was driving and went on the highway then i was looking at the speedometer.. and i could not pass 60 km hour.. even pressing on the gas to the floor then i decided to go in a street and stopped the car but it stalled.. then it din't start anymore it just cranked. I have no clue why, ive changed the ECM.. sparkplugs..fuel goes to the injectors.. there's fire.. im really clueless.. please help me.

thanks guys.

Any codes set in the ECM?

Hey! Try tapping the Mass Air Flow sensor with a screw driver or a wrench. When the sensor starts to fail, it tends to work intermittenly. It will run fine, then like crap. If you tap the sensor, often it will level out while tapping it. Good Luck.

Sounds like a plugged converter to me.
