My engine turns off in idle and accelerating

Greetings to the community .... I have a problem with my Chevy Monza 98 (TBI), last week I had a problem with a hose of the antifreeze that recent Case the engine as if trying to stop, found that the output of the spark plug 2 was damaged (I no longer sent spark) I had to buy the original coil (700 varos), disconnect the battery for a good time to reset the computer, when the engine starts it was paired very beautiful but when accelerating it a little attempt to go out, need to pump the accelerator a little to prevent it from getting out. In idle ... try to go out. What can be the problem since the check Engine is never turned on.

Good afternoon, in those cars it is very common for the IAC valve to fail that regulates the acceleration in both idle and at the time of revolutionary, it would be worth checking your mechanic.

Greetings and that soon your car.

Thank you very much for the suggestion ... I just saw the message since because of the lack of self I had to modify my schedules.

I would check the oil because those cars with the warm -up tuersen the cylinder head and lose strength. Czech that can be there

Greetings to the community ... After not having time to check my car I can do normal yesterday. I found the problem in the gasoline pump? And the engine tended to go out, removed the sieve and the engine immediately matches it, take it to try and as if nothing had happened. How do you see it?
