car was driving fine when one time after i drove it, it started acting wierd, i think it maybe a missfire problem. it is running sluggish until u get over a certain speed, the check engine light is steadly blinking and has a sound like puttering coming from the muffler. i took it to a auto place to put it on a machine they said not to much about some intake thing. i took it to a mechanic to let them listen, they said the samething about the missfire. we changed the sparkplugs but its still doing the same things but only a little, can u tell me what it might be?
