hey guys, when im accelerating, the check engine light comes on, and at the same time the light comes on, my car does not run, the light doesnt stay on, just flashes, and every time it flashes the car acts like it looses spark.

so far i have:
replaced the cap,rotor, spark plug wires and plugs
cleaned the throttle plate, and the IAC
cleaned the MAF and a few other small things

the problem seems worse at low rpm, but is bad all of the way up the range, it also seems to get worse the longer i drive

im confused on this one, anyone got any suggestions or had this happen?

 

I suspect it is the ignition coil or coil pack.
