CEL because of coil pack??

[fastezz]

OK I keep getting check engine light probably every 500 miles when I am cruising on the freeway... I am hooking up my logger today as I got a new cable in the mail, so that will probably answer my question, but the reason I asked if it was the coil pack is because it make a random ticking noise when the motor is running and trust me I am not mistaking it for anything else, let me know what you think, im posotive I will have this figured out tommorow but I got bored and thought I would get some input, thanks.

You can get a CEL related to the coil pack.
How is it ticking? Is it a mechanical sound or an electrical sound?

Pull the CEL and let us know which show up. It's kind of stupid for us to speculate before you have the code.

change the plug wires...common problem

Well the two codes it had were code 12 for maf sensor, and cody 43 for the egr, which was unplugged probably from my head swap... ooops aw well, but non the less the ecu is saying my maf is bad, could it be from over running it, it goes up to 2200Hz some times I know over 1600 is bad which may explain my knock problem at only 15lbs. But the coil pack is an electronic sounds, just like when it hits TDC and it make that clicking noise it does that randomley when it running.

It's not from a high MAF count. Have you possibly started the car with it unplugged?
The normal max output from the datalogger is 1606Hz due to the way the logger variable is stored unless you have a chip with 2X MAF logging range. The MAF will go much higher untill it starts dropping counts but that doesn't cause a CEL.

Now that you know what the codes are, reset them and see if they come back.

i have to reset my ecu it seems every 500 miles because of CEL`s just like this one, I still dont understand why @ 12lbs now, I am getting knock, like 16-22?? I tryed to richen it up but I kept doing it and it just kept getting to the point where i would hit fuel cut.

Are the same codes (12 and 43) coming up each time you reset the ECU?
