MAke SURE your plugs aint too loose or too tight.
usually I do it like this, hand torque it all the way to the end, then get the Plug socket out and give it an extra 1/2 circle turn.
my plugs work for 10K miles already
Lets not forget, You might want to reset the ECU, especially after those stuff has been changed.
and, misfire happens. rapid acceleration and deceleration might trigger it too.

but if you can feel that it *chokes*, something is not moving smoothly. at least now my engine never choke, all the way to 9 K baby !
What you can do is throw a bottle of GOOD complete fuel system cleaner like redline into your tank. And run your car HARD, rapid accelerate and decelerate around the rpm range.
it helped me, so it might help you.

Make sure that the connectors are fully seated on the plugs.
A full connection is one where the plug boot completely covers all of the ribs on the side of the plug.

I'm leaning towards the cables not being attached properly OR possibly being hooked in wrong. (simple error, could happen to anyone)
I know when I installed my Racing beat wires, those S.O.B's were pretty tough to get properly attached.
Good luck, hope it ends up being something simple

I told then to provide it in writing how my intake and exhaust blew the compression on my engine, and he said they don't have to, it's up to me to prove my parts didn't do it. So when I get my car back today I am gonna shove the Magnuson Moss Act up his ***.

Get this, so I picked up my car and the service manager said, "As far as what caused the problem, who knows but the fact that you have modded the car means you accept libility for anything that happens, it's in your warranty book." the warranty book says nothing NOTHING about aftermarket parts voiding the warranty. It only says somthing to the effect of, you may find parts that will fit your vehicle Mazda does not approved these parts and they will not be covered. the fine print disclaimer say the do not accept liability for any injury death or expenses that result from the installation of these parts. That right there says it has to proven that my parts caused the problem, but if they wanna play games I'm calling AEM and greddy today to see if I can get a letter from them stating thier parts do not adversly affect my engine. I wonder what they will say if I can prove my parts didn't do it.

hey, have you done a compression check (for real)? what are the numbers?
I know you say the dealer said you had no compression but that could be BS.
I wouldn't say your engine is dead until you have at least that much info in hand.
Have you confirmed X-times that you did re-wire the coils and plugs correctly? (coil side harnesses and plug wires)

The numbers are definatly low I had another dealer verify the compression, both rotors, numbers were almost identical, 6.3, 6.4, 6.7. somthing like that I don't have the paper in front of me.
Kane your right I fell like I have. Today I'm going back to the dealership to speak with the owner/gm, with a copy of the act, and just state 'hey, these are my rights you have to do this or we go to court. plain and simple.'

I agree the law is pretty clear where reponsibility lies.
But to answer your question. I have exhaust so it's always deep, but it wasn't any deeper than normal, she's never stalled, I was parked rev'ed it up and the light flashed 8-10 times then solid, she has run the same since I got her before the cel and after the cel came along, it feels the same. All I can say if I learned anything from this is if your taking it to the dealer, unless you have a mod friendly service manager, you need to put the stock parts in, it's not worth the hassle of being denied.
