i have an issue with my ignition...i think, but i just wanna make sure by asking. My car runs fine until i get the secondaries opened up, thats when my car will bog down and backfire. i took the plug wires of the front side plugs one at a time and then the back side and the front side seems like its firing slower than the back. the car smokes sometimes also and it didnt do that before this problem. Can someone help me diagnose this so i can fix it? Much appreciated.

Check the primary coil resistance. Should be 1 Ohm or less, if I remember correctly. Specs and method is in the FSM. Could also be vac line disconnected from the MAP sensor.

I apologize 94rx7. Most people who live out here have it listed in the location. I saw your location was orlando and figured you made a mistake of thinking the far east ment eastern US. I was definately being a bit rude. It is not often we get many technical questions in this section since most people post them in the 3rd gen tech section. Were you able to diagnose and fix the problem?

no i havent really had much time to look at it this week due to work. but by monday i should atleast have it diagnosed....hopefully. though i did check the map sensor so all i gotta do is check the coils and hopefully thats what is is. do think it could be something else "circuit theory"?

Is your car stock or modified lightly or heavily? A list of mods would help with figuring it out. I have had quite a few plug wires go bad or come into the shop bad. When you get into boost on the secondary turbo at what boost is the problem occuring? Could this be fuel cut/ overboosting? In regards to the plugs firing at different speeds that seems a bit odd and also could be due to faulty wires. If you have a spare set of plug wires available I would try swapping them.
If you do not have a spare set you could try re-arranging them in (as in trailing wires swapped to leading wires and leading to trailing etc.) Same order coil and plug order just change the wires around. I would think it is either the plug wires or some sort of fuel/boost cut.
Keep us updated and as I stated before I am sorry that I came off rude earlier.

ok so i finally got around to checking everything u guys recommonded and another thing i came to realize is that i dont have any spark comming out so what im guessing and gonna check is the ignitor. if anybody has any more suggestions please let me know, any help is greatly appreciated.

You have no spark at the coils or at the plugs? If you car is running then you definately have spark somewhere. How did you check your spark? I am still highly suspect of the plug wires. If you wanted to I can send you some parts to check your car with and if you fix the problem you can buy whichever part it was that needed replacing and send the others back to me.

Shoot me a pm if you are interested in that.
