could having the ignition system cause me to throw a code? the code was P0352. ignition coil primary circuit #2 or something like that. i don't have the chilton book with me at the moment. anyways, i by-passed the msd today and left it un hooked. as of now, the check engine light went off and i have no codes. i didn't even have to reset the ecu. so i'm wondering, could it be my coil or the msd causing the check engine code? anyways, as long i pass emmissions, i'm strait.

Did you install the tach adapters? If you don't it will throw a code.

yeah, if i didn't install the tach adapter, then it wouldn't even work right. just like when you by-pass the msd ignition, you have to unhook the tach adapter. anyways, i have no check engine light as of now. so i can pass emmissions now. also, i can notice a difference without the msd hooked up. just a little less pep.

i just hooked up the dis 4 (same as dis 2 but you don't hook up channel 3 and 4) and got the check engine light. it runs great with out the tach adapter but it has the cel light on. i am hoping to pick up the adapter in a couple of days to fix the problem. anything else i should know about the ignition to fix the cel light problem.

Don't let the fact that the cel is off fool you, more than likely the cose is still in the computer. I was tolsd that if it's not something really major the cel will go off but the code remains on the ecu. I had an injector running rich and the light had gone out; the I still ran a diagnostic and the code was still there, even though I'd had no cel. You might wanna look into that.
