i just put an msd box and coil on my car with the msd harness and now i get a code 42 (Ignition Control (IC) circuit (shorted or grounded circuit)) how do i go about fixing this?

 

and i should probably add that i bought the stuff used and it came with the icm, so i changed all of this. could the icm be bad?

 

nevermind guys i fixed it. i got to researching via a search and reading other peoples post and i kept thinking to myself, "get off your lazy butt and go see what is wrong with your car". then it hit me, what a hipocrit (sp?) im sitting here asking online rather than some parts swapping (with parts i already had) so i did some swapping and it turned out to be a bad icm.

thanks for all the potential help though

 

I'm glad we could help.

 

yeah, your welcome, lol

 

ahh you guys are too much lol

 

mine threw that code last week along with another maf code (36 i think). if was from the engine getting water sprayed on it. deleted them after they popped up a couple times and no problem since.
