NDN-Grand Prix Posted October 22, 2003 Report Posted October 22, 2003 Are all coils or control moduales the same on the w-body cars? I have a 95 gp 3100sfi, Quote
99RegalGS Posted October 22, 2003 Report Posted October 22, 2003 I think that the coils are the same but the control moduals are not. Quote
GPRACER Posted October 22, 2003 Report Posted October 22, 2003 1994-2002 3100-3400 sfi engines have the same coils and modules, My car is a '95 and I had 2 coils go bad at the same time. I got the whole bracket at a junk yard with coils and module from a 2001 Grand Am 3400. Just bolted the whole bracket on. Works fine. Quote
4spdz34 Posted October 23, 2003 Report Posted October 23, 2003 as long as the coils and modules are they same style they are all interchangable. u could use one from a 3.8 on a 2.8....makes no difference Quote
99RegalGS Posted October 23, 2003 Report Posted October 23, 2003 I thought that the 3800 modules were different because they used the "C3" ignition system. Quote
GPRACER Posted October 23, 2003 Report Posted October 23, 2003 I don't think you can interchange modules from different engine families. 2.8 and 3.1 would probably be the same. 3100/3400 are definately yhe same, 3800/3300 would probably be the same. In all applications mentioned above the coils can be interchanged Quote
