well your either losing spark or fuel since compression doesnt magically go away like that. module, coil, fuel pump can all be culprits.

Re: Breaking Up At High RPM's

i really hope its the module.....i just had the rear end and all to swap it for another one with all new parts and a LSD.......coil is pretty new, i think go with the oldest part first, the module........all i know is something is wrong, its running a little rough at idle to, and all this happened after it sat for 6 months
