To give alittle history, my 83 280zx non-turbo started cutting out while driving. I had this problem before with another car and replaced the ignition module. before the module was replaced the car sat up for a few months. After i replaced the module once the car would get to normal tempeture the car would start to get real slugish and start skipping around 3000 rpms.
since then i have replaced the TPS, rebuilt then replaced the Air Flow Meter, replaced fuel filter several times.
The car seemed to drive better for a few weeks but now is getting bad again.
Anyone have any ideas of things to test to find the problem?
