The replacement PTUs needed a small adapter harness to connect the replacement PTUs to the car's harness. That small adapter harness has given some people issues due to bad connections from age/time - coil packs not firing or randomly dropping out. Again -- not sure your model even has this PTU adapter harness but figured I'd mention (if you aren't sure post a pix of how your PTU connects to the car).
