I have a 88gt with mass air conversion and there is no check engine light but the other day when I started my car the dummy lights on the right of the steering column would flash until I gave it a little gas then go away when I drive. Only does it every now and then. I have an o/r h pipe with no cats(and of course no o2 sensors), is this the problem? I know it could be lots of things but if anyone has had the same thing happen please let me know what caused yours to do this. Thanks
