I have a 1991 Sunbird with a 4.3 Litre V6 with a cobra outdrive. Last year it started stalling when shifted into reverse. In forward it worked fine. The shift interupt switch was tested and works fine. According to a repair manual thru the process of illimination it points to the electronic interupt module. The engine has been tuned up with new pieces and idles very smooth and operates fine when in nuetrol. I have installed a new interupt module along with the new switch that came with it. Now it appears the switch is activating the module as it should when shifted into either forward or reverse- the only problem is it causes a delay of approx. 8 - 9 seconds during which the engine RPM's drop and runs very rough. After the 8 - 9 second delay the engine smooths out and seems to run perfect. A mechanic says he thinks it could be the shift cable. The cable operates the fingers and seems to operated the actual shift interupt switch as it should. When the shift interupt switch and module are disconnected the engine shifts into reverse or forward with no drop in RPM's and runs smoothly with no roughness. <br />Could the new interupt module be faulty or could it actually be the cable or something else?
