hi guys this is my second opti i bought a $100 one from ebay dident work figured just siad what the heck ill try it so than i went to advance auto parts and put the 230 one starts with a c not sure of the name (sorry if that doesnt help)... but anyhow they both do the same thing the oringal one had... it gets contast spark from coil to opti (i pulled wire out of opti and put it to ground)... so i figured the coil and icm is fine.. so now i took one of the spark plugs out fo the opti and started cranking the car and it was a very very weak spark.... was like this .....spark...... spark. was no contast at all. so now my head is spining.. the opti is geting spark from coil but opti is not sending a strong spark out.. the one thing left is the opti harness.. can that be the problem?
