Just bought the car,has 130000 on it.test drove it ran decent,the next day went out to drive it,it was pooring rain,if that changes anything,it started to run and idle really rough and poping out the exaust,ran like that all the way back home.opti spark mabye? would plugs or wires do this?thanks keith
Yes these optispark systems had all sorts of problems in wet weather most of the time you could replace the cap portion and that would solve it but most of the time I would replace the whole thing including new plug wires, coil wire,and spark plugs .Due to the fact that you have to remove water pump to access opti spark
