I just noticed my truck was "missing" the other day. It really didnt affect anything until yesterday. Now it sputters and the exhaust crackles. I know that its not the distributor. A friend told me it is most likely the spark plugs or the spark plug wires. I decided to go ahead and replace them, but I wasnt sure on the brand to get. I've heard good things about Bosch platinums, but then I've also heard bad things about them. Any suggestions or reccomendations would be helpful.
