Got a 99, with a repeating and intermittent P0300 & P0301 misfire code. After several trips to a local ( who I deem highly reliable) it's at the dealer. He wnted to change all 6 coils, I told him just do the #1 since that is the most frequent violator....and we'll see what happens. After doing some research on this forum and a few others, it appears that the 99's have a regular problem, and I've read from a few people that while a recall hasn't been issued, that Nissan is paying the fix for this problem in the cars that have the problem. Anybody have any experience with this???
