So I've been getting these like forever but has anyone found out the source of the problem and is it really something of concern? I've done a search and seen everything from replacing the clutch to yet another new factory flash that's supposed to take care of it although nothing really conclusive as the error says it's an ignition timing problem....hmmm. Anyway, as far as I can remember I've had new clutches put in and a new clutch master cylinder put in but can't recall when the P1320 code came on the first time. Everytime it comes, in a couple days, it would go away for a little bit and then it will come back again. I can't really tell if my EVO runs any different. The very first time this happened along with the rough idling, I found a vacuum hose that was disconnected; after reconnecting the vacuum hose, I've hadn't had this issue for some time but now it's back again. Any ideas or suggestions? Thanks in advanced.
