Thanks, I just ordered the round connector adapter. I sent a message to the seller and found out that some of the Chinese cables are missing a wire in them for ignition. He pointed me to one that will work, so we'll see how it goes when it gets here.

Any ideas on what I should start checking? Would the MAF cause issues over time? It seems like the misfires only happen after the car has been driven for awhile. It usually happens shortly after the second or third start while the car is warm.
