I just bought this vehicle and the lot I bought it from said the only thing wrong with it was the rough idling, he said it's probably because it needs a tune up, which boy it did.
So I changed the oil, plugs and air filter and the rough idle is only slightly better. The weird thing is after you drive it for a while the rough idle goes away instantly, sometimes it comes back. I had the codes pulled and all it says is misfire bank #1, which I guess it means cylinder 1, it also brings up faulty 02 sensor, I did not change the plug wires but oh my gosh were the old plugs bad! It is amazing it ran at all with those in it. But anyway the wires did not look bad. I just hope to god this is not a fuel injector problem. Any ideas would be great, thanks.
