I'm not 14 why do I always have to say that... But anyways about the pushrods, that's incorrect. It doesn't matter if they go back in the same order at all. They just need to be matched up correctly.
Okay so then why is my engine running so rough? I guess everything I figured out was wrong so I'm starting over from scratch. |

That is not correct. They need to go back to either intake or exhaust valve depending on their length, but they do NOT have to go back to the exact same valve they came off of. We use hydraulic lifters with pre-load predetermined by the rocker pedestal and the pushrods should all be the same length (or close enough within tolerances) for either intake or exhaust, so it does not matter. As Malaclypse said 30 degrees of advance is common at certain times when the engine is running, so I don't think there's anything wrong with your timing either. The problem is somewhere else. edit: and yeah, why don't you go in the user CP and edit your personal details already so it shows your correct age?

so i changed my crank pulley and crank sensor(21x) that means i need a CASE relearn? the car runs fine until it gets fully warmed up and i let it sit for 10 mins at idle. thats what i dont get.

it's a 24x sensor, and yes you should get the case learn done. There is a very small chance that it won't need it, but 95% of the time if you change the crank pulley with the sensor ring in it, or change the pcm, it needs to be done. The engine will run without doing it yes... but it will run better after. Without the learn it defaults to base ignition timing. After the learn you should get a better idle and more low end engine response because it will be able to accurately read the crank position and adjust ignition timing for it under 3000rpm.

didn't want to start a new thread, but I wanted to ask if 23-25* of spark advance at idle(warmed up) is normal? My 04' gagt only has about 16* but these two have become very different machines. I went to get a crank relearn today, but the snap on tool needed to be updated or something else. Tried to purchase a dhp tuner but guy never emailed me back, so I'm still looking for a place that can do it
