Surging when cold/first started
So i got everything running right again (thanks to you guys 
), even i think timing is close now, but i have a issue where the idle surges in park instantly when first started in the morning but goes away after maybe 10 seconds.. plus when i drive it somewhere and leave it in the parking lot for maybe 20 minutes go out and start it up again it won't surge anymore in park but when i put it in drive and start slowly driving you can feel the whole car jerking back and fourth for about 5 seconds then everything is normal.. feels similar to surging.. any ideas about that and what i should look at? Thanks again!
