hey guys i think i have a spider gear problem , i was just driving then i got into boost and all of a sudden my car was jerking and going crazy, then i shifted into second and the same thing happened but once i put it into 3rd it was ok . i think third is ok because there is not as much load on the gears as there is in 1st and 2nd . then trying to get up my drive way on the way home i put it in first and it did it all the way up the drive way. then i threw it and neutral and gave it a few revs to see if it would sound the same and it ended up sounding fine. so if you guys think it could be something else let me know and if its the spider gears can you tell me where i can get some and possibly where i can get some cnc machined gears for it thanks guys

i just thought that it might also be the map sensor so tell me what you think guys or it could be the coil pack
