out of nowhere today my silverado started acting up. its idling at like 1000, the service engine light popped on, when i put it in drive from park it slams in gear, shifting to second is extremely hard, makes you move forward on the seat, shifting into 3rd gear is a pain, you have to ride out the rpm's and if youre coasting at 3ish normally it would shift but it wont for some reason or if youre going a decent speed and let off the gas it would shift into 3rd but now it wont. only if your in the high rpms and still accelerating will it shift. it slipped when it downshifts and if you push the gas without feathering the rpms dip and it acts like its going to stall. although i think thats due to a weird fuel air mixture since i put my tb spacer on. but the transmission is acting up. i checked the fluid and its good idk what it is.

just drove it again now, ran fine. shifted beautifully check engine light was off, i reset the aldl plate with a paper clip earlier so it makes me think its an electrical or sensor problem? or maybe the tranny was cool and the servo was behaving? also could the rpm dipping be a choke problem?

usually a high idle is a vacuum leak some where.
