MY KA24E IS SCREWED!!!! RPM JUMPS, JERKY AS HELL GETTIN WHIPLASH

[SOHC1allday]

drove home ok when i bought it. took it on a hour drive started problem in 5th gear cruisin 55 at about 2800 rpms, it started jerkin like hell rpms jumpin up and down, i slam the gas and it goes fine until you let up a little on the gas then its jerky as hell again, then when i slowed down, first gear all the way to fifth are screwed can barely go anywhere while im getting whiplash from jerking so much haha. its perfectly fine in neutral, sometimes it only jerks when its warm, sometimes it will do it when its cold.

got new MAF, water coolant temp sensor, plugs and wires, distributor cap and rotor, auto ecu. still screwed only code its showing is air intake temp sensor, but i really dont think thats it because i accidently pulled out the sensor wires when i was changing the MAF, and it had the problem before that? but may of already been going bad? can the air intake sensor cause all of this? dont know wat the hell to do anymore SOMEONE PLEASE HELP ME!!!!!!

have u checked ur injector plugs? the plugs or the part where the wires meet the plugs tend to wear down causing a bad connection, i had a similar problem after changing out my injectors and found out that the plug wires were dropping the connection to the injectors. just my 2 cents
