Alright guys. I got a 97 vert with a 5sfe. I just got it and am now having issues. One of the vacuum hoses fell off so i bought some clamps boom fixed right? Guess not because on the freeway my car will jerk violently if i dont either depress the clutch or slam on the accelerator. Car is very sluggish and will not go past 4k. And usually jerks when i hit about 70. The only way i found to avoid the sluggishness is revving it high when taking off and slowly letting off the clutch wearing it down very very fast im sure. My question is what in the world is going on with my car? Both the sluggishness and the jerking at higher speeds. There is also a slight whine or whistle under the hood from when the hose fell off that didnt fully go away. I really need the advice as this is my first celica and my first own car. Anything helps! Thanks.

So you can go past 4K while in neutral but not while in gear? And while idling the engine doesn't shake or idle rough, just has a whine to it? If this is the case, definitely recheck your vacuum lines, check where the vacuum line went to and see if there is a clog in the system, if so run some seafoam in through a vacuum line. Maybe check your map sensor too by unplugging it, once with the vacuum line and once with the connector and see if there is a difference. Also did these issues happen before your vacuum line issue that you had fixed?
