car still wont drive right :/

[silent_elite]

hello again nico ppl, thankyou for all of you who have got me this far lol

so car still aint right. starts up and idles at 900rpm bouncing jus a lil bit every few seconds. iv put in a new tps and adjusted it to .47, leave it disconnected for a bit and adjust iacv. go for a spin hoping iv fixed the jerking, drive for 30sec and the jerking starts again. it only happens every now and then it will start giving you wiplash and rpms rev to 2700 real quick then down to like 2500 but if i floor it a bit while its doing this it drives out of it. i park and check my tps and im gettin .52, did i not tighten it enough? and if im parked somewhere after driving for a few mins and im in neutral car idles at like 1400 and when i give it gas the temp needle moves up and down real quick but when i go into 1st it idels bac at 900 and needle stays level. also feels like im not getting that much power, ill be in 1st and have the gas to the ground and it jus gradually accelerates but sometimes i get a lil bit of pep from it. i just replaced the fuel filter and it didnt jerk NEARLY as much and im bout to order my 255fp. so what do youll think nico?

thanks guys and sorry for the long sentence lol

ur tps might just have crapped out on you, as for the quick rpm pick up im not sure but check to make sure ur throttle cable is secured and not getting tangled or interference

when my tps went i felt a substantial power loss along with erratic rpms

its a brand new tps
