I'm lost, I have a 2000 Civic Hatch back with a D16Y7 car used to be automatic I did the manual swap, also I did the Y8 intake manifold swap NOT THE HEAD just the intake manifold. I'm having issues with the RPM car runs good until I give it gas slowly exactly at 1500 RPM it sounds like its rev limiting but I give it more gas and passed 1500 it runs fine, when I drive it at 1500 it jerks really bad like someone is learning how to drive manual for the first time I give it gas and it goes passed 1500 it drives fine, I do have CEL for an O2 sensor, I've tried new tps calibrated it still same thing IAC valve is new, plugs and wires are new and still nothing, I'm completely lost and I need help bad

 

i've installed some sketchy tps before, blox and ebay brand x were both sh*t. f u blox! 8(
dorman was the brand that finally solved the prob.
make sure you torque it down good with bolts, screws aint gonna cut it , it will just drift out of spec eventually.

 

so you really think it’s the tps?

 

it's possible what brand is it?
double check the calibration.

 

it’s doorman and the calibration is good, I haven’t checked it since I calibrated but I’m going to do what you said about the screws. I’m gonna get bolts for it and see
