Hello I got a 91 hatch wit a b20, skunk2 intake manifold and recently I swapped out the stock throttlebody to a aftermarket 70mm. The new throttlebody doesn’t feel like it’s sticky at all so it’s not getting stuck and the tps is calibrated to .50 when closed. I’m using a 94-01 integra throttlebody cable, I don’t know if I should swap to the 90-93 integra cable. Will that make the difference I need? If do please let me know.
For some reason when the car is warmed up and I’ve been driving around for a little while the rpm will get stuck at around 2000rpm when im coming to a stop and in neutral or when I clutch in, then I would have to press gas to rev it a little so the rpm would drop super low then it goes back to normal idle around under 1000rpm. Kinda lost help

 

I'm still new at the car stuff but since no one else has any suggestion,

Do you still have an IACV? Have you checked that it does not stick

 

Yeah, ever car need a IACV. And it's still a good one, I remember cleaning it out not too long ago but maybe I should reclean it lol thanks for the input and good luck with the car stuff!! Headaches at times but all worth it in the end!!!!
