Thread: Need Help for high idle

i dont know why my car after pnp i install back my q45 throttle body and then my idle go to 2000rpm when the car warm up..... but previously i still not pnp my car running smooth idle. and then they change to normal intake and throttle body everything is smooth... can anyone help me figure out.. is it the wyring got problem and will effect the high rpm?

This is my intake picture

You prob have a vacumm leak. Check the manifold, welds, fittings, throttle body gasket ect.

but last time when i install this throttle body and manifold also got this problem the rpm always at 2000rpm ... on that time i drive a car and hit a water then my car suddenly normal back... to 1000rpm

you should be at 850rpm for idle unless u have Frank Stage 4 cams.

on that time go to 1000rpm then i give people tuning back at the 850 to 950rpm is normal now i dont know is it the wyring going wrong or some where not plug in.. idle so bad
