CRX Si Throttle body

[djdiego]

Yo my 89' CRX Si throttle is posively damaged or at least the TPS (throttle Position Sensor). My RPM's are jumping like crazy if this is the problem could I replace the hole throttle with one of a diffrent engine like b18 ????? what is compatible to a CRX that will have more Diameter and will fit my intake manifold. Also would a diffrent Manifold fit a CRX to achive a hole conversion??? Please guys help me out...

You have to have it bored out by a machine shop and replace the "butterfly", or purchase an aftermarket TB to up the size of it. There aren't any factory TBs that I know of that will bolt up and are bigger than the Si. On the brighter side of things, a B series TPS will work on the D series, and the other way around.

fluctuating idle is not problem with the throttle body - usually EACV problem or low coolant level

EACV????????? Not following u sorry man please explain. Coolant level just fine!
