shrug Posted August 27, 2019 Report Share Posted August 27, 2019 Anyone else come across RB20 / series one 25 tps always coming back to a different closed throttle position from not being sprung? Had this issue on two cars now albeit it both with aftermarket throttle bodies, one owner did try epoxying it to the shaft of the throttle body but didn’t make any difference, keeps putting ecu into decel from seeing closed throttle on partial throttle (just off idle low rpm cruising) then no decel from seeing like 1-3% throttle next time u open and close it. Anyone know any spring return tps that use the shaft design to ditch these horrible things? Both tps are both brand new genuine Nissan ones too so not faulty tps causing the issues.

Leiden Posted August 28, 2019 Report Share Posted August 28, 2019 Remove the 'D' adapter from the shaft, drill a pilot hole and fit a pin so you can run a S2/Neo TPS, have done a few of these conversions now as the S1 TPS is a piece of garbage.
