Wanted Rb20 Tps

[Tommyd32gtst]

Hey looking for a throttle position sensor for a rb20det in a 1990 model r32 gtst 0408306124 cheers! Sometimes when I drive it will cut the revs at 2000 rpm and drop to 1500 and bounce between that at wide open throttle like a rev limiter if I take off in a higher gear then force it into lower gear n get the revs over 2000 rpm then it's fine to drive until it drops back under 2 grand, have tried a couple air flow meters and swapped ecu's any help is appreciated thinking TPS or cam angle sensor
