Low Idle R33 Gtst S1

Hey guys lately been tackling a little issue with my idle. What is happening is once the car is warm at opperating temp. The revs sit at say around 600rpm when im sure its soposed to sit up around 900rpm for a manual. Anyway i checked over my vac lines and there was no leak that i found though i did look at the intercoolerpipe and noticed that it had been rubbing on the chasis and caused a cut throught the driverside bottom pipe so i used multi metal epoxy and patched it up (good stuff by the way i recomend it ) but still had the same issue i also tried cleaning the aac and resetting the screw but still i turn the screw nothing changes when i want the idle to rise but when i turn it down the idle drops.... I also played with my tps yesterday and notticed if i adjusted it forward it fixed the problem. but once i turn the car off it resets back to the way it was before.... Any ideas guys?????

Set the tps to .4V

Check the ignition timing

sorry but how do i do that? multimeters???

Multimeter or consult for the tps. Think theres a DIY on this.

An a timing light for the crank angle sensor. Same as setting up a distributor if that helps any.
