Thread: throttle/idle issue

1994 SR20DE RR, finally found the culprit of my bad gas mileage, (BIG thanks to Andreas)...turned out to be the number 2 injector o-ring leaking and burning off down into the exhaust manifold. So, I timed it according to spec and all went as it should and it idles smoothly right at 800 rpms. Only issue I have is when I slow down from a high rate of speed say slowing down to a traffic light the idle drops down to about 500ish almost like it's going to stall for about 10 secs and then eventually smooths out back to 800 rpms, even stalled twice...suggestions please.

Have you cleaned your iacv? I clean mine everyone in a while when I notice my car doing that

IACV is relatively new but I will try

This is what I am experiencing. I have cleaned and tested both the IACV and AAC. Cleaned PCV and my throttle body is clean. Was the cause of this ever figured out? I noticed there is a crack in one of the creases of my throttle body intake hose. Also, when I put a voltmeter to my TPS with the ignition on, I get about 5 volts no matter what position it is in. I have no idea what it is supposed to read. Any thoughts?

Your base idle is set to low. Get it into timing mode and raise it some. Even if you cant do this just raise it a bit anyways

Haulin200sx, thanks. Do you think I should do that even if the idle eventually will settle at around 750?
