98 ek with 96 gsr. idle is 2-2500. I took off the iacv cleaned it in solvent over night put it back on the idle dropped down to 1400. then I realized I didnt plug the sensor clip back in. idle went back up.

if I get another iacv will it work or should I go onto other things? what car would I have to get it from?

i read 96+ engines dont have a fitv. but I can see what looks exactly like one under the throttle body. I dont want to go in there cleaning it because its looks like a Bitch. is that the next step?

or does un hooking the iacv wiring and that happen show something?

thx!!!

engine lights?
if so which codes?
make sure the engine light illuminates for 2000ms(2 sec) when turning key to II position before start.

the engine light doesnt work. even with a new bulb so till I get that scanned I guess nothing I can do? I was hoping someone could tell me from what happend with that clip not being plugged in.

beecee18

it overode the circuit and used input from other sensors to get the info needed, probably putting the vehicle into limp mode,
check for hissing and vacuum leaks also

SiRCiviC94

nothing like that no hissing. but a high 3000 rpm start up at settles to like 2200. I cannot wait to fix this

Have you tried adjusting that screw for the idle?

Quick question, do you have the stock intake manifold? Reason I ask is because the skunk2 intake manifold fits both the 2 wire iacv and the 3 wire iacv. This can lead to some idle issues if you use the wrong one. BTW as far as i know when you unclip the iacv sensor, your idle is suppose to drop down.

If your engine is utilizing an OBD2 ecu you must check for cel's and let the codes tell you, an idle that high must be from a fault which would trip the sensor, soooo fix the engine light problem first, or plug an OBD2 scanner into it.

What ECU?

Check whether somebody cut the CEL wires.

P72 obd2 until I get a jumper to run a chipped p28

Im searching for my scanner....Erase codes and go
From there

Stock manifold and tb.

Throttle plate is right shut and idle screw closed

Dont clear them write them down and convey them to use on here,

then erase them and check to see if/when they come back, most OBD2 codes will take 2 or more trips to come back so a few drives might be necessary.
If the fault comes back instantly after clear/reset then you have a fault in the wiring.

you want my opinion, I thing that something physical is causing the high idle
something like a vacuum leak, search and find the best way for you dor checking for vacuum leaks, it is not hard.

^^ sounds physical i agree. but were only taking shots in the dark until you (OP) can report some CEL codes.

SiRCiviC94

I'll look more today for the reader. It's not a fresh swap I'm pretty sure it ran somewhat normal in its history.

I mean erase them as in find the codes (ex knock sensor and o2 sensor) and have those disabled in the new basemap.

Motor has been in limp mode for a while it time to open her up


One open vac line one the tb I searched and it isn't or anything I just caped it off
