Hey Guys,
I want to thank both of you for your help. I took the valve off and cleaned it again and this time I sprayed some Teflon based lube in it. I put it back on and after a couple of days the light went off and hasn't come back on since, knock on wood.

Default I'm Back

Well guys the check engine light is back and it seems the idle air valve it giving problems again. It would put a big hurt on my wallet to buy an OEM valve. I started a search and found this valve which is spot on identical to mine, but i'm sure the electrical connector will have to be modified. But to save a couple hundred bucks, I'm willing to put in the work. Check it out and see what you think?

What code are you getting? (or does this mean you haven't bought a scanner yet - they are not expensive, and really necessary to have in OBD2 cars - you are able to do live data scan which would confirm what the computer is seeing, rather than an expensive guess by replacing the idle solenoid valve). In any event, the compatibility chart on the Amazon link does not show that this is compatible with your car...Ford Focus? Crown Victoria? No Suzuki listed. Yours looks like this:

bex, its a 1.8L not 1.6L a diff. ISC. (it is a 14ohm diode clamped , ISC , testing is tricky see my page warnings.)
why do you OP thank it needs new one. (what ever it, is )
i'ts a 1.8L sport.
wrong parts, WOW , you are kidding right?
you dont want to do that, you risk burning up a good ECU, ever price, 1.8L parts.
much less find them.. .not easy or cheap.

Please say what it does good and bad,,,, i guess idle but give exact examples
like it idles to fast or too slow.... ?
and actual RPMs
hot ?
cold
both?

the 1.8 liter has 2 valves, (3 really)
EGR (cause low idle)
ISC (causes low or high idle, if you have air leaks , in the plenum the iSC can loose control easy. and cause high idle , even though the ISC is 100% perfect in all ways, got that?
and the one on top the TB that is the cold start solenoid. the PLUNGER thing,. (this is for starting engine, it MUST retract , does it?


what codes, you never posted the DTC codes..?
a code reader is what $30 and full scan tool like $50.
why work blind? (it's only 1 tank of fuel this tool)

fail mode 4
the 1.8L TPS sensor must hold 0.5v at idle or idle will go nuts.
the 1.8L has idle doohicky on top of the TB, (my v6 does too) this device needs to
be looked at first. if it hangs , hot idle will be too high and the ISC will fail to work right.

this doohicky is called, the fast idle PLUNGER.

here is a photo. (this must retract 100% DOES IT?)


if you can afford to guess, and throw parts, Ill bow to you...
and blowing an ECU to hell, is really, crazy.. idea...... sorry, but it is....

here is the shop manual. (found with google J18 and plunger)
the plunger devices is water activated, (just like our old IAC)
The A distance above, is
1.048 to 1.078" at 25deg. C (77f)
start car, it retracts to OFF CAM
at 126F to 154F.
in not , this first test fails

fsm, 1.8L
"suzuki j18 motor idle plunger"
page 632 and page 657 .

done upgrading this link now (see 1.8L) see fsm link there. (a huge pdf)
I got a bad idle , cold or hot engine!

Hey Guys,
I got my hands on a code reader and got P0505. The engine idles fine and runs fine it is just the check engine light is on.
