does it run fine after it is warmed up or does it seem like it is going to stall?

I'm going to junk yard in morning to grab an iac valve then swap it in and see if it changes, then I'll mess with the screw.

Seems like it's going to stall and I can make it stall if I'm not easy on it.

Yeah it sounds like your iac is probably bad on it,does the idle needle seem to bounce around

No, bouncing. I'll pulled the iac and turned on the key and watched it. It moved out then in then out a little then stopped.

Has it been idling at least since you cleaned the iac?It seems like the iac would be working then.Maybe the fiav(fast idle air valve) is bad,it could be clogged.

It is part of the throttle body where the coolant goes through,i think yours is built in to the throttle body i am not really sure.If changing the iac doesnt help i would see if i can find a used throttle body,the fiav allows the coolant to go through and warm up the car then it shuts after a certain amount of time.

I'll know the cold start tomorrow as I adjusted it while car was up to full operating temp. The rpm I set it to is 850-900rpm

Ok cold morning start and no fast idle? It was a hard start and around 600rpm till it warmed up. This is why I didn't want to mess with the screw, I'm not stupid I knee it was something else. Damn!

Dont panic is ok. I told u u need to let it idle for 14 min no driving. My friend has a iac motor i could get it for u. Pm me. Coolant on the iac has to do anything with the idle. Mine right now is bypass for the summer. The pcm has the settings for engine warm up. When cold engine rev around 1500 to 2000 rpm to get to operating temp and it should to down to 700 to 800 rpm. If you dont get that jump to 2000 when cold the iac is bad.

Ok so I'll reset then let idle 14min then drive it? Or shut it off then drive?

Yeah the iac deffinantly seems to be bad,just give it a day or two for the computer to adjust and if it is still not getting a high idle the iac is bad like i said it was.

You need a real-time data logger.

You said you cleaned the tb right. My question is did you Plug the bypass passage inlet? If you did not there IS YOUR PROBLEM. it is probable that deposits are adhered to the Bypass passage inlet when you sprayed it. So, you need to clean the passage with tb cleaner. Here some pic of what I'm talking about.

The two holes pointed by the arrows.
Spray cleaning solvent into the valve through the throttle body intake port and leave it for approximately five minutes. Start the engine, rev it several times and then idle it for about one minute.

Adjust the screw if the rpm is higher than 1000 RPM or below 500 RPM It needs to be around 750 to 800 RPM. Let it idle for 14 min. Also you need to drive the car for 300 Miles so the PCM could adjust it self.

I did not plug the bypass inlet or remove the idle control. So you think I should remove the idle control valve and spray down into the bypass inlets? Let it soak 5mim. Then fire it up, rev a few times, then idle for 1min.? l The go drive 300 miles? Lol joking bout the 300 miles, lol thanks I'll try what you said.

The computer will actually reset itself after 100 miles not 300

NO leave the IAC alone. Just spray on the 2 holes. and fallow the procedure.

For most of the setting YES. But coming to idle and other things. You need to drive it more for 100% acc. Is around the 300 mile mark.

When you think about it 300 miles is not that much... One gas tank, say a week.

yeah it would just suck if it didnt work and he has to replace the iac anyway
06-13-2011, 05:20 PM
Isaurio

Yeah. its called troubleshooting. But still if he replace the IAC you need to drive the car for a few miles to adjust the new readings. Is all calculation from the PCM it needs to take the new readings and it uses formulas to convert the reading for something more stable.

Well I removed iac before u got back to me and now I'm resetting the PCM now. I'll let it idle for 14min. My Haynes manual said 10min. But whatever. Then I'll go drive 8000 miles lol! For real I'll go drive around a bit just to get the screw adjusted, cause I'm sitting here and the idle is around 1400rpm so I wanta lower that then drive a bit to see if it will stall or not. Thanks guys.

06-13-2011, 07:04 PM

Ok I adjusted the screw, it's all the way in, and I rev the gas and the idle is now stuck at 1600rpm wtf?????!!!!!

I turned it clockwise all the way and if I turn it counterclockwise the rpms go up.
