reading codes po340 and po300

After cleaning the IAC, what are your present issues?
You need not follow the troubleshooting to the dot. You stop when the problem is resolved.

Okay I need to know how many volts from the iac plug that plugs into iac is suposed to read? Im reading 9.33v and the iac is not openning at this voltage ,But when I use a jumper wire from 12 v battery it opens.

I also reinstalled the iac and started motor idle is still high and after warm up it idle come down to a stall out motor,I took a code reading and po505 is gone,but Im reading a po510

You don't seem to be doing things correctly and instead of solving one problem, you created another.

P0510 is a fault with the TPS.

When cold the idle rpm would be high due to the cold start system.

How would u know or even say that when u just jumped on board with whats going on with the car Im working on? who are u anyway? I was dealing with saturntech9 and out of no where u appear! Its hard enough with one person and than switch to someone who doesnt know where Im at ,,at this point,This car has had a high idle from the beginning ,You never answered my question about how many volts is supposed to be coming through the iac plug,,,????

The blue wire with a black tracer going to the iac should have battery voltage with the key in the run position?It gets power from the fuel injector power feed wires.

I had been following what you had been doing from start till now and knows what is going on.

Sorry for being nosey parker. Have a nice day since I am not welcomed here.

okay this is to saturn9,,Motor has come a long way from the start of all this the idle is still to high even when hot,the surgeing has stopped,there are no codes after I took it for a ride.But idle is not stable sometimes it will go so low it stalls motor

One more thing Im not sure this iac is operateing properly. trouble tree says to turn key in on position and blow through air tube to see if iac switch is open,It is not open cannot blow through tube.

So do you have battery voltage on that wire i asked you about with the key in the run position?

Yes

So you said the iac works when putting power and ground to it?

Yes while holding it in my hand power right off battery

Also test drove it a couple miles and No cel

Have you checked for vaccuum leaks?

Yes ever since this car started giveing me trouble, Iv sprayed carb cleaner around trying to check

Im wondering if this idle problem could be a timeing issue? I did try timeing it with lite and it is off the proper mark of 4-6 degrees,,,,I copied this from suzuki forum

When your valves are timed properly, your compression should be in the area of 190psi on all cylinders. So timing is off. As Rhino says, check the crank keyway to see if it is sheared (although crankbolt torque - which should be 94 ft/lbs, was normally not an issue after 1996). Timing belt is timed to cylinder #4 firing, with the crank key at 12:00 and the cam key at 6:00. Then ignition timing is set to cylinder #1 firing. Check your timing.

So is your timing belt timing belt timing correct along with your timing checking it with a timinh light?

I will look at that too ,I also found that my throttle cable is touchy,meaning that when i move it the idle gos up and wont come down untill I push the throttle back down ,,so it is getting replaced

Sounds like your working all the bugs out that would explain a high idle.Keep me posted on what you find.
