well guys, i got the coolant in the system today, just started it up to make sure all was good, still waiting for my meth (wil be here wednesday), i got the zzp pcm and #50 injectors and dual pass, s3 heat exchanger and 3.0 pulley. i started the car everything was fine BTW i did not drive the car or rev it past 3k. i tapped the throttle and got miss, threw code # PO507, it said "idle air control systems revolutions per minute higher than expected". i shut the car off after it has done this twice and once i go to start it back up, its fine, idles smooth and is good. any idea what could cause this?

 

Any type of vacuum leak, or a bad t.b or the tunes off.

 

alright im gonna go check some lines and see what i find.

 

all the vacume lines are good and i got the meth up, jsut took the car for a test drive and the ONLY time this code comes up is if the engine sputters due to, throttle hit really fast and let off when sitting still, or if you lug it starting out, i mean you have to lug it pretty bad. once this miss fire happens, i go in, delete this code and the car is fine till it comes back. what could cause this?

 

Either your scaled for a larger t.b or Ures is bad. And also you shouldn't be sputtering at all!

 

when i ordered the tune, i selcted the stock TB. i really dont kno what would cause this with the stock TB, i cleaned it when i had it off to put these parts on.

 

A bad t.b or the scale is incorrect.... That's mainly it. so either they scaled it wrong or its bad.

 

alright so where can i get a new TB? how much am i lookin at? one thing i dont get is, the car was fine before i done anyhting to it. no coed no nothing for the longest time. BTw i am running a ZZP TB spacer with meth. but the spacer is after the TB.

 

I know the code is a high idle, meaning the.scaler is wrong or the t.b is bad. Or somthing else to make it idle higher then it should

 

alright well i really dont kno what to do at this point, ill prolly pull it off tommorow, clean it up and go over it again.

 

Ok.. is contact zzp as well.

 

Man im in the same boat, same mods but no spacer, no meth, 2.8. same code thrown. idles fine till you pop the throttle then acts like a mis or no fuel kinda baffling idle and cant make it accellerate with out feathering the pedal.

 

how are you clearing your code?

 

im using a actron scanner/diagnostic tool. its the model 9580. its the same problem as you just said too, have you repalced anything?

 

All my mods are new, these issues started at my first fire up after installing everything. I topped off the filler neck with antifreeze this morning with it running and it took a lot more than i thought. i sprayed starter fluid in the areas that i know of for vac leak and nothing, sprayed some sea foam in the throttle body and its running fine in the garage. But it hasnt acted up this morning at all so i dont know if those things affected it. i cant drive it today cause its dumpin cold white **** outside. on my thread about this 'mrbelvedere' says "do a boost leak check you can reset it all you want but if the high idle is because of the new learned blade postion then the dealer has to do a learn down with a tech2" so im not sure if thats the fix.... Thoughts?

 

Ok update, i think turbo tim is on to something. So he thinks i am getting coolant from the intake mani in the engine. well 1st i thought no way i was carefull with the install but i thought about it, i topped off the filler neck and drove it= white smoke and then less and less smoke, get back home and need to top it off again, drove it next day= white smoke poofs and then less and less, get back home today have to put in about 1/3 of a gallon again. So i think thats it, i dont know what to look for when i take the I/M off. its gotta be the cores, thats the only place it could leak in right?

 

did you bleed the heat exchanger system??? Btw, when you top of the system, are you just using dex-cool, or a mix of dex-cool and distilled water??? Either way, the smoke in your exhaust doesn't mean it's coming from the intake mani, it means there's coolant getting into the combustion chamber from somewhere. Check your oil and see what the color and consistency looks like before you assume the leak is coming from the intercooler system.



OP, listen to james...he knows what he's talking about. Before you go and buy a throttle body, have someone in your area with HPT pull the tune off your pcm and send it to james or zzp. At least that way you can eliminate the tune if that's not the problem.

 

i bleed the system as much as i could, no one around here has dexcool so i used autozone brand 50/50, they said it was ok to mix them. i lloked at my dipstick and didnt see any milky substance or coolant. Who is James? and how much coolant does the H/E system hold? im almost a gallon in right now and i know i didnt lose that much during the install but i guess the new S3 H/E takes up some volume.

 

it all depends on how you are running your system (option b, dual h/e, just the zpp stage 3, etc.). The zzp stage 3 alone takes significantly more coolant than the stock, which is essentially why you're buying it. Aside from the better flow of coolant, the fact that you're adding more coolant allows the system to cool air temps more. So basically, if you're only a gallon into the system, you're probably not putting enough in.

Secondly, DON'T EVER ******* LISTEN TO THE STUPID JACK-TARDS AT AUTO-ZONE!!!!! At the very least I hope the fluid you put in is the same color as dex-cool. Different coolants have different cooling properties and chemicals to cool the system. Even if the yellow **** is universal, you still don't want to put it in your lsj. Only put what came from the factory. Otherwise you run the risk of ruining gaskets....

Lastly, james is chevycobaltss3

 

i am running stock and S3 H/E, dual pass, no option B. i think i should atleat pull the mani just to see if coolant is in the valve chamber? i guess 1st i should look very carefully in the oil. head gasket would suck. i should know better listening to those doofs. should i flush that chit out? same color but auto zone brand.

 

just compare the ingredients to dex-cool...the worst you could have done is put the green coolant in your ride.
