ok so i just put my ZZp stage 3 kit on my car, had it running drove fine for a while. Stopped at a store and after that on the way back across town i noticed the idle issue kicking in(i read the sticky and cleaned the tb prior). Then after that i came to a light and when i tried accelerating the car would go for a few seconds then seem to stall and die for a few seconds and then power up angain and then stall. I also got a P0507 code for idle higher than normal. Any ideas?? help

 

vacuum leak or coolant leak be my guess to start from other threads, get some tb cleaner and spray around tb, and blower gaskets and if u hit a spot were motor stutters while spraying, done, vacuum leak found, if not go after possible coolant leak, there was one member who couldnt boost past 4000rpm from intake gasket leaking coolant and then found jacked up Livonia cores/seals, also lost a washer from a core and had to have one made

 

thanks that helped alot, no vacuum leaks found but i pulled the intake and found two of the o-rings on the endplate had knicks in them, causing a leak to the intake manifold.

 

I might be incorrect with this or not, but

I beleive that ZZP Stg 3 USED to be 60lb injectors,
and I think they switched their Stg 3 to 50lb injectors.

That stated, what size injectors do you have? The LSJ Idles poorly on 60 lb injectors, hince then change to 50lb injectors. If you have the 60s, you'll need a precise custom tune to get it to idle properly.

I have their Canned Tune, and 60s, and my idle is kinda funky, but it doesnt throw a code, and so I just deal with it, since I'm 900+ Miles from ZZP. maybe sometime this year I'll head over there on my annual trip to Michigan.

 

see if there's any way you can data log your car and send the ecu in for calibration... or do 80's and e85 with a proper tune

 

luck me when i get to building a lsj of my own im only 150ish miles from zzp, thank god for loving cobalt ss/sc for 5 years and living by saginaw mi hahaha

 

If your in saganaw, arnt you closer to OTTP?

 

iv gottne the po507 code a few times after the stage 3, i only get it if the car stalls out, or if the gas is tapped at the exact right time and the car stutters, then it throws the code and i have to delete it with my scanner cause it runs like **** when its on lol. idk what causes it, i checked for leaks and such and nothing.

 

i'm sure only a REAL remote tune will be able to fix this

 

thought about taking the car out to intense this spring to get dyno tuned. any other good tuners in PA, i kno of BYT but he hasnt been on here much and i dont wanna get tuned by a place thats not gonna be around all the time to help if problems arise. BTW sorry to thread jack.

 

i am, but i havent heard a whole lot of good things about them, i havent really heard or seen anybody bash on zzp to much n as far as i know they are the leading company in our community, the only thing im really considering buying from ottp is the return style fuel system, every thing else i was planning on zzp, ttr, ark performance for the springs/short throw, unless enybody on here has anything other to say about ottp for certian products/possible tuning, i still will be doin major buys from zzp for there staged kits and turbo kit when the money is right for me

 

HA HA, that was me with the effed up cores. Tim had me replace my ebay intake with a zzp cia and fixed my no power and idle issues.

 

ost u like 300 for cores didnt it?

 

yep 350, shitty learning experience. BE CAREFUL WITH YOUR CORES.......................

 

no **** lol
