Help! engine codes... - SRT Forums

Calcity_SRT4 · 04-25-2006, 08:39 PM

I have a check engine light on got it scanned and the codes are p2074 p0234 p1188 p1697... They started comming on after i put on the AGP WGA. only other thing that is done to the car is a BOV and a Intake. my wastegate is set at 17 spike and 15/16 at redline.

Tomarrow i'm picking up my Tach adapter for the S-AFC and 750cc Rc injectors I'm ordering my exhaust tomarrow deciding between the MPx or the thermal right now.

I have a 2005 ACR. When i erase the codes car runs great but when the light comes on and i Floor it, it seems around 4500 rpm it kinda like dies off hp curve seems to just drop down about 75hp or something so its real irritating. what do i need to do to correct this issue?

FYI i got the 750cc i know they are a little too much for the stock turbo even at 20psi, but within 2 months i'm planning on doing a big turbo/Intercooler upgrade so thats the reason behind that.

Ok so to fix this.. P0234 turn boost down. P1188 just check my pink line. P2074 i'm not sure i follow to to do that one. and P1697 my Odometer broke??

How would i fix P 2074 and P 1697?

About the P0234 is it because too much boost not enough fuel? or when i put in the injectors and tune it with enough fuel it will still throw it? pfff...

to get rid of the overboost code either have to get the tip mod for the 05 or get s1 pcm...the s0 pcm dont like to much boost goin to it.. so it is programmed when it sees about 18 or so psi it goes to overboost... it uses the tip sensor(pink and white line) on the soleniods...one of the other ones have to do with over boosting too cant remember which one.. ill look it up...umm about the odometer i have no idea... try to keep your car in reset mode all night... open your fuse box, if you stand on the driver quarter panel theres a 15amp fuse on the bottom left side its the 20 right above that. pull it for 10 secs try that for a night.....see what happens....

GET S1 OR THE TIP MOD... or u will keep gettin codes....
i use to run 19-16 psi no prob on s1...(used s2 waste gate) look at my s1 dyno in sig..

I used to throw EVERYONE of those codes all the time, I got stage 1 about three months ago i have not thrown any codes since. It was a great 350 dollar investment! Just something to think about.

s1 is not a real big peak hp gain.. but it does help in the power band alot.. some spots 20whp but peak wize u will only see about 10whp.. what s1 does that helps the most... it gets rid of the bull shit codes you get from modding..also it give you more fuel.... no prob for the help.... that is why i get on so much.. (and to talk shit)
