About 2 weeks ago i got a check engine light,car drove fine and being the procrastination king i am i havent checked the code,well about a week ago i was driving home from woork and i was at a stop light,light goes green and i start to go but the car seems to move very slow off the line until i get up in the rpms.I thought ****..my tranny is starting to go,so i get home let the car sit and go back out to get gas(car was low on fuel)it drove fine then.

So today im leaving work and i get a race with a modded ls2 goat(put a big hurting on him )and right after i get to a light,and when it goes green the car moves very slow off the line again until i get up in the rpms..****..here we go again...anybody have any advice on what it could be...the car moves very slowly off the line when i get on the gas until i get up into the rpms its almost like my stall is super super loose...wtf...can anyone help

this really sucks because i was gonna have my heads put on soon...but i think i might have to splurge that money on somthing else..Tranny/new verter

 

Sounds like limp mode which may just be and electrical issue , I would get it scanned and find out what that code is before I do anything may be something simple .

 

Thanks for the quick response,i will get the code checked asap...you guys are the ****..i was thinking in the back of my head that it could be limp mode but didnt know what would trigger it..thanks again

 

Your welcome when you get the code let me know and ill try and be of more help .

 

Its code p0757...Is that one of those BS ecm codes it throws for a high stall...Why would this code trigger my car to go into limp mode...thanks in advance..

 

Thats is a code set by high stall converters sometimes and it will trigger limp mode, You will need to see a tuner and have the test for that code removed from the software on your PCM , This code sometimes comes up imediatly after a stall sometimes never and sometimes after a while. But it does sound like the issue you have.

 

Thanks again...i will be upgrading the trans soon and you guys will definitly be getting my business ...

 

your welcome
