Running like crap please help

[greyspyder117]

OK so i was given this 98 GSX about 2 days ago and i can't seem to get it running right which was the reson it was givien to me (cause nither could he) Now i haven't gone to crazy trying to figure out what the problem is yet so it's not a headache yet. Anyway it sounds like it runs very nice at idle. The fuel pressure is 43.5. It has a FMIC and a Evo3 16g. I did a boost leak test and tested up to 18psi and it's fine. It strains taking off in 1st gear but at soon at the turbo starts to kick in maybe around 2800rpm it pulls like i think it's suppose too. I am getting codes for front 02, rear 02, and evap system. The exhaust is broken right after the flex pipe. The BOV is recirulated. ANy idea guys or need more info so i can get the right answer? Please help

If your getting codes for the o2 sensors then you need to replace them, they are what tell the ecu how your fuel etc needs to be. Also, having unneeded back pressure from the exhaust having a leak will cause the o2 sensor to read wrong as well, little things like this will do a lot..

OK so i will start with front 02 and fixing the exhaust. THen if i still have problems i will write again on Tuesday... I don't think any Automotive store is going to be open tomoorow for me to buy the 02 sensor.

You should be fine if you fix the exhaust and front o2, the back o2 I'm not 100% sure about though.

As of today i have dsmlink v2 in the car... It has 650cc injectors and i did the quick injector value that can be found on ecmlink.com i think it was -31 with 280 deadtime.... The car came with ecmlinkv3 but i didn't have the cable.. I had dsmlinkv2 in my 97 Spyder so i swapped the dsmlinkv2 out of the 97 and put the stock computer in the 97 since i don't have bigger injectors installed in it right now one in then i but the v2 in the 98gsx. Why do you ask?? Is their something i can look for??? I know that the front o2 sensor is stuck on 0.4v and won't move but i only logger it at idle and for maybe 9 seconds
