Hello Guys!,
I just bought recently a 97 GSX, I am new around here and to the 4G63 realm all together. It has been a very steep learning curve with a new engine and turbo but I am holding on to it and coming up slowly but surely!
So I got a few issues I need to iron out but do not know where to start. I hope I can get some guidance from you guys, it will be totally appreciated. Also how can I figure out what injectors I have, and any other parts I might need to know. Cant tell what size turbo I have or none of that.
These are my issues:
1) When I rev (mostly 2nd gear or higher) above 3.5k rpm the car stutters real badly. RPM and speed keeps going up but the car keep stuttering a lot ( like going up on a cobblestone road) Only happens at 75% or WOT and it happens regardless after 4k rpm.
2) I got CEL! The shop that previous owner used to take it to told me the car only needed a Camshaft sensor after getting one, replacing it and clearing the codes, CEL P0340 keeps popping up. (Is there any special procedures to install a Camshaft Sensor?
3) Now trusting this so specialized performance shop that had worked on this car several time, I had pulled the codes on my own and find out that I am getting P0335 and try to follow the a disconnected cable (after looking at diagrams, pics and vids) down towards the crankshaft sensor, guess what? No Crankshaft sensor wire? Attached a picture to see if you guys could confirm whether I am missing it or not.
4) Having issues downloading the ROM. I took a plunge and even though I am new to all of this I lost my trust on the shop the previous owner took me to, specially after making me wait 4 hours to tell me he would not be able to help me that day and over hearing him having an argument with a customer just because the customer had no updates about his car and it had been weeks of broken promises. That said I bought an openport 1.3u was able to connect and download the ROM but it tells me unknown ROM. I downloaded several Tephra XML definitions to no luck. I can open Tephra ROM but not the one I downloaded.
5) Car does not start up like stock, or right up. It takes a bit of cranking to start up. I changed the IDLE valve Sensor and it did not do much. Any other suggestion?
Pardon if it is a lot of information. I really like the car and Im working on it to get it to a base level before I can embark on the real project for it. I hope this all makes sense as it might or might not sound so newbie but I just did some reading before post as I did not want to come here clueless. Please let me know if you guys would like any additional information that I can provide. I have logged the car and attached the file. Im still learning how to read them. I can understand some, but cant see the how each thing related to another just yet.
Thank you very much in advance, I really do appreciate it.
