Ok I need some advice and soon, I have a B18b1 that was just rebuilt around 10,000 miles ago with Turbonetics Turbo kit. I only run 8psi and for the most part dont get on it. Well over the past few weeks I have notived that it will sometimes not want to start. The car will turn over but not start well after a few minutes the car will just start right up. Well today when I went to work I drove normal speeds the whole way not really getting into boost and I came to stop at a red light, well all of a sudden I felt the car kinda jerk and then the check engine light kicked on. So when the light turns green I took off well as soon as I got it into boost it felt like the car would cut out and back fire. Well I got it to work I opened the hood and didnt see anthing lose etc. Any ideas of whats going on or what to check....Please give me advice Thanks

 

did you check what the code was?

 

I am not sure yet I will check it on my break and post it

 

I am pretty sure its code 48 any clue to what this is

 

I looked up code 48 and its fuel supply system??? but what??? fuel pump, Injectors???

 

is it obd1 or 2? code 43 is fuel system on a obd1

 

Sorry I am dumb....obd1 its 48 which isLAF(lean Air Fuel_sensor defective circuit or unplugged...I have no clue what it is though
