I have a '99 b18b turbo. I went on a 13 hour road trip to spend a week with my family and when i got back my engine check light went on and my car was burning fuel hella lean. i have the fuel gauge thing and it would just stay at lean. My car gets jacked and i just got it back with almost nothing taken out of the motor except the dizzy. I just started it again and the engine check light is on and stills burn lean. Can someone help me out?

 

Get a scan tool asap and run it for PID's. You'll probably be seein a lean code but you never know. I just wouldnt reccomend driving your car much cuz you could melt down your internals. Sorry i cant be more help, bump for more options.

 

Thanks. anyone else with any opinions?

 

maybe a bad 02 sensor, check the code

 

how do i check the code?

 

just go to a local autozone, they will scan it for free

 

sounds like a sensor problem, like maybe o2 sensor and ur car is pulling the wrong A/F maps from incorrect readings from the sensor.

 

Also check your vacuum line on your FPR.

 

Thanks guys

 

Yeah, Im gonna go ahead and say it's the o2 sensor. The other kid was probably right with the A/F maps. They are probably being thrown off by the faulty o2 sensor.
