1997 Buick Park Avenue Ultra 3.8 L SC with code p0171

Question

Hi Reynaldo

I cleared error code, after that say about half hour car run fine and then out of blues Anti-lock and traction control light was on dash board and two minutes later SES light is on. I checked and back to code 'p0171' but shut the engine off waited for ten minutes, started the engine SES light is on but no anti-lock and traction control light is gone.

Thanks in advance

When you disconnect the MAF, the MAP takes over, If you disconnect the MAF and only P0102 is there and no P0171 then the problem is with the MAF sensor, I know you say its new, but new doesnt mean its good.MAF code P0102 is a type "A" code which means ABS and traction are disabled,
