codes P0171 and P0507....

**audipcanugo** · 03-27-2008 07:44 PM

Need some help here. I know what the codes mean but I cant locate the problem. No split hoses, etc...When I put it in park the RPMs are low (sputtering almost). Driving I get hesitation. Any ideas?

Bad Maf?

171 sounds like a bad MAF, I'll have to check on the 507

I got p5070 after reving it for a while at IDLE.

Bad MAF is one of the possibilities how do I check that?

507 just means idle is too low. Car is running lean. In park my car just sputters and acts like its about to die.

could be running lean cuz of bad maf

I got a 171 code and it was a leak in one of the vaccum hoses on the intake, not the maf.

Well I can't find a leak....maybe I'm not looking hard enough. How did you find it?

I didn't, a mechanic did, for about $105! It was toward the back in front the battery. I was in the bay when he was testing it and saw it leaking out. Part was $150-200 if I remember correctly.
