I put in headers a couple months ago and the service engine soon light was on and it scanned MAF system failure. I swapped MAFs and nothing. I figured out that it was Fuse #10 in the engine bay. I changed it... all was well for about 3 weeks. Then the fuse blew again... changed it... all was well for about 2 weeks... changed the fuse again and now it blows within like 5 minutes of driving... especially if I get on it. I cleaned my MAF sensor and K&N filter... what's going on anyone ever have this problem??

 

BTW i have a 96 z28 with OBDI conversion... headers, no cats, roller rockers, CAI, catback, A4 with 3500 stall verter....

 

Since that sensor also powers the O2 sensors, I bet you have burnt wire that is grounding out on a header. That's a pretty common occurance with headers.

 

Thanks a lot Shoebox. I'll check it out when I get home tonight! I'll post up the results as soon as I know.
