Check engine light! P1093

FoxBlvd · 06-27-2012, 02:17 PM

Hi, I recently changed out my pulleys and tensional with regards to the (WP, PS, Alt). A few days later, my check engine light displayed on my dash. I scanned the code, and found it to be P1093 with the generic code scanner and Table 19: EC (PreCat fuel tim system, Cyl 4-6) with my Peake Scanner.
History:
A couple of months before, my car displayed a different code that required a software update. Also, I have replaced all my o2 sensors (Pre and Post), as well as changed the oil separator. Also my intake boot looks fine too.

Thanks!

Fixed this by unplugging the MAF and the DISA connections. NOT sure how they are related... but it worked!

Not likely your O2 sensors!

Need to think before you do!
