i disconneted i neg on the batt to install the max 5 wire grounding kit ,borla td exhuast and kinetix h/f cats and plenum and everything went smooth in regards to the install but my service engine light is on now and i took the car for a 100 mile ride hoping it would go off with no luck any one else have this
problem and if so how can i solve it?

 

Neg battery cable off and pump the brake until the system is drained, or leave the Neg cable off for 24 hours. I would bet that your cats are causing the light.

 

I cleaned my pop charger today and forgot to connect the maf sensor, after connection the ses light stayed on, disconetcing the battery did NOT help, go here you might need to do it a few times but it worked http://technosquareinc.com/350reset.htm saved me a trip to the dealer. thanks techno

 

sorry dont the forget the www.

 

Engine Check light doesn't switch off before the dealer sets it back!
