So my truck finally started throwing code's. The cats are bad. Gutted the cats. Replaced the plugs with NGK iridium's. Took the neg battery post off while I changed the plugs. Still getting the acceleration hesitation. 02sensors maybe? And can I or how do I bypass them?
It is the V6. What's the best plugs for it? And at what gap should I run them? Intake looks clean. It idles perfect. Only get the hesitation when I accelerate from a from a stop. Acting like a vacuum issue.
Plugs where gaped at 35 I changed them to 44. There NGK was told they had just replaced them not to long ago. I was checking to see if maybe one was loose.its got 135000 miles and cold air intake. My next step was to start playing with the fuel system. To see if I can get it to smooth out.
