- THIS IS A FEW TIPS ON RUNNING HEADERS ON A 1997 CHEVY TAHOE 5.7L VORTEC V-8 PROTECTING PLUG WIRES WITH HEAT RESISTANT BOOTS. HEADER WRAP IS A MUST!
Man I'm having horrible problems with mine! I have a 97 Z71 5.7 Vortec. Just installed long tube headers and header mufflers and now the damn thing will hardly run!
In order to start it I have to smash the throttle wide open and then when it does start it loads up horribly.
I was told I could just drill out a hole near the collectors for my first set of O2 sensors but I didn't need to worry about the two downstream sensors??
It will definitely run terrible if you don’t have your O2 sensors hooked up. On those trucks, the second one farther back is known as the downstream O2 that’s not as important but upstream the first one is. Just weld em in and you’ll be set. You can get weld in O2 bungs (threads) online cheap. I like the ones that have a step in them. It gives you a little more surface to weld to.
Thanks fir watchin!
@@unclelemme Thanks for responding, I appreciate it! I will definitely buy the threaded bungs as you suggested, but do you think the other way is just as effective? He just drilled out a hole in both header's near the collectors, threaded them, then installed his old censors.
He didn't have access to a welder and he needed to get the truck out of its current location ASAP. Thanks again!
Yes you can drill em out and just thread them in. But they may leak or pop out. It’s worth a shot worst case you just weld in a new bung later. Good luck with your project, take care!
