Well after doing some more research. theres a couple of things left i can think of.im debating on using sea foam in the tank, vacuum line, and crankcase next oil change
The pipe that i need to replace is pipe B the resonator system.found one online for 100$ with free shipping.not sure but would a hole in that area cause hesitation like im having? An engineer at my workplace might be able to weld the pipe on for me cheaper than a shop.if this doesnt do it i will probably attempt to sea foam the system.
Iv also read about cleaning the egr ports as well.on my crx they were welded.on this one though there are caps over the hole areas.is there someway to get them out?
