i am having an issue right now wih my car.
i had one of those shitty ssautocrack manifold and it kept cracking so i got a drag manifold . well when i switch it out my down pipe didn’t line up right so i had to use a friends that was pretty much just dumping straight down so i had no o2 sensor hooked up. well when i was done putting the new manifold on i went to tak it for a test drive and the shit started sputtering at 4500 which is where my vtec come on at. a few of my friends suggested it could be my spark plugs so i replace those and it did nothing still same crap . then they said my spark plugs wires . so i replaced those still same crap. then they said maybe ignition coil so i hook all my msd stuff up , same crap . i have no clue what to try now. i am open for suggestions ,
when i start the car in the mourning and make a pass before car gets to 180 degrees i can go through the gears with no sputtering but one it hits 180 it sputters. :bang:
