ej6swap Posted August 31, 2009 Share Posted August 31, 2009 my 98 civic hatch with a b18a swap runs fine but when i try to rev it higher it just bogs at 3000 rpm and drops then rises up again my brotther and i have already tried checking the map sensor to the tps sensor and the ecu. i even went as far as changing three tps sensors and taking out my whole engine harness to check and see if there is any cuts on the harness but there was none either short on the money so don't want to spend anymore for miscellanous parts need to know asap. if anyone can help me with this that would be great.
