Need help please! I have a certain car (someday it will be a Porsche) with D-jet, rebuilt manifold air pressure sensor, new injectors, new fuel pressure regulator, and a new PC board in the Throttle Position Switch. While cruising, I get a hesitation (pretty severe) that feels like some is flipping a switch off/on. Wondering if anyone can give me an idea what might be wrong? I hope my terminology is OK..and I searched but no results...
Thanks for any help. |
