Sluggish at highway speeds
Hi. Hope y’all are good. Been having some weird issue with my car recently. Put simply, she runs. Fine. Ish. Car drives, starts, stops, no problem. No check engine light but at around 130 km/h / 80 mph, she starts having issues going faster. Well. Not 130 and nothing more, she gains speed but enough. Used to be that you’d literally be pushed back into the seat under hard pulls but not anymore. All relays have been changed, battery is new-ish - changed in march 26 - coming close to 124,000 km. Only apparent issue when doing a quick scan via OBD with ELM327 and iPhone scanner app is U1008(00) which seems to be something with the auxiliary water pump. Trouble is, that thing still works. 2017 Giulia, 200 hp, Mauritius (so no goddamn dealer). Any suggestions please ?
