Chinese are going to take over the automobile industry for sure. Tesla who was considered ground braking is shying away from the promised small EV and moving to Taxi cars as the competition is too strong. Then comes Chery with this small EV SUV. Looks like a Mini G Class / Jimny but is fully electric.· 4 replies

Interior Specialists? Every time I go over some bumps my seats squeak quite loudly and there is a massive rattle of a nail undone coming from inside the dashboard, anybody got any suggestions I could go to? My usual mechanic just said "turn the radio up"· 2 replies

I was watching a Yangwang U8 struggling to make it up a muddy hill on Youtube. I was wondering why cant an EV be more capable off road than an ICE vehicle. Given the fact that this behemoth has 4 individual motor on each wheel it should be able to direct power to the wheel that has more grip and stop power to the slipping wheel. Cant be rocket science right?· 3 replies

I woke up one day and I now want to buy a W140. The brain works in mysterious ways. It definitely doesn't understand the concept of money since I am nowhere near affording one.· 2 replies

Question
Ted
Dear All,
I failed my emission test even after injector cleaning. Then i went to an ECU guy and what he did first was replacing O2 sensor. After than CO emission was 4.8 which is not acceptable. Then in order to improve the CO emission further, he modified MAP sensor by adding resistors in between map sensor and ECU. Then CO emission was 0.029%.
However when i drive a steep hill road eg. Galagedara steep, i cannot pick up the car even after i peddle the engine to very high rpms ( 4000 - 4500).
What i want to know is by modifying MAP in addition to improve CO emission and make the car fuel economy, does the acceleration capacity of the car reduce??
If so could you please let me know of a skilled genuine guy who does not these kind of modification but does as per maintenance instructions recommended by toyota?
Thanks..
