Car start and the moment gas paddle or chnge the gear car shut off. Local mechanic could not solve the problem, what are the options

I really like your thouroness although,have you inspected the fuel pump function and output? marcus

Your best bet , take it to a qualified repair shop an have diagnostics done , the right way ! No guessing .

048 Engine Hard to Start or No Start Scan Data for Starting Problems

I suggest you get one of those manuals people get nowadays
to do it yourself.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from.

I would pay more attention to the air flow sensor and mass air flow sensor, putting this on a diagnostic machine will pinpoint the errors stored on the onboard computer. both sensors can be cleaned by a competent mechanic, most mechanics don't want to, they prefer just to swap items out these days because of costs. get a reading, then you will know for sure. good luck.

Usually a sign of a faulty throttle position sensor or low fuel pressure.
Those two things would need to be checked first.

ask a local mechanic to check engine mountings for you

Replace just the TPS Sensor (throttle position),
not the entire throttle body, as you may have been told

Educate Yourself

Be careful,you will be sold something
you don't need

have you checked the fuel filter,it may be slightly shoked so allows for light thottle but not enough for full thottle, {we had a 405 ,towing a caravan,only power for 1st gear,very embarising.}

its because its an import, buy a conversion plate for your dash and a new radio

did u check the throttle position sensor
