Hello I am new here I have a 1997 MX6 2.5 V6 I recently installed a timing belt the engine runs smooth but very predictably when the engine is at full heat it will buck very hard approximately 3200 rpm every time. The car does not want to surpass those rpm. But when the engine is cold it can rev too close to 6000 smoothly. This makes acceleration almost dangerous as the engine almost stalls until i back off the gas and drop below 3200 -3500. I thought maybe injector fuel pressure regulator. Any advice?
