Question about 2000 Mazda Millenia
Once accelerated to 40mph car loses acceleration & traction light comes on
This must be a 2.3 miller cycle. it is going into "limp home" mode. when this happens, it wont rev over about 3k, and tcs off/tcs lites come on. it feels a lot like fuel cut. probably the check engine lite is also on, and what codes are stored? most common is P1525/26 and 1540, which are the solenoids that control the abv. the abv controls boost, and when this valve is not working proplerly, the pcm stops communication with tcm, and it goes limp home. if you can locate the solenoids, they are on the back of the engine, right next to the egr valve. from right to left, you need to look at the second and forth. you need to ohm them when they are hot. normal is around 26. if they are over 30, or 0, they are bad. there are other possibilities, but this is most common
