Why does the engine revs drop too low and sometimes stalling when I engage any gear?


This can be either an engine management issue (bad idle air control) or a transmission issue if an automatic trans (torque converter lock up problem). Idle air control can often be cleaned so = cheap fix. Trans problem not so easy.

My mazda drifter 2.5 D don't rev over 3000 rpm and don't go over 120 km when its in 5th gear,its like limiting.What can it be it never did it?


When you rev the engine and does not go over 3000 rpm is this in neutral or when driving in gear? Some vehicles have a rev limiter to not allow rpm over certain point when in neutral gear but is typically not limited when driving vehicle. This sounds like a very low rev limit but not abnormal if you can get engine to rev higher when driving. You call a drifter so truck must be non US market. Is this engine a 2.5 liter diesel 4 cylinder motor. Might just be your top rev and speed if this is the case.

My Vw at low revs under load in 4th 5th and 6th have a Jerk when I floor it. If anyone can assist? Thanks


What do you mean by low revs?

Under 1.5k rpm, the engine will not be generating enough torque in those gears.

Gear changes should occur between 2.5k and 3k rpm for a smoother transition.

It has been doing great but one day last week I drove it down the road and at 30mpg it started shuddering, it stopped at 35 and does great at highway speeds?? Help me please!!! Jan


If it's automatic it may not be selecting lower gear at lower revs.
other possibility is the engine management light is coming on.this is a yellow car icon on the sash.if this does come on then the car automatically goes into limp mode where it can't go faster than 30 mph to protect the engine.all sorts of reasons for it doing this low oil ....low oil pressure ....low brake fluid etc.get it to a garage and let then check ecu for any fault codes.but it does sound transmission related whereby the gears are fine when the revs are up but once you ease off accelerator it dies suggesting gears not dropping to lower gear or vacuum leak.
