Car starts just fine but when i try to go or rev the engine it stops at 2000 rpm is this some kind of sensor.

u may need ur ecu reset also have a comprestion test done on it it may have a broke piston ring

how to stop a Chevy Tahoe from misfiring and smelling gas

The vibrating sound is probably your heat shield on your exhaust,as you rev the engine the vibration is amplified and may be tripping your knock sensor, try removing the heat shield and see what happens.

make sure you have the wires in the right places. (see pic)
Make sure you did not leave something unplugged. (sensor/vacuum line)

check high tension lead from coil to distributor and distributor rotor voltige or fuel not reach the pistons,notes2000 rpm you have this stop the car engine on rev 2000 rpm and spray your filter with engine start same time exalaraite to high revs and se the risults.good luck.

Sounds like a coolant sensor problem. It signals the ECU for open loop, cold start rich, high idle, until warm up is reached.

We are having the same problem. We are right now changing the crankshaft position sensor along with the intake and manifold gaskets.

Am not shure the kind of engin you really have but see if your stepping mottor is damage or need relpacing. that problem can happen if you have a faulty unit . it also called the step up unit or sensor, if your car have air condition is turned on and the rpm goes up and down that can be the problem , the unit can be found attached to the throttle body. just below.

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

What you need is a "revolution sensor" I had the same exact problem. Replaced the sensor and everything is fine
