Ok, as of this moring. When I put my car in gear, my rpm start to jumb from 900 to about 1500 and back down to 900. This only happen when i'm in gear. When i'm in nutral, it's perfectlly normal.
Can anyone help me with this new issue. I'm try to search but nothing about ruff idle when in gear.

What gear are you in and what are you doing with the clutch when this is happening?

I'm confused about this idling in gear thing. You don't idle in first. and at 900 rpm, you'd be lugging the engine something terrrible.

It sounds like it may be time for a clutch.

when you about to get the car to start moving. You have to put the car in 1st gear while you have the cluch press down, then you apply the gas and you guys know the rest.
Well when I have my car in fist gear wit the gas press down. The rpm start to jumb from 900-1500. I'll go from 900 to 1500 and stay there about 2 sec. then drop back down to 900. it never happen befor. The car run fine. When I have the car in nutral, it idle fine @ 900.
hope I clear my question up a little. Thanks any ways for you'll input.
