Hi this sounds like the carbs are out of ballance, the air fuel mix is not correct and does need adjusting, check the idle screw as sometimes this will have the same affect if it is not correctly adjusted, but this does sound like you are getting to much air into the system , when you are reving the motor when it hits 1000 rpm, and you let go of the throltle does it take its time to come down? or does it drop straight away, then needs to die?, if it is the first one it is to much air, if it is the second one it is to much fuel...hope this helps

2002 kawasaki VN 750 Vulcan hard to start when cold


Hi, Gd2bbahun I would take it back to the dealer and have them fix it properly or ask for a refund and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Vacuum line from the petcock to intake manifold cracked.
5. Float needle and seat sticking.
6. Float level too low.
7. Carburetor bowl vent line clogged/blocked/pinched.
8. Idle adjusting screw set too low.
9. Air/fuel mixture screw set too lean.
10. Idle port, transfer ports, slow air jet clogged.
11. Slow fuel jet clogged.
12. Faulty fuel pump.

RPM's will not stay at a steady pace


have you thought about the idle air control (iac) or T.p.s sensor try unpluging the Iac see what happens. Just a thought also listen for a vacum leak

1996 VW Jetta with 2.0 engine. Dies when slowing from high RPM


Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

Idle Speed dies


I have a 1995 Mazada 626 V6 and i had a simular problem. My mechanic couldn't figure it out. My boyfriend did the usual checks also, but 1 thing extra he raised the idle to 1100-1200 rpm's from the 750-1000 it was at...well since then no problem.
good luck
