Missing at 3000rpm

Very rough idling. At about 3000rpm in the park it start missing like it is starving for fuel. Will not go over 3000rpms.When driving, at 60mph(3000rpms) it rides rough. Again,starving for fuel.

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.

Cheers.

SOURCE: Checked the carb out at 0400 this morning while

a couple of places to look at would be the carb,(float bowl and needle valve)to see if it might be overloading it with fuel,the other would be the choke weather it be electric or vacume/mechanical, then look at the egr valve to see if is operating right,check the vacume on it also,if u pull a vacume on it, and it does the same thing, that it has been doing then its either going bad or there is a vacume problem.
If it is the fuel overloading it you can check the plugs to make sure,check for a black,sooty build up on them.(carbon buildup)
being as you put a new fuel pump in it it might be possible that it has blown an internal seal in the carb if its the original carb,and that would cause it to stall out till the fuel level came back down in the float bowl.

Why does my engine start bogging down when it gets to 3000rpms in park


Ford transit connect I've had experiance with the same problem turned out the turbo needs back pressure from the exhaust pipe witch was blowing/had holes in so when 3000rpm was reached it began to bog down.maybe check your exhaust system or air filter.

Hope that helps

99 ford ranger, idles rough till it warms up,then runs good. Hard to start after it gets hot, it acts as if it is starved for fuel. Once it does crank it runs fine.


First thought: Check the idle air control valve, or whatever its Ford equivalent is. Sometimes these start to stick and cause the rough early idle that smooths out later.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

just a guess but might be a fuel pump, try smacking the tank before you start it and see if it idles better after.
