Engine idles a 3000rpm instead of 1000rpm


check for a stuck throttle body plate , also,, you have an idle control sensor, depending on which motor you have,, that could be bad, but check to see if the plate is closing properly first , remove the air cleaner tube that goes to the motor,, Look inside that part,, you'll see the plate, if its got black stuff built up on it, a couple of short blasts with some carb cleaner will remove the build up

Check engine light is on. Car has what seems to be a low idle under 1000rpm and if I floor it only goes up to 3000rpm in neutral. When I am driving along it seems to sputter as I accelerate and I can hear...


I would give you some credit for knowing the routine
when a check light comes on any vehicle,since they have
been on vehicles for 30 years. YOU GIVE US THE CODE
SET, WHEN THE LIGHT CAME ON

The idle should be around 700 rpm approx,so what is the
issue there?
The 3000 rpm is all it will go in neutral, so you don't damage
the engine,the manufacture knew you would try that!

The LS has about 2 ignition coil failures a year
All Fords loose EGR Valves early in their life
O2 Sensors get replaced at 100,000 miles
(front 2 only)

I could keep going

You just need to start working on the vehicle
instead of driving it, until it acts up

Engine dies / cuts out when cold


Check the coolant temperature sensor. It is situated in the inlet manifold at the back of the engine bay. This basically acts like an automatic choke and tells the ECU to increase fuel mixture when the engine is cold.  I replaced many many of these to Renaults, Peugeots and Citroens for this exact fault.

My 1999 v6 camry is idling way to fast 1000rpm when hot


i would start with checking the spark plug cables in some cases if there is a bad wire it can cause a irratic or high idle being a 96 it is probably fuel injected so i would check the throttle cable and throttle body it may need some cleaning or a sensor may be off such as the idle control valve.

High idle with a/c on.


Cars are SUPPOSE to idle higher when the A/C is on...(especially 134a systems)..the idle will go up and down as the compressor cycles on and off.
