My1998 Mazda B3000 4x4 3.0 5 speed idles high almost all the time. It gets worse when coming to a stop and then will idle down. Sometimes it wil rev up to almost 2800 RPM. Avg. idle speed is 900 RPM.

Why does my car sometimes idle high with the clutch engaged but return to normal when vehicle comes to a stop?

The TPS can play funny tricks like this. Also sounds like a throtle linkage problem as well. Do u mean disengaged rather than engaged?

Still Rough Idle After Battery Disconnect

The first thing to do is not set up the idle speed, but to set the Idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out.

The battery has nothing to do with the idle speed

Rough idle

if its petrol, its going to be the idle speed or stepper motor ,just also check the air flow meter ,make sure there is no rubbish in the mesh in there ,,there is also a tiny little skinny wire in there ,make sure its in one piece ,dont touch it with your hands just use lite compressed air to blow it clean

How to fix this problem?

A big vacuum leak will do this it can be from a open PCV valve sticking open EGR valve to a sticking a IAC (idle air control valve) sticking open. You basically have something get stuck and closing.

I'm having a rev problem on my mazda tribute 2006. When I hit the brakes to slow down, it does it but afterwards, when I let go of the brakes, the engine revs up and accelerates even if I haven't stepped...

could possibly be the tps,or the isc,have someone check both.thats's throttle postion sensor and idle speed sensor.

Revs drop coming to standstill

Here is the cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Engine high rev at stop and slowly goes to idle speed.

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

This sounds like the TPS. Thottle Position Sensor. This controls the idle. Your local Advance Auto Parts should have this part. It should not be that expensive.
