SOURCE: 96 lincoln town car- loud humming noise

I had experienced the same problem with my 93 TC. I'll try to make it short. Replace the Idle Control Valve. Cost me $50 at AutoZone. It has a electronic plunger that has a rubber o ring on the end of it. It separates two air chambers inside the valve. When the rubber gets old and the plunger is suppose to cut off the air coming in from one chamber to the other, the air gets sucked between the chambers across the old rubber causing the humming noise. That is also why the engines revs up and down and wont idle right. It is located between the firewall and the back of the motor just to the left (drivers side) of the throttle control assembly. When you look up on the internet on how to replace it, it will tell you to remove all the housing surrounding the wiper blade control arms and assembly so that you can access it. If you take your time, just remove some of the hoses and wires connected around it and you can access it without removing all that ****. Only has two screws to it that point up and can be reached with a ratchet and extension. Car runs great now and finally got rid of that noise.

SOURCE: my 2000 lincoln towncar heater blower motor only

This could be bad electrical connection at the motor, bad bearings or bad motor armature. Tapping the motor with a rubber mallet will sometimes get the motor started. I've used the mallet for two different motors and it works until the motor finally goes bad.

Why does my engine not rev. above 3000 rpm in park?


It's made that way. It is a limiter built into the PCM.

My mazda drifter 2.5 D don't rev over 3000 rpm and don't go over 120 km when its in 5th gear,its like limiting pulling back.What can it be it never did it?I use to push it 160 km @ 5000 rpm before


So it did rev higher and go faster before i see. 160kph equates to almost 100 mph!!! In that truck?? You nuts!! I put my Mazda Millenia supercharged V6 to 140mph in Nevada but that was on straight roads with no curves in site for miles ahead. Haha. Ask again if this is a diesel motor in truck. That sounds like getting close to limit of capacity of engine but if more was expected and received before then would look at an exhaust restriction first. Do you have catalytic converters on the truck?

When you rev the engine and does not go over 3000 rpm is this in neutral or when driving in gear? Some vehicles have a rev limiter to not allow rpm over certain point when in neutral gear but is typically not limited when driving vehicle. This sounds like a very low rev limit but not abnormal if you can get engine to rev higher when driving. You call a drifter so truck must be non US market. Is this engine a 2.5 liter diesel 4 cylinder motor. Might just be your top rev and speed if this is the case.

My grang cherokee2002 us spec, while driving trnz changes fine but when cick down or full excelrate and RPM reaches 4.5 or 5 engine is loosing power and getting noisy and RPM not going more, while gear on...


You are hitting the rev limiter top range, which cuts off your ignition.

I have a 2001 Grand Cherokee and the problem drives me crazy, but it is the way the car is designed- as soon as you hit the rev limit, it shuts down ignition and your jeep will "buck" - a real pain when you are trying to accelerate into traffic!

You have the 4.0L straight six engine, yes?

If so, please take my advice and learn to live with the minor annoyance of the rev limiter- that engine is IMHO the best Chrysler ever made (nearly "bulletproof"!) and it was so reliable you cannot even get it in a jeep now! For decades, that engine was used in welders, tractors, generators...and yes, jeeps... and it is a favorite among mechanics for its durability!

Have 1999 cavilleir does it have a rpm protecter


Yes, the PCM for your vehicle's engine has a rev/speed limit seeting programmed into it. Most stock, non high performance/police package vehicles usually won't go above a top speed of 97MPH. if you were to rev your engine while it was in park or neutral, once the engine reaches the cut out rpm limit preset in the PCM, it will cause the engine to cut back, then it will rev up until it hits the preset limit, then cut back, and it keep repeating that pattern. It may sound as though you have a high rev ignition failure that sounds like waaa, waaa, waaa, waaa, but that indicates the PCM is doing its job.

I have 2000 V8 LS thatruns rough in park and at idle in drive.


That is normal.
If you rev it in park it will not rev over 3500 rpm before it hits the rev limiter.
