    Not sure what posting was supposed to say, but I take it your experiencing vibration. Does it vibrate when sitting in park, at idle, or revving engine? Only vibrate at certain speeds, or all the time while accelerating or slowing down?

Feel it throughout van, or just up front? Tire balance has been checked? That is rear wheel drive correct?

    Did you have vibration before new tires?

    On the 95' try feeling hoses going into firewall, to heater core, they should both feel close to same temperature when heater on.

    I would have tire balance re-checked and U- joints checked on the 2002. On the 95' I would check the blend air door and actuator under dash for perhaps a vacuum leak, or malfunction.

Hi, my car starts vibrating at 2800 RPM and vibrations dissapears at 3000 RPM.


does it have the same acceleration at that speed, if it does not accelerate so well it is called a flat spot and will almost certainly need a good mechanic to sort it out
If acceleration remains as good in this range as through the rest of the rev ange add detail and please resubmit

04 acura ti 3.2 litre engine vibration from idle to 1500 rpm


Wow thats a bunch of miles for only 9 yrs.
I would want to know if it is something related to the engine or transmission, or the wheels and suspension.
Does it happen in all gears, and at any road speed ? Can you rev up the engine and make the vibration, or does the car have to be moving ?

Car pulses and rpm fluctuates what is it?


if the car is running does it have the check engine light on? if yes what is the code if no then check to see if temp sensor is reading the right temp by plugging in a scanner that can read all data to give you an accurate reading... if it reads wrong temp it can cause running issues

2002 Mercury Cougar Squeal


Just for testing, a few seconds, will the vehicle start and run w/o the belt? Have a helper work the throttle, is the sound gone? If problem not the belt, check the belt driven accessory. Sometimes you can use a long metal rod of some kind, with belt on, one end of the rod touches accessory housing, the other end goes on that bone behind your ear, helps to magnify the sound. I guess you could use a mechanics stethoscope to do the same thing. Have helper work the throttle while you listen to each. Don't get tool or anything caught in belt. This is a serpentine belt, I haven't looked?
Maybe an accessory trying to freeze up or bad bearing? I can't think of anything else at the moment?

On cold days, temp takes miles to come up and the transmission will not shift into top gear until then. Limits speed to around 50 MPH until this happens, not wanting to run the engine at a high RPM. Today,...


Yes this sounds like a thermostat problem, replace the thermostat, Delay on transmission shift is a common problem, you could try changing transmission oil.

Won't shift into overdrive


The engine temp has nothing to do with overdrive, transmission temp may, but either way if you are just coasting it should go in, or maintaining a speed of at least 44mph it should go in. How many miles on your car? It could be a sign of worse to come, usually the highest gears go first.... 3rd or 4th gear could be next.
