Question about 1986 Volkswagen Golf

1 Answer

1986 VW Golf 8 valve - Why does my car shake @ 1200 RPM ?

The car's engine seems is very smooth below about 1200 RPM and above 1800 rpm. What would cause the vibration around that RPM? The problem stays the same if the car is in park or if you're actually driving it. This is my first VW so, I'm not sure if they just shake a alot.

It could be that your clutch/pressure plate/flywheel is maybe out of balance. i think thats about the only thing, if your engine seems fine.

Buick Lesaber, Lower then 1800rpm most time runs fine, Once in while surges high rpm's like driving fast 1900 & above rpm bucks /2100 smooth's out.


Need to take to a shop with a GM tech 2 or higher scan tool. These tools can actually display various sensor readings and voltages in real time and can be used while driving the car to recreate the issue. These are super expensive scan tools so most shops don't have them. Call around or bite the bullet and have a dealer do it. The money you spend on a correct diagnosis will be saved by not throwing random parts at it based on guess work.

Vibrations during idling


which engine.??? never post lacking engine ,here is why.
1.3 L G13B I4
1.5 L G15A I4
1.6 L G16B I4
1.8 L J18A I4
1.8 L BP-ZE I4
1.9 L XUD9 diesel I4

Ill answer in the generic and for GAS engines. only.
that is illegal RPM, the ECU regulates it to 800 all the time
that means the ECU can not regulate the RPM now, for many reasons.
and sure it vibrates too low, that is normal for all 4cylinders to do that.
no bad engine mounts never lower RPM to 600, ever.
they dont control idle speed at all.
the #1 reason for most cars to idle too low are:
1: EGR leaks, (clean it)
2: ISC stuck closed (electric idle speed acututor dirty) clean it.
3: gross misfiring , caused by bad spark or bad fuel mix.
4: low compression on 1 or more cylinders (real low) Do compression test at WOT. throttle.

2004 ford freestar 3.9 engine is rough vibration at about 1000 rpm, above and below 1000 rpm it runs smooth


Has the vehicle not been at a repair shop for
a couple of days, so it can be driven & the issues
figured out

All your doing is telling us the place you went can't
diagnose a vehicle

That sadly, is what we try to respond to hundreds
of times a week

When a vehicle runs rough & vibrates, you can not
come on here & say a shop can't find anything wrong,
when you can

The vehicle has to be properly diagnosed

We can't guess & you won't understand any
solutions or be in a position to tell a shop how
to do their job

Rattling noise sportage 2008


Sorry for the late reply but, no, it is not related to a loose heat shield. It is a louder rattling sound more like a loose bearing vibrating inside either the transmission or the clutch assembly. Only between 1600 and 1900 rpm. and it is not present under ou over these rpm. The rattle desappear when I lock the 4X4. Dealer is out of solution!!

03 Mazda Tribute's charging indicator light begins flashing on and off when engine reaches 1200 rpm and becomes contineously on at and above 1500 rpm. With engine idling or decelerating to below 1200 rpm...


It may be that the light is being tripped due to an "over voltage" condition. The faster you spin the alternator/engine the higher the voltage output of the alternator. I would test the voltage coming out of the alternator. It should be at about 14.3v or so max. If it gets into the 16v+ range when you increase the engine RPM then the voltage regulator has failed and needs to be replaced.

Where is the oil pressure sensor of vw golf 1999


The sensors are usually found on the oil filter flange housing with the oil cooler. Also there are two dynamic sensors to measure pressure below 2000 rpm and above 2000 rpm so it could warn you of pressure loss within those two ranges.
