My Buick had the same problem and it was simply a stuck damper, behind the glove compartment. Freed it up, simple fix, works fine now.

SOURCE: santro car is having rough noise from engine. done 78000 kms on

Hi. if your timeing belt has not been changed that would be the noise it will make. you should get done right away because if that belt breaks you motor will need a new top end. I hear them all the time when the belt is getting to go and the way you explained it. It sounds like you need one today. It will cost you about 500. hope i was a help to you and good luck. P.S. change that belt every 60,000 miles.

How to fix code 12 on toyota conquest 1994 model

Hi there:
Means that there is no RPM signal going from the distributor to the ECU (Engine Control Unit). You probably can't get your engine to run.

Possible causes are:
- No signal from NE or G to the igniter
- No signal from the igniter to the ECU
- Faulty ECU
- Open in igniter to ECU signal circuits
- Loss of power or ground to the igniter

If you can hear that the starter motor is turning without turning the engine, most likely your solenoid has gone bad, or there's a bad connection somewhere.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My car has 12,000 miles and my engine light came on?

Hello! The Check Engine Light (CEL) is the vehicle's Electronic Control Unit (ECU) telling you it has found and stored a fault...These faults are handled by On Board Diagnostics Version II (OBDII)...Take your MPV to an auto parts store and they will decode the fault as a courtesy...Typical faults begin with a letter "P" followed by four digits (P0402 as an example)...That code tells a technician what area or circuit is at fault...When you have the code, send a comment and I'll FixYa...................Guru.....saailer

Hi, We have a Kia Sedona and the orange light on the dashboard, that looks like a coil keeps flickering when driving - could you please tell me what the problem could be? Many Thanks

Dear Madam or Sir,

If the "Check Engine Light" comes up, the on board diagnosis system of your vehicle has detected an error with the petrol injection system, a faulty sensor, stuck servo motor etc. for example.

The light indicates the recognition and storage of an digital trouble code to the system´s memory to the driver. You should see a mechanic to check the ECU (engine control unit) for saved trouble codes.

Please don´t hesitate too long to prevent the engine from serious damage.

Kind regards from Germany

I have a 1997 328 ic that has a check engine light on I bought a code reader but all it tells me is the code and the problem I don't know how to fix it the codes are 41 camshaft sensor and f-6 which is...

check for a wet ecu

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other

all the way to engine failure and worst case burnt and shorted wiring

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.
