I would recommend removing the ignition lock cylinder and trying this again. Many ignition cylinders have small parts called tumblers that require being put together in an exact way. If any of these tumblers are not in their correct position,...

Hi, thanks for your question. I'd be happy to help. The diesel battery may be heavy duty compared to the petrol engine. The two batteries should be compared for size and height to be the same and the terminals should...

You will need to check the engine intake for vacuum leaks and if not then replace the sticking idle control valve and then relearn the idle by disconnecting the battery and then reconnect after 10 minutes. Start and hold at...

In your initial question, I did not know that valve damage occurred as a consequence of a failed timing belt replacement. The 4 valves that the shop "claims" were damaged might merely represent what they "think" was the extent of...

It is recommended t replace pads with the new rotors. The old rotors would of put grooves in the pads and caused them to not be flat anymore. If you decide to use the existing pads then you should sand...

A faulty or blown fuse in other electronically controlled systems can cause the IAC (idle air control) motor to malfunction, leading to a higher than normal engine idle speed. Other possible causes of a high idle include vacuum leaks, a...

Hi there, thanks for writing in. I have never experienced this exact issue before. First we should address the vacuum leak, which could cause the car to stall while idling, as well as being a potential cause of the oxygen...

Misfiring can be caused by lack of spark or lack of fuel. If the same cylinders are still showing codes for misfiring after replacing the coils, the problem can lie elsewhere. If it is the coils not firing, there can...

A failed compressor is just one of the many potential causes for your A/C being inoperative. It could be something as simple as low refrigerant level. If you are questioning your mechanic, I suggest you get a second opinion....

Hello...The vibration problem that you are having can be resolved and your question is a good first step toward resolving it. There appears to be four (4) mounts in your application. Presumably you replaced all four if you suspected the...

Ideally, you should have aligned the marks before you removed the timing belt. It sounds as though everything is completely disassembled already. This makes things a bit more difficult. I would only recommend assembling it the same way as you...

Thanks for asking. With all of the work that has been done to the vehicle, I would recommend having a mechanic, such as one of our YourMechanic experts, inspect your starting issue. Your symptoms sound like an air/fuel metering concern...

What you are describing sounds like a faulty starter solenoid. A faulty starter solenoid will generally produce a clicking sound when turning the key. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity...

Hi. If the code is still present after both sensors have been replaced, and the engine is stalling, further diagnostics is needed. First of all, a new sensor doesn’t always mean a good sensor, especially aftermarket ones. Check the sensor...

The cost to replace the engine may exceed the value of the vehicle. It will cost less to replace the engine with a used one versus overhauling the existing engine.

You may have ignition coils that are giving out a weak spark and or failing intermittently causing the misfire. Also a system that is running lean may cause random misfires. have the coils checked for spark output after engine is...
