Your Golf should have two fuel pumps: one for the injectors (high pressure) and one which feeds the injector pump (low pressure). The low pressure pump would reside in the fuel tank. I'm thinking the low pressure pump may be going bad, as in getting weak. If it were starting to overheat, it may not pump fuel like it is supposed to and would cause the loss of ...

You need to go back and look at the firing order of the spark plug wires you installed. If you get two out of place on a four cylinder engine, you now only have two good firing cylinders, and depending on which two got switched, one of them may even be firing the cylinder at opposition to the rest, not allowing the engine to get anywhere close to operating ...

An AC compressor puts a big strain on an engine when it's engaged. This is especially the case with low horse power 4-cylinder engines. What makes matters worse are high mileage engines which are in poor running condition. I experienced this with a Saab I used to have. I could only run the AC when I was moving at highway speeds. Otherwise it was too much ...

The slightly high idle and roughness at idle sounds like a symptom of a vacuum leak in the intake system. It also would cause it to go away when the throttle is slightly depressed taking the engine off idle (~1000RPM) Here is how you can test that theory: A common trick I used in the shop is to spray the intake area from the throttle body to the cylinder ...

I had the same problem with my car last year, problem only occurred when idling and not while driving. This is why I immediately suspected the IAC. Removing and cleaning the IAC did the trick for me. Hope this will help you.

Usually when I hear what you are describing, I put the issue at the front end of the transmission, either with the front bearing or the carrier bearing supporting the input portion of the transmission. Here is my reasoning: Your description places the noise/vibration when the transmission is engaged in neutral, which means the clutch is engaged with the ...

1) Does that diagnosis sound correct? Seafoam sounds like a good way to go, but in this case it isn't going to cure the ill. The throttle body itself needs to be cleaned. I found this video which should show you pretty much how to clean it (as long as your engine is the same as the G35 in the video). Since the engine has reusable gaskets, as long as you ...

You can actually insert programming scripts into your ECU. Palmer Performance has a variety of adapters and computer software. I know they have some kind of script library, or you could try replacing the computer. Have someone check your distributor. If it's throwing check engine codes, take off your valve cover and tighten the studs with a breaker bar but ...

I had similar problem with my car too. During the 60 000 km check my mehcanic said they had to replace the "AC belt tensioner" because it was in bad condition. It didn't cost too much, worth a try. That 'click' sound after switching on the AC means that the AC clutch engaged and yes, it could be a bit noisy and it cause a strain for low powered cars. It's ...

I fixed the vibration problem I had for 1 year on my 2007 toyota camry after I cleaned the throttle body and air control valve (iac) the car is driving perfect. I can not believe it was so easy to fix...

These motors were plagued by problematic cylinder heads. Usually the end result in cases like yours are replacement of the Cylinder Head. Most likely there is either a blown head gasket or burnt exhaust valve. If there are no vacuum leaks and MAF is good then you need you start looking deeper into the engine.
