Faulty Throttle Sensor in Bayswater with Robbie McQueen http://www.wolfems.com Rob talks about how a faulty throttle position sensor effects engine management and fuel injection systems.

As older cars running electronic fuel injection continue to age, these types of problems are going to occur more often and diagnosis is going to become more tricky than before.

This is not going to be a big lesson on electronic theory, but I thought a lot of you have been asking about some basic info on resistors, caps and diodes, like “what does a diode do?”
So I thought a quick look at these might help you feel a little more comfortable when dealing with them.

If you imagine a huge fuel pump. It pumps a huge volume of fuel. That fuel travels along a fuel line, some of it is used by the fuel injectors, and then it comes to the fuel pressure regulator. The only problem is that the fittings and internal galleries on this fuel pressure regulator are much smaller than the fuel line and fuel rail, and so the regulator cannot regulate the fuel pressure down to where it needs to be.

What can dirty injectors do to your engine?
Cause Idle Problems – misfires at idle, lumpy idle, inconsistent idle speed.

We all know that increasing fuel pressure means you get more fuel per squirt right?
Well that may be true, to a point.

Most of us know that you cannot begin to even try to start an engine without a timing light (although many have tried in the past – including myself in my early days). But, without knowing that your ECU is delivering the ignition timing that you think it is delivering, at best you can guess what the real ignition timing is, and at worst you can potentially cause damage to your engine.

This posts subject line is “General Fault Finding Mindset”, and that may sound a little dry to some of you, but what I’m trying to get across is that when you are installing and EFI system (or any automotive electronics for that matter), there are a few simple things you can do to speed up the diagnosis when there appears to be a problem.
