Signs of a Failing EVAP canister

The canister purge valve, also commonly referred to as the purge valve, is an important component of your Evaporative Emission Control (EVAP) system. This system restricts the fuel vapours created in your fuel tank from escaping into the atmosphere by trapping them in a charcoal canister. When your engine begins to run at regular speed, the EVAP system slowly allows these vapours to be released into your engine, which burn like regular fuel. The flow of these vapours is controlled by your canister purge valve, which regulates when and how much of these vapours enter your engine. The canister purge valve is electrically operated, and is also referred to commonly as a solenoid. The most common purge valve issues are when the purge valve is stuck open or closed, or does not open at the proper time. The symptoms are listed below that may indicate your canister purge valve is not functioning properly. 1. Check Engine Light Is On The first sign of trouble for your canister purge valve is the

What To do If my car is jerking or goes off Everytime

That time you're almost ready for that important meeting, when that club is hot, when you are almost late for that important appointment, this car has started again. The car you've spent alot of money just for servicing a while ago. You're just confused!!!

Don't worry, let's check out may be we'll find some tips  here. This article covers some tips on the reasons cars go off, what follows every reason is the solution. Let's check out if you'll see something of help here.

My Car goes off while in traffic

This  happens when there's heavy traffic congestion, this fault is common with Toyota Engines.

 The idle speed continue to drop to as low as 300rpm till the vehicles eventually goes off . But after the  traffic congestion, it'll drive normal as if nothing happens to it. 

This is mostly caused by clogged (dirty) throttle body (the actuator) or blocked air filter element. 

With soft rag and paint thinner, clean thoroughly the actuator. If the air filter element is blocked, replace it with new one.

 What you just did above will solve the the problem. 

But what if your car has a manual throttle body?

If the vehicle is manual transmission (manual throttle body), then
 remove the actuator, clean the idle speed control valve or get an experienced mechanic to help you out. Thaty ome how complicated to do it without an experienced mechanic.

My Car  losses power when engaged in air condition (AC)

If you've recently worked on your AC, that involves the replacement of the compressor, check to see that, the compressor you bought is compatible with the Engine. If it's of different capacity compared to the one specified for that engine, it'll make the vibrate. This will also drop the RPM below the normal point. 

If the system of your AC is dirty, it'll be hard for condenser to reject heat, this'll make Engine to over work, then at idle, it'll drop the speed, till it eventually goes off.

The normal RPM of a healthy Engine should be 700. That's some way up between "half and one"

As you're reading this article you'll notice other  things that are the potential causes of your car tripping off.
OBDII scanning doesn't see most of this cases.

So read on

  Make sure your actuator is cleaned up for automatic. If it's manual free up the idle air control valve (IACV)

If that one doesn't solve  the problem, check the AC vacuum hose, it might be leaking pressure

My car Jerks and goes off when it hots or warms up while driving atfter few minutes: 

when at room temperature, everything seems to be ok, but after some minutes of driving, it jerks and goes off instantaneously. In this kind  of situation,  OBDII can point to many things, none of it will work. This makes some people waste alot money replacing parts after parts. See the  what you'll do below

This is the problem of fuel system. Check the pressure of the fuel pump. When replacing that fuel pump, make sure you replace it with its filter completely. 

Don't buy any how fuel pump in this condition, if you can't afford the original pump, look for a fairly used (Tokumbo) fuel pump of an engine of higher capacity than your own. Buy  it completely with the filter. 

If this this doesn't solve it, you need to call me. Yes! Call me, I'm your friend. So that we'll work it together 

Use that opportunity to service the injector nozzles, cleaned or replace the plugs if it's necessary. Everything will be fine after that, if it's from the fuel system

My Car losses power when cold, but while pressing accelerator for few minutes everything will be fine.

Your Actuator might be completely blocked.
This at times happens if the throttle body itself is faulty, then it needs replacement
 Plug in your OBDII, it'll help you out in this case.

My car is slow to pick. At first I need to be gentle with it. But when it finally picks up, I'll move fine. 

When you're having a low fuel pressure, that situation usually occur. The nozzles don't open well. In Engineering, we call it 'Lean burning', a situation where air supplied is more than fuel.

 If it lingers too much, it can result to detonation, because sparking is no longer equal to fuel supply for a stoichiometric (complete) burning. The symptom is burning ( over firing) of the spark plugs. Overheating may occur  if your cooling system is not too ok.

Replace the fuel pump with filter, service those nozzles. Replace those Sparks plugs as they might be affected due to excessive heating.
