Specials: 10% off on fuel injection cleaning services featuring BG and Snap on products.
Fuel injection cleaning can improve performance and increase fuel economy. The process also helps reduce carbon deposits which can form on pistons, combustion chambers, valves and can clog EGR valves and system components.
Deposits in the injectors will restrct the flow of fuel causing a lean condition. the computer fuel control system has some ability to make fuel quantity adjustments to help compensate for this but it is limited and cannot correct for one or two injectors that are restricted enough to cause misfire or an unstable idle.
Intake valve deposites can trap fuel that is injected into the air stream, causing rough idle/misfire, lack of performance, higher emissions and set a check engine light. a high number of drivability issues can be improved and prevented by performing a fuel injection cleaning sevice.
These deposits are mainly due to the engines crankcase ventilation system, PCV. this system captures and recovers engine crankcase pressure leftover from combustion, and the pressure of the reciprocation of the rotating assembley. it is a closed system. oil residue and particles are part of this mix. this pressure is made up of inert gas and hydrocarbons from motor oil and combustion pressure which has blown past the piston rings, these hydrocarbons are what make up the deposits that form on the intake valves. not only do these deposits capture fuel, they also restrict and interrupt the flow of air into the combustion chamber. these deposits are only compounded by the fuel that is trapped in them. the intake system has been designed to maximize airflow to the combustion chamber, so when valve deposits interrupt the flow, performance will be lost due to improperly mixed air and fuel.
It is alway a good practice, and manditory with some cleaning solutions, to do an oil and filter change after performing a fuel injection service. solvents and detergents in the cleaning chemicals can end up in the engines crankcase and cause oil delution, and there are even some cleaning solutions that can effect the engine bearing surfaces and cause failure.
Fleet Service Northwest uses only those products approved by the Manufacturer such as Castrol lubricants,BG cleaning solutions and Genuine Land Rover parts.
As you can see, a properly performed fuel injection service is much more than just another service, it is essential to maintain peak perfromance, reduced emissions and maximum fuel efficiency.
Diagnosing a Land Rover Vehicle
The engine management system on a Land Rover can be accessed through what is called generic OBD2 with most any OBD2 scan tool. the information that is available in OBD2 is very limited. it does not give you access to manufacturer specific diagnostic codes or any of the proprietary systems, most of which are inter-related to the engine management module(ECM) via the CAN bus lines. these seperate computers, or modules as they are called, communicate data between them, for instance not only does the engine managment computer need to know vehicle speed, but the Transmission, anti-lock brake and in most cases the body control and other modules use this information as well.
Understanding the relationship between these modules is crucial to making an accurate diagnosis when taking on a drivability concern. even a no start can be confusing without a scan tool which can access these manufacturer specific DTC's. having access to wiring diagrams and factory service information is mandatory on a Land Rover.
Case studies
2000 Discovery, 4.0L
Vehicle would stall on occasion during commute, finally would not start one morning. Owner attempted to start it until battery was drained. It was towed in as a no start. We found battery completely drained. we then charged the battery, it still would not start. scanned for codes and due to the dead battery there were none present at that point. found no fuel pressure, tested fuel pump relay and pump. no power to pump or relay. there was also no spark or fuel injector voltage pulse. checked security syncronization, key fob, etc, all working properly.
All of these checks took only a very short time to complete, it could have taken us on an even wilder expedition of wasted diagnostics, and perhaps even wasted parts replacement.
The next check was to look at the scope voltage patteren of the Crankshaft position sensor. there was no signal to be found, a quick resitance check of the sensor revealed a fully open circuit in the sensor. we applied heat directly to the sensor with a heat gun while monitoring the resistance and after a little heat the resistance came into spec. the vehicle then started after a short attempt. we knew we needed to replace the sensor but wanted to do a few more test's and discuss some theory as to why this vehicle had no power to the fuel pump relay.
After a short test drive it set a cranshaft position sensor malfunction code. had the battery not been dead there is a good chance this code would have been in the ECU's memory when the vehicle arrived. this would have certainly made diagnosis much easier and faster. we would have simply tested the sensor and it's circuits, found the failed sensor and replaced it. the benefit of this type of issue is that we were able to learn something about this system that cannot be found anywhere, not even in the factory service information.
What led us to the crank position sensor? experience. having seen this issue before, we were able to do a few preliminary checks on a few circuits to eliminate them, and find the problem straight away.
It is far more cost effective for the customer to bring their particular make of vehicle to someone who specializes in that brand and has the experience and knowledge to efficiently diagnose any issues. Land Rover is one of the most challenging of all brands to diagnose. even the earlier, 1996-98 models of range rover, discovery and defender can be a challenge at times. having access to all the vehicles modules and being able to perform all module programming and coding is essential to making an accurate diagnosis and cost effective repair.
Many of the issues on todays Land Rover are either a software issue, or wiring issue. since 2005 these systems have become exponentially more reliable in the mechanical sense, it is not often we see many mechanical failures on a properly maintained vehicle in fact, I expect it is possible to get two or three hundred thousand miles out of a well maintained late model Land Rover.
Proper Maintenance
Proper maintenance will:
*increase fuel economy*
*reduce emissions*
*improve performance*
*increase reliability*
*extend vehicle service life*
Check engine light on?
If you have an illuminated check engine light, and there are no drivability concerns, look at the gas cap. Make sure the rubber seal on the underside makes full contact with the filler neck flange.
We find many caps that no longer thread into the filler neck properly. This causes a leak in the vehicle's EVAP system and will turn on the Check Engine light. This can usually be repaired easily with a new gas cap. You should only use a genuine Land Rover part for this repair.
Land Rover vehicles are the most capable on and off road vehicles on the market. They are in a class that is often imitated, but has never been duplicated. No other vehicle gives you the on road comfort you expect from any luxury vehicle, and at the same time, gives you an off road capability that is unequaled. It gives you the very best of both worlds, the traction and stability control systems on your Land Rover also make it one of the safest vehicles you can drive.
After owning many four wheel drive vehicles, I can say with confidence that My land rovers have been the best , no question.
Not only do we service Land Rovers at Fleet Service Northwest, we also own them as personal and company vehicles. This allows us to not only test, but to evaluate all of the products and services we offer.
