A scan for trouble codes may point you in the right direction quickly, rather than hit & miss, with replacing parts. Some of the autoparts stores will scan for free, and your right where you need to be to get the right part at the same time.

It's probably the mass airflow sensor and/or oxygen sensors.

SOURCE: 97 F350 diesel check engine light stays on and is running rough?

Ok, lets take this from the top. I have a 97 f250 diesel. In mid may mine did the same thing. It's either one of two things. You have under valve cover harnesses (uvc). They slide in under your valve covers, you will see two wiring harnesses on the outside of the valve cover gaskets on either side of the block. Ok, it IS possible one of these slipped out of place and killed two of your injectors, causing the horrible running/ low idle/no power/ sounds like the truck is going to stall symptoms. The easiest way to check that is to unplug the wires while the truck is running and see if it kills the engine, if it doesen't unplug the other one on the same side of the valve cover. If both of these don't cause any change then you have a bigger problem, the IDM (Injector drive module).

FAIR WARNING: When you unplug the wires with the truck on it is extremely dangerous, it is 110 volt feed. It can kill you.

OK, the IDM is a silver box, 8"x10" approx dimensions, located on the driver side under the hood, over top the front tire. If you take the wires you unplugged and take a multi meter to them and they are dead, you have a bad IDM. This was the case with my truck. Ford designed the IDM to have a hole in the side to allow condensation to escape from it, unfortunately, this allows water inside and will short out resistors and practically kill half of your engine. Buy a new IDM on ebay for about $380. It takes 5 minuts to put it in.

I hope this helps you out man.

I have 2008 chevy Impala 3.5l v6 Vin K an I have tried everything to fix the vehicle the check engine light comes on dash says engine power is reduced an runs fairly rough


Hi Christopher.
Have you tuned up the engine? Changed spark plugs, wires, and air filter? Another possibility is you may have some water in your gas and/or partially plugged fuel injectors. Pick up a bottle of fuel system cleaner with water remover at your local parts store and pour it into your gas tank on your next fill-up. If there is water in your gas and/or partially plugged injectors, you should notice a difference in engine performance in about a day or so, depending on your driving habits. Hope this helps. Let me know.

How do I clean the Plenum/Air Intake system


If you are just cleaning the throttle plate/bore, use carb cleaner in a spray can ( this will also clean some of the plenum as it is injested into the vehicle ) and remove the air intake hose from the air cleaner to the throttle bore assembly. OPen the throttle plate by hand and spray cleaner inside ( with vehicle not running ) and remove any carbon/oil deposits that are around the throttle plate. If the plate area is very dirty/black in color, you can use a toothbrush to help clean. When vehicle is started, it may run rough until all the extra cleaner is burned from the intake. If you want the entire upper system cleaned, you will require a fuel injection cleaning machine that most shops will have. The do it at home procedure as mentioned works well

Replaced Fuel filter, Plugs and wires, PCV valve and the Throttle air control valve. Still running rough. Could it be an 02 senor or the catalytic Converter? Car wants to dye out when coming to a stop or...


Hi there, i had a similar problem with my Legacy B4 RSK Blitzen, 2 litre Twin Turbo, Engine EJ208. Car would idle sort of ok when cold, after warming up it would idle erratically (idle hunting) and cut out sometimes. I notices the boost gauge hunting along with the RPM'S .I found it to be 2 faults. 1st fault - If you have an after market air filter and the car hasn't been mapped for the extra airflow past the MAF (Airflow Meter) then it confuses the ecu as its taking in un-metered air. Solution - Re-map car to take extra airflow or as i did, i took out the MAF and cleaned it with a can of Carb&Choke cleaner. It worked but still had rough idle.
2nd fault - Air could be in your cooling system. If there is air in the system then the engine temp sensor is reading hot/cold/hot/cold everytime an air bubble passes by, which will cause running problems. You may hear a gurgling or slushing noise in the car, which is air in the heater matrix. Solution - From cold open the header tank and coolant overflow bottle, un car untill engine warm and hold at 2000-4000 rpm untill you see air bubbles rise in the header tank. Make sure your hot air is turned on in the car and vents open. Do this process for 10-15 mins and when you think all air is out of system then re-fit header tank cap. Have a watering can at hand as you may require to top it up during bleeding. It will overflow but dont worry.


Only real problems Legacy's give are , Air Flow Meters, Knock sensors, and Lambda Sensors (O2 sensor). Hope this helps mate, keep us informed on how you get on.

The air mixture screw does not make my mixture richer or leaner


Unless your vehicle is really old and has a carburetor there shouldn't be an air mixture screw. Air and fuel mixture ratios on engines with Electronic Fuel Injection or EFI are controlled by the vehicle computer witch receives and sends information to and from a slew of different sensors like the oxygen sensors, throttle position sensor, the idle air control valve, Etc. Chances are you have EFI on your vehicle. If your engine is running rough or lacks power, try a complete tune up. New spark plugs/wires, new fuel filter, new air filter, oil and filter change, new oxygen sensors. Try running a bottle of injector cleaner and a bottle of water remover through the vehicle and see if it helps. Hope this helps.

Camry 1991- really sluggish and jerky


It's just going to take some time and simple cleaning. If there is an Auto Zone around your area, you can buy all the things needed to get the car running 100% again in no time at all for under $40.00. Here is a few things that I do when i get a new car with a few years under it's wheels. Buy a bottle of injector cleaner for the fuel injectors, like STP, a bottle of Marvel Mystery Oil to add to the engine oil, and two can's of Throttle body cleaner for the throttle body and follow the instructions on the can. Make sure it's throttle body cleaner. The Carburetor cleaner is to corrosive for the throttle body gasket. Once you have reached 3,000 miles, service the engine and have them replace the oil (5W-30) and filter and add another Marvel Mystery Oil. This will clean out all the carbon and sludge in the engine to free up the oil passage ways, replace the Air filter, and PVC valve every 30,000 miles or once a year. Cleaning out the throttle body and adding the fuel injector cleaner will also help the fuel system and have them replace the fuel filter every 30,000 miles or once a year to ensure there is no fuel restrictions in the fuel system. Once this has been done you will notice the engine runs like new and you may have to use the Marvel Mystery Oil and fuel injector cleaner every 6 months to keep the internal engine free from sludge and carbon. Good luck and keep me posted, be glad to help you keep the car running 100% for a long time.

Jeep turns over but will not start


I am going to assume that you didn't accidentally put DIESEL in?? If you did, siphon all you can out and add fresh GAS(!) and 3-4 bottles Octane booster.

Squirt a bit of Starting Ether in the Air CLeaner inlet
Start Jeep
Squirt Ether
Start Jeep
Start Jeep
Squirt Ether
Start Jeep
Repeat until it runs. Do not use alot of Ether - will blow engine!!!
Fixed!

If you didn't put Diesel in, and KNOWING that the problems are usually FIRE-related, replace all FIRE-related parts ($40.00)

Get new ROTOR (Thingy that spins inside CAP, distributes HVolts)
Get new CAP
Get new cables (change cables to new CAP 1 at a time!!!) DO NOT RUN cables neatly. Cross them over each other in looms
Get New sparkplugs (Do not overtighten. Turn to seat snugly, then 1/4 turn more
