With the engine running, unplug 1 injector at a time. The engine should stumble a bit when u unplug it so youll know that injector is working. Go down the line 1 at a time. Besure to plug it back in before going to the next. When you unplug a injector and nothing happens, you probably found the dead one

SOURCE: shakes on take off

it could be an injector but not common, when you changed the trans fluid was it dark brown or smell burnt? there could be wear in your gearbox which would cause this, Check driveshaft universal joints for any play.

DTC P0211 on 2002 7.3 Diesel


The symptoms for this code will likely be a misfire and a rough running engine, poor acceleration and the MIL will also be illuminated....
The cause for this fault code could be any of these:
A bad injector.
Open in the wiring to the injector.
Short in the wiring to the injector.
Bad PCM.

This is how you fix these ^ problems:
First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
Check for voltage at the injector connector. It should have 10 volts or more.
Visualy check the injector for damage.
If you have access to an injector checker, activate the injector and see if it operates. If the injector operates, then you likely have an open in the wiring, or a blocked injector. If you don't have access to an injector tester, swap it with another injector and see if the code changes. If the code changes, then change the injector with a new one.
At the PCM, remove the driver wire from the PCM connector and ground the wire (make sure you have the correct wire. If your'e not sure, do not attemp.) The injector should activate.
Replace the injector.....

I hope this information gets it done and helps you out.......

P0203 only when the engine is hot


The causes of a P0203 engine light code could be any of the following:
* Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
* Open in the wiring to the injector
* Short in the wiring to the injector
* Bad PCM

Check and test this possible solutions:
  1. First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
  2. Check for voltage at the fuel injector connector. It should have 10 volts or more.
  3. Visually check the connector for damage or broken wires.
  4. Visually check the injector for damage.
  5. If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
  6. At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
  7. Replace the injector
Hope helps.

Running on 4 cylenders instead of 8. already replaced brain ,checked injecters for pulse and not all pulse


We check injectors with a needle stethoscope to locate the bad one. After we use injectors check lamp, (it is not costly and you can buy on line). If the light pulse, we replace the injector. If not then is an electrical problem. If you will replace the injectors please, buy original one from Cadillac Dealer, they are expensive. I bought aftermarket for north star engine, they were bad, and I bought again the original one. No more problems with injectors. Mine is a Cadillac Seville SLS. Hope will help.

Ford trouble codes on a e 250 with a 5.4 eng codes 175 and 205 what is the most likly cause


P0205 Injector Circuit Malfunction - Cylinder 5
P0175 System too Rich (Bank 2)
A code P0175 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled
  • There could be a vacuum leak.
  • There could be a fuel pressure or delivery problem
Possible Solutions Possible solutions include:
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect fuel lines for cracks, leaks, or pinches
  • Check the fuel pressure at the fuel rail
  • Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

Throttle body injectors not fiering but there is fuel pressure


the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up
