In the center of each valvecover is a well with a wire in it each wire has a seal cap attached pull up and youll find a stem which goes down a tube this is part of the spark plug wire the plugs are at the bottom of this tube youll need a long adapter on your wrench and socket for this job and you can extract the plug using the wires stem

Well, if it isnt broke, well you know the rest. As a kid in the shop we were directed to add dextron 3 to the fuel to decarbonize an engine. I have practiced this and my ford 5.8 that just hit 280,000 .. Cant say that was it, but point being it didnt hurt it. They actually make a old school fuel additive called Marvel Mystery Oil, It is Dextron 3 mostly. The oil consumption test you can do, Do a oil change , after 1000 mi. drain it and see that you have what you put in. That is what they are charging you too do. Is it worth it? umm, no

SOURCE: 2001 Isuzu Rodeo 4WD. CHeck Engine light on and

After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.

SOURCE: diagnostic code for isuzu rodeo p1125,p1295, and

P1125 is: Throttle Positioning Sensor intermittent.
P1295 is: Multiple faults on bank 1 (right)
P1550 is: Power steering pressure sensor out of self test range.
Well the ECM recognizes 3 codes. Were these codes stored as inactive (in the history section)? Or are these codes all active? Code P1125 and P1295 may be related but P1550 is separate. How else may I help?

HOW DO YOU KNOW YOUR SPARK PLUGS ARE OUT


You mean when do you know your spark plugs are not working? Your engine will run rough and your check engine light will be lit. You'll have codes of P0301 through P0306 depending on what cylinder it is.

Cose p0306


Code p0306 means that cylinder six is misfiring. Take it to a mechanic or try to fix it yourself. Change spark plug, plug wires, solenoid.

96 dodge caravan 3.0 has p300 and p306 codes,


A P0306 code means that the the ECM has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

A code P0306 may mean that one or more of the following has happened:

Faulty spark plug or wire, Faulty coil (pack), Faulty fuel injector, Burned exhaust Valve, Poor compression, and Defective computer. 

Check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the Caravan, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). The number six cylinder is the one towards the radiator and drivers side. If you are going to change all the plugs and wire keep me posted, be glad to help. Good luck and hope this helps, P0300 just means multi miss fire.

Its your No. 6 Injector. I had the same problem on my 97 Jimmy. Replaced the SPYDER injectors and it runs fine now.
