Please help!

my Dodge RAM B250 1989 started to lose power, began idling inconsistantly and then stall. I checked the throttle body and realized that the left injector was not working, only the right one was spraying gas.
I am in bolivia with my car now, so I guess the reason could be bad gas quality, (84 octane) is that possible? Please, could somebody advise me how to clean the injector, and how to depressurize the fuel system? Or whatever else I could do? I dont really trust the local mechanics...

Thanks

The injectors have little fine mesh screens that can be cleaned once removed
The injectors fail, cleaning might do no good. Is it still ticking rhythmically?

Also try switching them side to side and see if the problem stays with the wiring or the injectors. It is very simple to remove and replace the injectors, if you have a torx/Star Bit.

Don't know how parts acquisition in in Bolivia but rock Auto Ships internationally.

You can depressurize the system many ways. I just remove a line on the fuel filter, along the frame rail passenger side, under the side doors.

 

Thanks for answer! I added some injector cleaning fluid into gas tank, and now both injectors are working. Still there is something wrong, the engine runs irregularly and has less power when cold. This gets better when warm, but irregular idling persists. It seems to me, that ihe idle speed (or the quality of gas mixture) gets so low that the engine nearly dies, but some regulator does something to avoid this, so it wont die...and this repeats. When I put gas when warm, its is ok, when i put gas when cold, it runs irreularly even under gas. I ll try to clean the injectors, and also...i am at 4000 m above sea level, and the gas they sell here is not top quality. So this could worsen the problem also?

 

Yes, the injectors are ticking rytmically....

 

that usually means the PCM is on the way out.

 

Do not need to clean the injectors. Injector cleaner worked.

The throttle linkage to the Throttle Body should have a "limiter set-screw" If you adjust the set-screw a little, the warm up idle will be better. Or maybe the kick-down for warm idle needs to be checked. Maybe clean the outside linkages and lubricate the linkages that connect to the Throttle Body on the van.

My van is the new generation, your van is a mix between carburetor and rail injectors called Throttle Body Injection.

 

cleaning the injector might not have done it--replace it
