Where to send injectors out for service?


The Fred

Recommended Posts

Well my pay will be here soon so I'm going to send those blasted darned injectors:

Out for service.

The one I was sent to online he never responded to my message so are there others?

PS: If the injectors don't fix the car we're going to have a heyday destroying it all to heck :lol:

No more games it is the cars last chance :angry:

I was trying to solve what appeared to be an injector problem and sent my injectors to:

http://www.cruzinperformance.com/fuelinj.html

They turned out to be fine, flowing fine and within 2% of each other. I was told that I did not need to run the injectors through the rest of the process. I was charged $20 and the return shipping. An honest businessman that I can recommend.

Note that at this point in time he is dealing with a friends unexpected death, and is not taking in injectors for a while. If time is not a big issue, I would try to put off this service and send them to him when he is ready to resume his cleaning and testing service.

PS

It turned out that the problem that I had, was the Ignition Control Module failing; syptoms nearly identical to bad injectors ($330 for the replacement module from Rock Auto).

My cars smptoms were:

A rough engine condition at part throttle, occasional bucking at light load, and slight engine stutter when accelerating normally from a stop. I tested almost all of the electrical circuits and found them to be good; the engine acted like it is just not getting enough fuel to run correctly. Very similar to a carbureted engine with low float level, or partially clogged jets.

Did it throw any codes?

No codes were ever shown, except a low idle/nearly died condition, once or twice.

Very annoying to track down this problem.

Thanks for telling me about that,

If the injector repair doesn't fix the car..

I've already got the whole party planned out.

I don't attend parties,

But this one will/might be alot of a time.

I figure I will invite ten or so guys with their own firearms

Charge $25 each and provide steaks and roast beef

When it gets about dark we'll open up on the car like madmen

If the injectors fix the car,

Will yall be disappointed at not seeing the video? :lol:

People who get frustrated with their cars and do things like that really make me mad. Just because you cant, wont fix the problem doesnt mean some other caddy fan out there wont be willing to put money into it. Howabout you just sell the car for 250$ and call it a day. No wasted money on steaks and ammo.

I'll throw in 50 rds of FMJ's (Block Busters...LOL). Being the car is apparently possesssed, I still stand by my original thought that an exorcism might be in order.

Would it hurt to soak the injectors in say gasoline (or Kerosene) to loosen/remove the crud on them? Then maybe give them a shot of air? Just a thought.

Epriced, Besides GM stating that there is only one official method of cleaning the injectors (force feeding it upper engine cleaner and running the engine on it), I have been told that it was wrong to physically clean the injectors on the Pontiac 3100 that I did the upper intake manifold gaskets on. Check my posts #27 and #29 for my experience with cleaning the injectors. After cleaning them with upper engine cleaner and a nylon detail brush :blink: I ended up with mis-fires (P0300), until I replaced them. They were really carboned up and black, I figured whats the worst that could happen soaking them and just cleaning them up? Well the WORST ended up being, throw them in the trash! However, I still think that if I had a tiny pin to shove through the two tiny tiny holes in them that I could have salvaged them, who knows... Big job to replace them also..half the dern car had to come apart a SECOND time. See this thread for info on injectors:

When you're older you'll be mad with cars and pedophiles

That sounds good to me. I'll even go $300.

Too low :(

Here's an idea. How about using an ultrasonic jewelery cleaner with upper engine cleaner (or kerosene?) as the bath (cleaner)? You could hang them in there where only the tips (nozzles) are in the cleaner. Then blow with compressed air. There would be no physical contact this way. To me, it would be worth a shot, nothing to lose really. Those ultrasonic cleaners are cheap! If that doesn't work, replace them with used ones from a scrap yard.

A thin 'dress makers' straight needle may come in handy as well.

Kim, that's a good thought. Keep in mind that the upper engine cleaner is flammable. Worth a shot. I'm going to look into the ultrasonic cleaner, thx

For those interested, take a look at the link below that explains how this person services the injectors. Please note that at this time he is temporarily not excepting orders due to a friends death.

While this may not help anyone at the moment in time, look for others who do a similar service, and compare their methods.
