less than a year ago, i purchased set of 72lbs (750cc) injectors from marren fuel injectors. they were installed in my car, and everything was fine.



this past september, while tuning the car, we noticed that the front plugs were lighter in color than the rear plugs, suggesting that there was a difference with the injector flow. immediately, i sent the injectors back to marren to be cleaned, and sure enough the front primary injectors were flowing unevenly, the front rotor was 3% less than the rear. i received the injectors back with both injectors cleaned and flowing perfectly according to the flow sheets.



since i recieved the injectors back from marren, i have had difficutlies sealing the injectors, and Tim from that company suggested that i send them the rail and the injectors so they can fit them with the correct o ring.



i then sent them the rail and injectors, and they said that they fitted larger o rings and everything was sealing properly. and all they have to do is give me a "free" flow testing just to make sure that everything is still perfect.



i recieved a call today, they said that the injectors did not have the proper spray pattern, and flow rates are at least 5% off from normal, and the injectors need to be replaced otherwise risking the engine's life.



between the 3 week span that i recieved the injectors and sent it back to them, these injectors DID NOT even have fuel flow through. i was so concerned about the top O ring sealing that the injector clips were not installed, so no current even touched the injectors. after telling them that, Russ (another person from marren) suggested that i have very currosive agents in my gas? HOW COULD THIS BE, it is the same gas that was in the tank before they cleaned it in the first place. to add to that, i have 2 new fuel filters for each of my rails. they then went on that i could have had aluminum oxide in my fuel rail that curroded the internals of the injectors.



they claim that there are no physical damages to the injectors. and went on to say that i should send the other injectors that i got cleaned to them to be tested as well.



now, of course i cannot trust these injectors whether they were lying to make me buy new ones or not. but i sure smell something very fishy going on.









should i ask for my stuff back, and call the Better Business Bureau?

troubleshooting further with the same company may bring up the cost ...

and may not even clear this problem at the end of the day....

unless of course they are footin the bill to resolve the issue..

perhaps itd help ease your mind and possibly be cost effective if ya just get new injectors ....

yeah i already got new injectors today, and not from marren.



its just a shame that i spent 150 dollars on these injectors to be used for several thousand miles, another 50 to get them cleaned, and for them to crap out for no aparent reason.

update... they told me the pintel was worn out, and causing the irregular spray pattern.



only problem is no fuel or anything went through the injectors. and the injectors are the delphi disc type injector where the pintel is not exposed.



a member of the forum, 2turbos, is helping me determine if these are really bad.



he pointed out that injector lifespan sometimes go to half a million miles so its highly unlikely that they are wrorn out

That sucks, Marren seemed like a reliable source for injectors.

that sucks.

are there any local companies that will clean/flow test injectors?
