Had the Fuel Injectors Cleaned

[Burbman]

Was using Mr Injector out in Idaho, found a place here on LI (actually 2, but one really close by) that use the same ASNU ultrasonic cleaning technology. These are from a 2002 GTP, stock. Look at the flow before and after, they were only flowing at about 2/3 of what they are supposed to.

can you notice a difference in how the car runs ?

[Burbman]

Not yet....picking them up tomorrow, just got the report via email this evening. Fuel rail was out since SC bearings went bad. New reman SC from PSE in OK, ported and going in too. Will post back when it's together

Holy crap $22 per injector? Need to get my injector test stand back in operation.

That also includes new filters, pintles and O-rings

I use an ASNU where I work. I'm surprised to see all six injectors dirty nearly the same like that. I also would think that if there were only following ~60%, they would have tripped the Check Engine light. That's a lot of fuel to make up with LTFT adjustments.

I'm also surprised to see they all cleaned up to within 2cc of each other.

I agree. I had the injectors ASNU cleaned on the 98 and the 01 and they cleaned up similarly, I will have to go back and see what the "before" numbers were.

Agree with you, I actually checked to be sure he had the right part# and specs, and it's correct. Does seem fishy for them to be so clogged. I'll see if I can get more info when I go pick them up today.

I use a different machine, it's a Star brand and is pretty old, but does everything that you need for cleaning fuel injectors. I can backflush, ultrasonically clean (separate unit) check balance and do leakdown tests. You would be suprised how much injectors can clog up. I never really saw it as bad on disc type injectors, usually the screens were dirty and a backflush would make a hell of a difference, though not as much as you posted. Most of the issues I had were with pintle style injectors. Fuel injector cleaners are bunk and don't do anything. I just need to check the machine out again and get the platter fixed so it'll do balance testing again.

Cool! So I wound up at $120 cash, so $20 each, not bad

Curious to know how much different the car runs, including any mpg difference. 👍

Just noticed today that the DIC os showing 19, never got above 18before.

The car runs a whole lot better than before...but that's also a reman and ported SC, a squeaky clean LIM with new gasket, new vacuum lines and the cleaned injectors, so hard to say how much is due to injectors alone. Wasn't like i was cleaning them to fix a problem, just because they were out anyway..

What do you guys get for mileage on a GTP?

I was a 90% city driver when I owned my car, it got 14-16 city in the summer and maybe saw 18ish if I drove normal. Freeway was always 30-32 going up to the cabin doing 65-70mph.

My daughters 2007 gets about 20-21 mainly city driving. Don't think she is into the boost much. My other daughters 2003. I drove for about 3 weeks for work. Highway miles. Not into boost much. And got about 24 ish. I had the DIC up to 25 for a while with 1200 miles on the reset but never hand calculated that high.
