Now if you can figure out which PN they were and maybe you could buy one from them, or have those serviced.

cool thanks, we gotta pull em anyway, so we can tonight and see if we can find anything on them, but i didnt see anything on the 3 we pulled

[banzai92gt]

ive come to the conclusion.. i hate injectors..

lol

Just think, I had to do this on a GMC Jimmy TWICE but if you know anything about those the injector housing/spider assy is INSIDE the upper intake. That wasn't fun. It's about 2 1/2 hours or so of work before I could even "test" the injector in another spot.

yup they are not fun to work on injector wise for the jimmy's lol.

[banzai92gt]

still not sure which injectors are CURRENTLY other then what brand they are..

waiting on chris to check his ebay history.

You could also just bring them to a shop that does injector cleaning and have them test/fix and flow them to see what they are... Might even repair the one you have issues with. It could just be clogged. I know that's wishing for a bit but hey it's possible.

[outtamymind]

i don't know of anyone around calgary that does that sorta thing

[banzai92gt]

im taking them on friday to get em cleaned and flow tested, gonna cost me $150 though...

That sounds about right... Hopefully they can identify/fix the issue with that one. Make sure to package it up special so he can test it first. The place I used did not charge me to "clean" one injector that I had go bad on my wife's impreza. They only charged me for the ones that were good.

one of my buddies said he would do a full clean, test, drip down, replacement of all soft parts for 15.00/ea plug.. but i have to wait 12 days until he gets back in town...

36 pound injectors for a GP GTP should be plenty, even at 43.5 psi.

The newer pencil injectors from GM are good but other than that I would stick to FMS (ford) injectors as I have tested hundreds of injectors and they have always been the most reliable.

Stay away from GM fat body injectors or any fat body (smooth body) bosch injectors.

HAd the injectors flow tested and cleaned.

one injector wasnt firing at all.... buddy cleaned them all, tested and got em all working.

they are 42lbs and flowing great now, problem is there is a 6% static flow difference between the injectors. so i am gonna try and find a new set and have em flow tested and get em closer to the 3% ideal rate.

Reinstalled the injectors and plugged in the DHP, almost no misfires.. so now its time to TUNE!!!

Check with some other flow shops... they may be able to correct the 6% flow difference where just the cleaning process wouldn't.

[banzai92gt]

he is the best in surrounding areas, he replaced all soft parts on the them as well as flow testing before and after cleaning.

Deautshwerks are actually just bosch injectors that they take, scratch off the serial number, change a bit and sell as there own...
