8pcs Fuel Injectors 4Holes for Cadillac Escalade chevy Chevrolet Silverado GMC Sierra Hummer Buick Isuzu 4.8L 5.3L 6.0L 17113698

2000 Yukon XL 5.3They cleared a p0300 code & are working well. They seem to be a great value so far.....xxx***xxx Update......I put these in a 2000 Yukon XL 15000 5.3 last year in a work truck I was building....at first they seemed to work fine. The truck was to be used as a back up truck so it sat until November when my other truck started to become fatigued. As soon as I tried to go get an emissions test...all sorts of codes started to pop up preventing me from passing the test so I was forced to drive my other truck because didn't have to figure what was going on with the "back up" truck. Well finally caught a break & started chasing codes & fuel trims that were all over the place. The final result was that these injectors leaked as well as pumped too much gas which resulted in running rich codes....p0172/75.....code p0300 .....code p0420.....also put so much strain on the system that they started causing coil packs....I bought on here.....to short out one by one. Flushed out the old injectors & put the back & the truck has been running fine for a few months now.

I bought these cause it stated they were a fit for my truck and even thou they are 4 port feeds there wouldnt be any problem or a need to remap the pcm. After having new heads installed l installed the new injectors cause the fuel cell had rusted clean thru the metal top and my fuel tank was full of dirt as was the rail and old injectors. When i started my truck it started flashing check engine light. After reading the codes l inspected the new O2 sensors, new plugs and wires,and so on not thinking or know to check the injectors. Well long story short, injectors were dumping so much gas in cylinders that it washed out the rings and l starrted getting oil in the intake manifold. Upon changing the oil l found it to be half oil half gas and aluminum shavings. So l hired another mechanic who told me to toss the injectors and get the 2 port injectors like the original. Then sqirt a a half of shot in each cylinder of transmission fluid before start. That helped but the newest injectors l got from here had 4 that leaked gas thus messing up the motor even more. Beware if your a moon light mechanic like me buying cheap online isnt always wize.

I replaced all 8 injectors due to one faulty injector and higher mileage. I am now getting Bank 1&2 fuel trim system Rich codes (P0172/P0175) Fuel trims are maxed out on both banks meaning the new injectors are dumping way too much fuel. Need to contact vendor and get my money back or get the correct set of injectors.

Thought I'd replace all of my injectors instead of the one that went bad. That was a very expensive mistake. Not thinking that I would receive inoperative injectors, I started chasing down continual misfires. Needless to say I spent a lot of money, time and effort replacing plugs, wires, coil packs, and still had multiple misfires. Intake gasket leak? yup changed that too, but still didn't solve the problem. Had I just purchased AC Delco which is OEM for my Chevy, I would have avoided hundreds in lost money and time because of I thought a cheaper product would actually work. WRONG!! Do yourself a huge favor, don't buy cheap products, buy the best, you'll never regret it.

Working great so far. Packaged REALLY well, very clean, fit really well, look nice, quality looks & feels identical to the Delphi's that I took out. Comes with 3 year warranty! I went from 2 hole to these four hole injectors. Truck is running strong. Excellent seller. 2001 Chevy HD 6.0 (LQ4).

this is a cheap no good replacement do not buy

After verifying a correct fit before ordering I paid to have them installed. They threw an error code as they were not correct as indicated by previous reviews. I had to have them taken back out and have OEM injectors installed and it fixed the problem. Don’t do it. Lots of wasted labor and time.

I would not recommend this to anyone pore product
