Hey group, the other night I got the check engine light come on. I was close to an Autozone so I stopped and had them read the codes. Came back as "dirty fuel injector/injectors". Put some Lucas injector cleaner in the tank and went on my way. Light went out a while later that night. That was 2 days ago and then today it came back on again, ran codes at home and came back with "bank 1 running lean". So I am thinking that the injectors need a good cleaning. Truck is running great and getting 14 to 15.5 mpg according to the DIC. Put a can of Seafoam in the tank this afternoon but I know that is just a band-aid. What is a good way to clean the injectors without a complete tear down of the fuel system It is a 2007 Yukon Denali with 213,000 on the clock on a 6.2. Thanks.
Will have to look that up on line. I remember a long time ago I remember that you could run cleaner through the fuel rails. Seems like that would work the best.
Is it OK to use these products on the new generations 21-23? I have 30k miles and want to try one. The manual recommends the AC Delco version, but I assume the ones you mentioned should also do the trick?Did this about 18mos ago... Seemed to work great. 9v with alligator clip jumpers causes an audible "click" as the injector opens and spraying cleaner through showed 4 distinct nozzle fan type spray patterns. Two of mine were not playing nice on first spray but straightened right up on second. CHanged o-rings same time also...
from my experiences:
Techron= A
B-12= A
Seafoam tank and whole can through vacuum hose at 2000rpm= A
Royal Purp= A+
Cataclean= A+
edit: used brake cleaner to spray out my injectors...
Yes, as long as it's a gasser and not a diesel. Chevron/Techron would be my choice.Is it OK to use these products on the new generations 21-23? I have 30k miles and want to try one. The manual recommends the AC Delco version, but I assume the ones you mentioned should also do the trick?
Thats direct injection.. Techron will always help the entire fuel system.Is it OK to use these products on the new generations 21-23? I have 30k miles and want to try one. The manual recommends the AC Delco version, but I assume the ones you mentioned should also do the trick?
Berryman's B-12 is my favorite of all time. Have used it almost all my adult it seems. But you should never mix these different additives in a tank of gas. Run a tank with just gas between Seafoam and B-12 before you switch to B-12 or back to Seafoam. I have never used Seafoam for anything, not even a solvent cleaner for the carb or throttle body. Just do not care for it. My Dad was a Marvel Mystery Oil user and swore by it. I did use it because he did until I got married and then I ventured out to others till I began to use B-12. I used Hot Shot's Secret a couple of times last year and the results were inconclusive. May give it another try later this year but it is rather pricey for me. I have also tried the Hot Shot's Secret friction reducer but could not really tell any difference. I just don't put enough miles on my Frontier to have much faith in anything but B-12.+1 for the code(s). There are no monitors specifically to tell if the injectors are dirty. Yes, clogged fuel injectors could cause a lean condition. But, there might not be an actual failure with the injectors and the DTC could be a failing O2 sensor erroneously reporting Bank 1 being lean. A failing O2 sensor could also cause a lean (or rich) condition.
The DTC for the engine running rich or lean is determined by the O2 sensors. If the problem is isolated to one bank, a quick at-home test for the sensor is to swap it with the one on the other bank and seeing if the code changes to Bank 2 running lean. If your undercarriage is rusted, don't even try this unless you plan to replace the sensors. Other common causes for a lean condition (perceived or actual) are exhaust leak ahead of the sensor and intake manifold leak, although this one usually causes a rich condition.
As for additives, I'm a fan of Berryman B-12. It's about half the price of Seafoam and more potent. I run my tank to around 1/4 tank or less and add a can. I run it until really low then fill up. Unless running E85, I stick to Chevron/Texaco or Exxon. NEVER Shell. I use the B-12 every 3-4 refuelings.
