    LB7: Injectors or Something Else?

    Thanks for all the input, guys. I decided to park the truck and buy a cheap car for now. Once I'm done with school and have more time/money I'll go ahead and replace all 8 of them. I appreciate your help! :thumb:

    LB7: Injectors or Something Else?

    Would I be crazy to try replacing just #1 right now and hope that buys me some time? I'll graduate in May, so after that I'll have more $$$ to work with. I was reading the fermenator thread as well, that's why I asked about tuning.

    LB7: Injectors or Something Else?

    Yeah I'm leaning towards buying a cheap car and parking the truck until I'm working full time and can afford to do it the right way. Is it necessary to replace the high pressure lines too, or can I just clean the old ones?

    LB7: Injectors or Something Else?

    OK guys, I've finally accepted the fact that I'm gonna need new injectors. :banghead: The shop says #1 is hung wide open and 7/8 are out of spec. Now the question is: should I drop in some stock VCO nozzles and just plan on doing them again in the near future, or bite the bullet and go with SAC...

    I swapped it with a good battery from my dad's truck just to be sure and nothing changed.

    LB7: Injectors or Something Else?

    Guys, I'm at a loss. I checked the 2 main harness connectors going to the fuse box, connectors at the FICM, and injector harness connectors and didn't spot any problems. Also checked for chafing around the alternator and everything looked fine. Found out one of my batteries is bad but don't...

    Thanks, I'll go through the wiring again when I get a chance. The codes didn't show up last time when I checked.

    OK, I cleaned the injectors tonight using this method: Injector Cleaning The truck ran for an hour and a half. There seems to be less smoke now, and I got some more information: 1. The SES light came on this time and gave me 5 codes (attached). I haven't had a chance to look them up yet...

    I can't see any wobble in the balancer. The engine cranked for 4-5 seconds before starting up this morning. I'm going to try to get ahold of some injector cleaner and run that through today.

    Filled up about a week earlier and also changed the filter around the same time. I'll start it up tomorrow and look for some of the things you all mentioned. Sent from my XT1254 using Tapatalk

    I'll check that. Seems pretty unlikely with a stock (as far as I know) tune though... Sent from my XT1254 using Tapatalk

    That was cold. I was scared to run it for more than a few minutes. Sent from my XT1254 using Tapatalk

    No codes and no blow by. I haven't been able to read the rail pressure with my scanner, but will definitely have that checked before I tear into it. What should I be looking for with the balancer? Sent from my XT1254 using Tapatalk

    It's an app called Torque and a cheap Bluetooth scanner from eBay. I checked the oil and it seems fine. Sent from my XT1254 using Tapatalk

    Should I worry about doing more damage by running it like this? It knocks and shakes like crazy.

    LB7: Injectors or Something Else?

    Yeah, I'm looking at beaters on Craigslist right now. Any chance I could run some cleaner through them and prolong it a few months? I'll graduate in May, so I'm just trying to get by until then.

    LB7: Injectors or Something Else?

    I've only had the truck for a year so I don't know a lot about its history. I do know all 8 injectors were replaced under warranty in 2008 at 102,000 miles, and I'm assuming that is the set that's in the truck now. The current mileage is 210,000. The problem is I'm in school right now and...

    LB7: Injectors or Something Else?

    My truck has been running great with no haze at all. Halfway through a 10 mile drive, I noticed a bad lope/knock at idle. Now it's blowing white smoke at idle and a lot of black and white smoke under throttle. I checked the balance rates while in gear and they look terrible (see attached)...

    Yeah. I didn't give it time to warm up though because I'm scared of causing more problems by running it like this.
