    Twins with Twins, Anyone?

    Aww yeah, that's what I'm talking about.

    LB7: check engine light

    You're going to need to get the codes read. These trucks are advanced enough there's no point guessing what might have it unhappy. Most auto parts stores will read codes for free. Post back what code(s) are set, and we can help you out.

    Confused about fluid coupling issue

    That last screenshot shows 2385 engine RPM with 1084 slip, so the input shaft wants to be at 1,301 RPM. That's probably half your problem right there. The trans tuning is setup so that while merging up an on-ramp it is trying to pull the motor down to a really low RPM. Imagine if you had a...

    LMM sluggish/smokey once hot at 2000rpm

    The first few replies were talking about having the tuner diagnose the issue. I guess not saying it was a tune issue, but I'm not sure sending logs to the tuner is the right way to diagnose this. But I also agree with you that we can't condem the injectors with what we know so far. Though if I...

    LMM sluggish/smokey once hot at 2000rpm

    The fact it does this on the stock tune, with only 30% injectors, tells me it isn't the tune. I wouldn't waste your tuner's time with logs since it did it on the stock file too. Worth checking for leaky injectors as mentioned, can even do a compression check. I suspect it is bad injectors, but...

    Fuel Line Question

    I'm on a 12mm CP3 and 75% SAC injectors with a S371 and have no issues with the stock supply lines, at least along the frame. Once they hit the motor it goes straight into the CP3, but that is because the factory routing was stupid and annoying. I bet you can push 700+ HP through the complete...

    The new Limo

    This is why I daily drive a 1998 Pontiac Grand Prix. I'm always paranoid someone is going to wreck into my truck or Suburban. Sad that the vehicles I like the most, I drive the least. But like you say, this is why we can't have nice things :(

    Lb7 long cranking to start

    X2, get a scan tool on there and do some basic diagnostics. The FPR can theoretically cause a hard/no start condition, but that is not normal. In fact, I have never heard of that happening. If it can't build pressure to start, there are only a few causes: bad CP3, bad injectors, air in fuel, or...

    Seriously?

    What's it even supposed to do? Doesn't look connected to the airbox, so not a "ram air". LOL wow.

    Twins with Twins, Anyone?

    Is there a tube to balance the reservoirs at all? Is that handled through the return system? I'd imagine you don't want one reservoir slowly overfilling while the other depletes.

    Looking good! Hopefully the pump cooperates with your feed setup.

    Oil cooling

    I'm in for one. I don't have anything against the new filter, but I have a ton of PF2232 filters laying around, and all my other rigs still use that filter.

    Twins with Twins, Anyone?

    That was a rare engine in that car. I've never seen one in a junkyard. Only seen one in the wild even.

    Hardwire Dashcam from Mirror Power

    I usually get a sunroof harness from a junkyard Suburban which gives Retained Accessory Power right to the center console. Then just wire in a cheap 12V to USB adapter. Works great. Pulling power off the mirror means the dash cam would shut off with the key, which might be fine for most use...

    LML Sta Bil Diesel Fuel stabilizer for long term storage

    I don't understand how sitting on concrete would be any worse for a battery than sitting on the metal battery tray in the vehicle. For winter storage, we are usually too lazy to take the batteries out of the equipment. Just stick a trickle charger on it, and if we are particularly motivated...

    2002 Lincoln mountaineer missfire and low power

    Did you ever get new injectors? If not, the lean reading on one bank could be legitimate. New sensors won't hurt, but with questionable injectors, it may still be lean/weak.

    03 LB7 security light

    Something like AllDataDIY or a professional subscription like Mitchel OnDemand would have them. I started a thread asking about increased quota, so hopefully they bump mine up and I can post those documents. Disconnecting the batteries for a few minutes is how you do a hard reset on all the...

    Attachment Quota

    I'm trying to attach a couple PDFs of schematics to help a member diagnose an issue (thread, post), but I seem to be 8.3MB over my quota somehow. I guess the quota was reduced at some point? The attachments are pretty small (<300 KB total), and would be useful information to keep around. I hate...
