Forgot to add something. Tapping the accelerator will turn off the CEL, wait a couple moments and it will come back on at idle. Anyone? I'd really like to get this thing running right by Saturday night at the latest. Right now it's sitting outside just idling; seeing if that does anything.

Is there anyway that the 34 and 94 codes are related? Will changing the stepper motor in turn fix the misfire? Seems to be a possibility since the stepper motor controls (at least to a degree?) timing? Maybe my logic here is flawed; still learning..... So should I let the truck idle for a...

I did replace it myself...only one way to learn right? The system was bled but probably not the right way, seems to run fine though other than the above problem codes and related problems. I set base(?) timing according to the mark on the flange of the IP and mark on the timing cover. Don't...

Faaaaar east side of Raleigh, next to Rolesville...North Carolina, of course.

BTW both of these are after replacing the IP.

There was a whole 'nother post here but I did a little more homework and fixed a couple problems. Anyway here are the two that I'm getting. I know the 34 is the stepper motor but what is 94? Is the only solution to 34 replacing the stepper motor?

Maybe a little too late?: 305/70 shorter but the same width...roughly a 34x12.5. Needed a slight torsion tweak to clear certain parts.

Finally remembered to pull codes this morning before work. Here's what I got: 42, 65 and 67.

There can be a rather large amount of vacuum in the tank and from the threads I've been reading on here from searching vacuum = a problem. I did read that some guys got a new cap but accidentally got one for gas instead of diesel which apparently caused some sort of problem. So I made sure to...

Ah, I will have to try that tomorrow getting a little late tonight. Found the problem I think. There was a slight solder bridge that was extremely hard to see. My brother found it with a multimeter. We got the speedo right though. I'll reset codes before I go to work tomorrow if I remember to do...

Every time I pull codes I only get 12 (or the occasional 78). Whenever I have had to pull codes (including now) I have never gotten one for any brake/ABS problem. This is not like a Ford in that it does not have a separate diagnostics link for ABS, correct?

Didn't know where to put this one so I stuck it here. Just got done with my DIP switch mod in my Suburban yesterday. I'm pretty sure I got it right but the ABS light still pops is this right? I figured with the right calibration the ABS would go out (oversized tires). Maybe I'm off? I haven't...

Well did the RPM hold test (took the long way home to make sure it was nice and warm). Once I figured out how to keep my foot still long enough to keep it at a certain RPM it held rather steady at 2150. No RPM dropping/spiking during the slow revving. I thought it was the PMD when it started...

NVM - Been relocated. Not to the bumper yet, the extension isn't long enough for that. Right now it's on the left side battery tray; it's off the motor so no more vibration but not sure about cooler air. HighSierra - ??? Haven't read about that one yet. If I have any time at work tomorrow I'll...

I think mine may be dieing but I'm not sure. Problem: Doesn't take much to set if off. I'll drive home from work (est. 20-35 minutes depending on traffic and route), let it idle for a couple minutes to cool down and shut it off. Eat some dinner and maybe leave for short drive, elapsed time from...

Good to know. I need to do this on my Suburban.

Nice 'Burb. I bet if you dropped the GFX kit the 36s would fit better. I'm fitting 34" tires with only a 1.5" TT. I always did like factory centercaps on aftermarket wheels. Nice.

I didn't see an edit button so I'll just post them. In the second pic it might look like the exhaust and shock are touching but there's decent room.

Well that wasn't supposed to happen, I'll fix that in a little bit.

ASK! and ye shall receive. Front looking back Back looking front........and up. I like my Diamond Eye system. It does have a nice grumble to it and can get loud when you give it more stupid. Especially sounds sweet under full throttle. My only complaint with it is it sounds too...
