Have you tried putting the chip back to stock to see if that is the problem? good luck.

Your limping the transmission. This is not a good thing. By keeping the truck under 2000 rpms, its the computers way of protecting the truck from doing more damage to the transmission. What setting do you have the super chips on? Read up more on it at dieselplace.com. Basically you are shortening the life of your transmission. I believe its the clutch disks that are slipping.

Will is right. Sounds like a limp, and the more you do it the easier it is to reproduce. You're wearing out the Alli with your chip. I have 100K on my HD and I finally had Suncoast fix my problems after eating up the original Alli with my mods.

Arn't your panties in a knot. :cheers: I was simply agreeing on what you and Ryan stated. The programmer needs to be removed to rule out this as the problem.

Maybe you should have selected a different emoticon if you were agreeing, calling someone stupid is not a good way to win friends.

It's your fuel filter. It happens to my 2005 D-max every 8-10k miles. Now I have it changed at every 8k miles to avoid it. We have almost 100 D-max trucks in our company and this is the most common problem.

 

Good luck

these allisons have more failsafe programing than you can imagine ,you can tear a cooler line of and it will live,I think to its a code and it is defaulting to get your attention and it worked ,I think chips are a waste of money,the cost of alli and d-max parts would scare you stupid,god help you keep your money in your jeans ,these things are fast enough stock,have you tried an 07 yet?good luck to you friend.

You could have a fuel pressure issue. Besides replacing the fuel filter a quick check is pull the oil dipstick to see if it's over filled and smells like diesel fuel. If it does get your injectors replaced they should still be under the special policy warranty this is assuming you have a 1 motor.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
