My Lightning is acting goofy now. The factory speed limiter is 'supposed' to be 100 mph. It used to go that fast. However, last night on the way home from work I decided to 'clean it out' and run it up against the limiter. Well, it acts like the limiter has been reset, 20 mph slower! It got to 80 mph, then shut off, sped back to 80, then shut off, etc. It hasn't been anywhere for anyone to do anything to the computer. It still drives like normal, it just shuts off early. What could be causing it?

Since it's getting ready to roll over 200k miles, we thought it would be cool to stick it on the chassis dyno. Since KK had her's done, we thought it would be cool to compare her 95k mile truck to my 200k mile truck. But that would be pretty useless with my truck acting the way it is now.

PS, KK's ran up to 120 on the dyno and never shut off. But I'll lewt her tell you about it if she wants to.

coil packs? (can't be that! you ain't got them.)

fuel starved?

Is there a failsafe mode that it could be in to you home when stuff get's scrambled?

I suppose I could switch tanks and try it again, that would eliminate a pump problem. But it runs right up to redline in the lower gears without any problems. But in Drive, it gets to 80 and shuts off, just like the speed limiter has been set lower. I even tried it once in OD, and it still shut off at 80 mph.

There's the universal answer to all computer woes... (when I don't know what I'm doing). Disconnect the battery, turn on the headlights, reconnect, fire that muther up, and take her fer a ride. Real hard to diagnose without being able to read the tables. Maybe a disconnect will reset it. It's a freebee.

Cheater!! Codes should be cleared properly, at the dealership!!

Psssst, Rob, when you do what Blue suggested, and you disconnect the battery, don't forget to let it sit for at least 30 min to an hour with the headlights on. That method works really well!

After having Bluemule mention fuel starving, and having one guy on NLOC suggest cleaning the fuel filter, I decided to try switching tanks. It ran up to 95 before I decided that it was fine (and before a lawman decided to give me a fine. )

Now to just replace that stupid clutch fan.

Just a little bit. It has a 'slight' vibration when I get into the throttle hard.

I would worry more about catastrophic failure of the clutch.

I didn't get pulled, I slowed down before that occured. I figured going 95 in a 65 was a good way to get attention though.

Fuel pumps and filters....my 86 had similar symptoms, dang thing has 3 pumps, one in each tank and one on the frame. Also the filter on the frame didn't change anything, but the dual tank control had another filter, it was between the tanks, it was completely clogged. Ran like it should after all that.

Them NC boys don't play either! We had one threaten to haul him off to jail back in '91 or so for doing 76 in a 55 on I85. Wasn't like there weren't 400 others doing it.

Nowadays you have to be doing triple digits to get pulled over in NC. The cops here are the most slack-a$$ group of 'law enforcement' I have ever seen. Another board I am that is NC based, a couple of officers on there even admitt they wont pull anyone over unless they are doing +20 over the posted speed limit. That's stupid! Why post a speed limit then? I say all the time there is no speed limit here, just some posted suggestions.

And if you do get pulled over, you hire a lawyer and they will get the whole thing dropped.

Speeding in Atlanta is horrible, I-20 in downtown is posted at 50mph, if you go less than 75 you'll get run over. Away from town is worse, 80mph is the norm.
