Engine Rattle

[Sevenznuf]

" lifetime powertrain warranty"?
Please, indulge me. Where do I get one?

I also got a lifetime powertrain warranty, engine, transfer case, and rearends, but they did make to tell me that turbos are NOT included in that warranty!

Easy guys! A little background regarding my experience with 91-93 octane. My truck is bone stock. I'm in sales and drive it about 500 miles a week, mostly on the highway. I noticed during around town driving that under light load from 2000 to 3000 rpm that it would ping a little running 87 octane. So, I ran 91-93 for a while thinking thay since it's a charged engine, it might need it. It didn't help the pinging but it did seem to make the "rattle" worse so I went back to 87 and the rattlexseems better. Who knows if what I heard was detonation pinging? These damn engines have more intermittent clicking and rattling than I've ever heard unless you wringing it's neck. Then it sounds pretty good. Noisiest engine I've had in any car I've ever owned. A real shame sincevit's such a nice vehicle. Between the engine noise, the low speed shudder, the highway vibration that I can't gey a solution to and stupid programming of the transmission so that the 10 speed skips 2nd, 4th and sometimes 6th, I'm seriously planning to trade it early next year. If the programming didn't run the rpm up so high in first so that the engine doesn't lug down when it skips the next gear, it be so much more pleasant to drive.

Skip shifting has been a thing forever. Now that there is a display that shows what gear you are in its an issue. This is the reason most gauges are dummy guages because people would complain about them moving.

If you have all the NVH issues call up Ford and tell them to help you. Blow up social media, leave bad google reviews, just be a pain in the ass and it will get fixed. By the way its a 4 cylinder, the Colorado will be 4 cylinder only next year. Noises and quirks for these are normal. Yours seems abnormal so it should be fixed.

Thanks for the reply. I'll be in touch. Would like to discuss a custom shift schedule that eliminates the skip ship, holds the gears like the tow haul mode without the hang up, but will up short shift sooner, like around 2200-2500 rpm under normal throttle. Would also want the engine tune to be as potent as safe with 87 octane fuel and eliminate the flat spot between 3500 and 5000 rpm on less than full throttle. I know. I'm asking a lot. Is all this something you guys can do with your tuner?

Is your tuner a piggyback that won't affect the factory warranty?

No problem we are always happy to help! We do offer custom shift schedules to eliminate skip shifting and we've also done some revisions with the tow mode up-shift schedule in normal drive mode without the annoying rev hang on deceleration. We do also offer 87 octane tuning as well but premium fuel will always net the best results. I've not personally sent a tune with shorter part throttle shifting, but I'm sure we could discuss the details a bit further in depth with the head calibrators and could have you record some datalogs to dial the shifts in further if needed as well.

You can return to stock with our device, however the days of being able to return a vehicle to stock and no one be the wiser are probably gone for good. As computers increase in capability, so do the memories of those computers. I would say the best advice is to be open, and honest with your dealership. I am not saying Ford will for sure honor anything, but just go into it knowing these are the risks but this is where our unparalleled experience is paramount. Feel free to give us a call, PM, or email and we would be happy to discuss our offerings a bit further in depth or to place an order as well. 313-561-5500 ext 1 [email protected]

Mine does the same in the range of 2800-3000. Sounds like diesel knock. I only noticed it recently, but it probably was just drowned out by the stereo. Glad to hear others are experiencing the same and maybe its just a normal characteristic for this motor.

Yep, I noticed this for the first time this weekend pulling the camper. Under heavy load and moderate accel. it sounds just about like a cold diesel from about 2-4k. Never noticed it the first 3 times we took the camper on a trip, but I can pick it out even without it on there now.

It almost sounds like a multiplate clutch rattling on a motorcycle if you've ever heard that, or the diesel thing.

After driving for a bit with that sound. I've found it only does it when it's 50 something degrees outside on mine. It doesn't matter how warm the engine bay itself is... which I find odd. 51 to 59 ambient on moderate acceleration.. rattle. Tune or no. Same same.
