The ONE REASON Why My 25yr Old Truck Runs So GOOD!!

Here's The ONE REASON Why My 25yr Old Truck Runs So GOOD!!
#MAPSensor #SmoothIdle #RoughIdle

In this video I change a part called the MAP sensor (manifold absolute pressure sensor) amid my ever constant search for great idle. I just recently replaced the EGR valve with great results and this is just another sensor that was original to the truck that does effect idle. My truck is a 1995 GMC Suburban also referred to as the OBS Chevy or the GMT400 platform. Quickly becoming a classic, I'm always looking for ways to keep this thing on the road. But, not just on the road, on the road and running great! I subscribe to preventative maintenance all day long. My goal is to not only keep my truck running but keep it running like new. This process should be similar to most 1988-98 GMC or Chevrolet Full-Size Trucks.

As a side note when replacing parts that are still working, a person could always put the part back in the box it came in and keep all those little parts in the trunk. If a part ever did fail for some reason you'd have an immediate backup on hand that you know works.

Reality is even if this gentleman spent 5 grand fixing his 25 year old truck way cheaper than 75 thousand for a new one

[MostlyBuicks]

I agree with you MOSTLY. Often, these days, the 25 year old part may have more life left in them than a crappy new part would.

I have a 1995 GMC1500 Sierra..
250 k on this dude and it runs like a champ.Preventative servicing is the NAME OF THE GAME😊

Nothing wrong with replacing parts that are 25 years old. It makes you feel good, all the power to you. Great content as always. Cheers from Sydney, Nova Scotia

All my year 2000 and older Suburbans have hit nearly 300k miles, and taken me through ridiculous terrain and weather. I've done all of the work myself, except for a fuel pump replacement, and your videos helped me immensely, so many thanks my friend.

[sparked]

Your logic is sound. You are manifesting a perfectly maintained vehicle. Good work.

[MrBowNaxe]

I drive a '99 GMC Suburban K2500... I'm a firm believer that an ounce of prevention is worth a pound of cure! Good stuff Jimmy. Keep 'em coming....

[markt]

Spot on. If you’re handy, do it. My trucks never leave me stranded.

[chrisgraham]

Ever notice how many good reputable mechanics at small shops drive 90's cars. It's not because they are poor.

[davidtucker]

Each owner has to decide to what extent or frequency they replace parts. The older the vehicle the more sense it makes to replace iffy or suspect parts. One thing i learned early as a new mechanic, is that you never throw away a old part being replaced, not till you have the new part installed and working properly. You may have to refer back to the old part for one reason or another, and being able to do so can save you a lot of grief.

[FabiusMaximus]

People have asked me why I'm always working on my truck. I just tell them I'm making it new one part at a time.

I agree with your approach with one small caveat. You can't always assume a part is good because it's new. A lot of the parts now are made in China and can be hit or miss, even AC Delco parts.

I appreciate the warning about having a family at the beginning

[mattiasherrera]

Jimmy, I agree with you, but you missed probably the most important part: have some fun fixing things, and having the satisfaction at the end of another job completed!

[Koda-Kitikawa]

The problem is the new parts they make now days dont last as long as the originals...

[aidenstefanson]

1997 GMC Yukon owner, I think we share a similar outlook on maintaining older vehicles. Its cheaper to fire the parts cannon every once and a while, than to constantly trade up to newer vehicles like some people do.

Absolutely. A few years ago, I bought a 2004 Grand Cherokee Limited on a whim from auction and was thinking I'd just address a couple of things and flip it for a profit, but I ended up liking it, so I went through the effort of parts bombing the crap out of it as a preventative maintenance endeavor. Soooo many new parts and the thing starts, idles, and runs like a champ. One of the biggest improvements I made was having the cylinder heads redone. The heads on this engine (4.7 V8) are known for dropping valve seats, so I had new seats installed and had them peened in place as well. Those seats aren't going anywhere now. And everything else I did, it might actually be a shorter list of what I didn't replace. I'm doing something similar on the 2002 Silverado Z71 I got that was my uncle's old work truck, though mostly, that's a cosmetic endeavor as the interior was completely trashed. These older vehicles are fantastic. New enough to still be able to find parts and not be plagued by the struggles that come with carburetors and whatnot, but old enough that the parts are cheap and wildly plentiful. A couple years ago, I paid off my 2017 Mazda and I'll never buy a new car again. It's just not worth it.

The best time to buy a car is when you don’t need one. The worst time to buy a car is when you need one RIGHT NOW! Same logic here.

I'm so glad I took your advice - I switched out a MAF sensor and my fuel trims went back to normal...so happy!
