A dirty throttle body im my minor experience causes a screwed up idle an stalling also,,,dude your videos rock thanks

[@MattsShop]

Yea, these throttle bodies always get dirty with black oily soot. Thanks!

[@irvinlopez2351]

My truck use to stall and say engine power reduced I fixed all these parts and it ended up being the knock sensors 🤘🏽

[@MattsShop]

Those knock sensors alwas call reduced engine power.

Have a 01 S-10. 4 cylinder. It kept hesitating and wanting to stall out. Our mechanic had it for a month couldn’t figure it out. I went to Lowe’s bought 2, 1 gallon of mineral spirits. Poured the whole gallon in the tank when it had about an 1/8 of a tank. Ran it until almost empty. Poured the second gallon in filled up with 93 octane ran the snot out of it. No more rough running or wanting to stall.

Leaky fuel lines... Casuse p0300 on highway abd throwing fuel pressure regulator codes... But runs great... Already ordered steel braided kit

Since gm came out with vortec injection late 95 the after market parts just dont cut the mustard,,so he's exactly right dont try the aftermarket stuff because you'll chase the problems to death go original gm equipment or forget it

[@DRDROP-fj4bo]

What kind of little scope is that Matt? Which one you recommend?

[@MattsShop]

It's called a DSO nano, but it's really old. I'd just get the best one on Amazon right now with a big enough screen.

[@telesasmith4573]

Thanks for sharing

[@MattsShop]

Thanks for watching!

[@victor_beltran]

Good video, however you forgot to mention camshaft sensor. Was fighting a stalling issue for over 3 months. Truck would idle drive just fine until it got to operating temp then truck would just cut off. Turns out my cam sensor connection pigtail had exposed wires. Clipped out old one & replaced pigtail connection only & stall is gone!

[@MattsShop]

Yea, those can cause problems too, but I just included the most popular ones in this video.

[@victor_beltran]

@@MattsShop good deal appreciate the info!

[@evertlazaro5528]

Hi Matt my name is evert recently I’ve been watching your videos and I have learn a lot but i have a question for you have you seen or fixed a 03 Chevy Silverado quadraster running on propane ?

[@MattsShop]

Hey Evert thanks for watching. I've never worked on one of these trucks running on propane. The Quadrasteer setup in these trucks is RARE!

[@warrenscott9990]

My throttle body went bad causing truck to go into limp/low power mode. Forget the code but a new throttle body fixed all that. 04 6.0L

[@MattsShop]

Those DBW go bad and then it will throw a code for sure, but if the DBC won't throw a code. It's all the other sensors.

[@jaimea9151]

Could you make a video on fuel problems on these trucks ?! Very helpful man

[@dougedwards8022]

Love mine 05 6.0 but I really do despise no fuel filter except on the fuel pump grrrrr!

[@zmblion]

I pulled my hair out trying to fix reduced engine. Check all grounds all wires just kept getting worse. Cleaned the throttle body it went away

[@alexmixco5997]

I have a question I have a 01 silverado 5.3 when I first turn it on and give it a little gas sometimes it will stall but if I let it warm up and then drive it for a minute it won’t stall out usually only does it when it’s cold or been sitting a while no check engine light or anything no warnings lights pop up

[@ZIGZAGBureauofInvestigation]

What kind of lift kits did you do on your 2rwd ? Silverado ? I like the look/want that look on mine 2rwd stock level.

[@MattsShop]

Rough Country 3" lift knuckles and 1" metal coil spacers under the coils. Can't remember exactly how thick they are though. I did a lot of measuring to get them level.

[@wmkess]

So these trucks have IAC valves? Had an old car that burned oil and the iac was always getting gummed up and causing stalling.

[@MattsShop]

Yes they do on 1999-2002 and 2003-2007 it's built into the throttle body.

[@wmkess]

@@MattsShop Appreciate the reply. 2005 model here. Found my rough idle problem last night. My plug wires on the passenger side basically rotted from heat and one was totally broken thus no fire in that cylinder. Plan to clean the throttle body and maf next while I’m at it as neither can hurt.

[@BellaRocko]

My '03 Silverado kept stalling at idle, all due to a dirty throttle body.

[@MattsShop]

Yup, if the throttle body is bad it will stall at idle for sure.

[@Mikey-wf9py]

Do they do make an electric throttle body for the earlier denalis and escalades... It doesn't have trash control looks different I have 02 Denali... I'm pretty sure I need intake manifold gaskets... Whistle noise on acceleration and hissing in engine bay... Unless it's a/c but I just charged it and did the shroder valves and still cold

[@JayG0217]

What about stalling only in reverse? Never in drive or just idling.

[@redwolfmaddox3986]

it wasnt the MAP sensor for my 93 what should i check next?

[@deelock1605]

I changed all those sensors and then some. 08 5.3 silverado continues to stall. Shops won't run a check without a Check Engine light. Replaced O2 sensors, Mass air flow sensors, crankshaft sensor, camshaft sensor, Throttle position sensor, fuel pump, and spark plugs. Truck runs smooth until warmed up and then hesitation ensues followed by stalls. Coolant is 210 and steady. Transmission shifts smoothly but when hesitating, feels like Transmission is loose. Need help!

[@austinmangum4702]

99 chevy silverado 1500 4.8 stalls when I brake

[@ellawns793]

2004 Sierra 5.3 would stall at a stoplight ended up replacing intake gasket because of a vacuum leak took care of it

[@anthonydv0776]

If your truck has problems starting up after it’s warmed up, but no problems starting up from cold then replace the fuel pressure regulator

[@cyberplague2805]

So i have a 2004 suburban 4wd with the 5.3 just fixed an oil leak and now its stalling, if i accell too fast which really doesnt take much it stalls and cuts all engine power for a sec or if i try to go above 2k rpm sometimes i can get it anove 2k but then it will not go above 3k. Also it can rev all the way to redline in park without stalling.

[@cyberplague2805]

It doesnt throw any codes though, any ideas?

[@Mikey-wf9py]

That 8.1 is a carbon machine... It will put carbon soot marks on the snow. Had 01 2500HD regular cab

[@streightttRAWW]

I have a 04 5.3 Chevy 270k on it. I was handed it as it was getting junked by my father. I took it on as a DIY prj.. got a new battery and it kicked right on. Alot of white smoke im thinking a (blown head gasket) .. i cleaned the throttle body and that made it run in idle longer but soon as i rev the engine the car stalls. Ive noticed with the intake tube off the butterfly valve on the throttle body does not open even after cleaning... idk if thats from not relearning or just damaged. This weekend i was going to replace the throttle body, hoping this is why it keeps stalling. Also i replaced the crankshaft sensor (did not relearn) as the codes i get right now are all related to Coolant sensor and Crankshaft Sensor. PLEASE HELP

[@stevengallo8942]

5:29 love mini scope want same where can I purchase?

[@MattsShop]

It's called a DSO nano, but they sell much better ones online now.

[@dougvail9264]

Carb cleaner? I was told to use only MAF cleaner.

[@HypocriticYT]

My 2002 Camaro with the LS1 stalls in warm weather after it’s hot and turned off them on again and begin driving feels like the gas has vaporized in the line and stumbles or stalls 😢

[@famfam3404]

My 2002 L59 came with drive by wire, I guess I'm lucky lol

[@MattsShop]

Really?? You did get lucky. The DBW is better. More refined and a better idle.

[@famfam3404]

@@MattsShop yessir I think it was ONLY the L59 that had it starting in 02 but then the LM7 didn't get it until 03 like you said, but hell yea I love my drive by wire I have it tuned so it idles like 50rpm higher by my tuner and she runs good!
