Hey scotty, I cleaned the throttle on my cobalt. Stupid me, I didnt take
precaution. I stuck my finger in to open. Now idles @ 2000 rpm. Is it
hooped? I asked dealer to do only relearn. Didnt do anything. Do I need
more diognostics to see if toast? Can I replace it with a wrecker
throttle?? 

Scotty Kilmer says:

Learn how easy it can be to replace a bad throttle assembly on a modern
car.

Hey Scott,
I have a question about torque converter, im experiencing gear 5 to 6 shift
flare around 42mph upshift. It only flares when im light on throttle and
upshift below 2k rpm. Rpm will flare up 300 to 500 before it shifts, feel
like car got put in neutrel. I noticed above 2k rpm it will not flare. I
looking around internet and found it might be related to torque converter
locking up in low rpm? i dont know if its true, whats your take on it? My
car is a 13′ Mustang Automatic.

Colin Donovan says:

On a similar note, is there anything that is known to go wrong with a car
like my 02 Camry so I know what to look out for?

MCTeck says:

Tighten to snug? I think it needs to be torqued to a specific spec or it
could end up being too loose,or warped If over tightened.

Bill Baldwin says:

Hey Scotty, 2006 Dodge Caravan SE.

When I turn it on especially, I hear a high pitched noise, and from time to
time when driving a scratching noise. Sounds like on the drivers side. I
think the belts are getting old though.

Roberto Buenrostro says:

Nice grease mustache Mr Kilmer.

Big Guy Review says:

What the heck is the sense of replacing the throttle body yourself if you
still have to go to a garage to reset the damn thing… I am sure the
Garage will love you so much that they will charge you double to reset it.
Garages today squeeze every little bit out of every job. I can remember
when my Garage would change fuse, small lights, ect for free. now
everything has a price on it.

Scotty, when are you gonna buff that wax off around your stingray emblem?
My Ocd goes crazy everytime I see it.

27dcx says:

I would never buy a car with electronic throttle. I don’t understand how an
electric motor and wires is better than a mechanically linked steel cable.
I swear not just with cars but with everything “they” make changes just to
justify somebody’s lame engineering job.

Johny40Se7en says:

Very nice, Scotty, have you got a video for changing a fly by wire throttle
body? my car’s a bit older than this =P

Oh and it’s not modern engineering Scotty, it’s modern “brains” for you,
people who call themselves engineers and so on think they’re more special
because they make things more fussy or more complicated… stupid bell
ends.

Hi Scotty, is mixing synthetic oil into a car that takes conventional a bad
thing to do? I personally don’t think its smart. But , i hear people say
“oil is oil”
I’m repairing and replacing a lot of a blown motor head & all gaskets on a
2005 Camry 4 cylinder, with only 56K original. It was in a front end
accident b4 i bought it. Could the accident be responsible for the failure.
Any thoughts would be great. Thanks my friend, Matty 

MrRangerZr1 says:

Scotty, How do you cleaning the throttle plates on these electronic
throttle body, is there a special cleaner for hondas or i can pick any
random one.

crusherbad64 says:

It’s great how these cars are designed in a way that if anything goes
wrong, you have to go to a dealer to get the car repaired. That’s why I
like the older cars, plus its easy to mod the older cars. I drive a 96
Honda Accord with over 250,000 miles on it and its still running strong, as
long as you maintain the car, the car will work fine. Even with the repairs
I had done on the car, it’s still cheaper than buying a new car!

Ira Friedman says:

Hey scotty do u need to do an idle relearn on a modern car even when u
change the battery? 

mexy Joey says:

I have a question is good to buy Hyundai cars … Think about buying the
hyundai sonota … Will be great if u did car reviews 

Supra2jz says:

Hey Scotty, what brand scan tool would you recommend for a BMW? 1996 to
1998 e36 specifically. I look up scan tools and read mixed reviews. The
Peake Scan tool is made for the car, but it doesnt seem to do things like
live data. Any ideas? Thank you

bmwmsport11 says:

Hey Scotty, I have a 2005 Silverado 5.3L(same exact engine as the one in
this vid). There is a loud grinding/whining noise when its running. I think
the alternator bearings are bad. I’m thinking about replacing the
alternator. For some reason the whining noise varies by RPM. If I start
driving the whining noise will change.

So my question is, is alternator the issue here? or is there something
else, along with the alternator, that needs to be replaced? Does alternator
speed(if thats a thing) vary by engine RPM?

Thanks!

Scotty my 2002 toyota avalon is has an accelerated idle what does it have

WCGwkf says:

Hey Scotty, I just moved from sea level to 6000 ft and it feels my car has
lost 1/3 of its power. Is there any way adjust the air fuel ratio to get
some of that power back? I have a 2007 scion tc. Thanks!

Zachary Morgan says:

Dear Scotty, I know this is kinda off topic of the video ,but what would be
cheaper for a shop to do a Top End rebuild or just a new motor. BTW its a
4.3 TBI.

Vanuatoo says:

Hello Scotty, I’ve Nissan Pathfinder 2003 with VQ35DE engine. The car runs
fine, no CEL codes appear on the scanner, but it has some problem. When the
engine is cold, car starts fine. If I drive it some time and shut off the
engine and try to start the car, it seems to start fine but then tachometer
gauge goes down (300-600 rpm). Sometimes it survives shut off but most
times it shuts of. If I help with gas pedal when I see this behaviour idle
speed goes to normal. Is it throttle body?

Ali Ibarra says:

hey Scotty I have a 2006 malibu SS I just replaced the throttle body but
the rpms is surging up and down even when I’m driving I dint get the new re
learn process done
how much should I pay for this process to a mechanic ? just to use his
fancy computer
thanks man . 

Zack Taylor says:

I just got done cleaning mine and it idles high 2004 Hyundai Tiburon my
mechanic said it will relearn it’s self, or does it need a reset? 

Ajunja1 says:

Hey Scotty on the dashboard of this video the exclamation point was
blinking. Now my car does that and I looked on Google to see what it may
have been and I had two answers. 1. Low pressure with the possibility the
sensor is either bad or a nail in the tire. And 2. Transmission fluid needs
changing. What could be the possible problem?
Your Fan,


slitter98 says:

Thanks for the video Scotty. Can you give the year/engine on the Silverado?

Rulvar9 says:

How can I check the fuel pressure on a 2002 ford focus?

2CrazEy1 says:

Bummer, that you have to buy a $1k-2k scanner!

morenita blu says:

Hi how do I take out the threads out of the engine block where the spark
plug goes one of my sparks plugs just came right out n now I can’t screw a
new one in cuz someone put atached thread to the plug in it Is stuck in
there how can I take it out please

TheMovement85 says:

Those all purpose car auto code scanners are becoming cheaper every month,
bought one the other day for $100. If You really want to go the cheap way
and you have a good laptop computer you can just buy the OBD2 Scan Tool
software and just buy the USB adapters. The software and usb adapter will
run you roughly $100 maybe cheaper.

Scotty should host a show 

James Valenti says:

And this is exactly why I will NEVER get rid of my Ford Crown
Victoria…..Nothing beats an old fashioned throttle cable. They are far
more reliable, simple, and better. My fiancé has an electronic throttle in
her Mini Cooper….There is a delay from when I hit the gas to when the car
actually moves….Whereas on my Crown Victoria, its instant power. To hell
with modern engineering. I will take old school, reliable technology over
modern unreliable engineering any day.

Fist comment 

Ryukachoo says:

there’s probably some exotic engineering reason to have an learned idle
system, probably for efficiency reasons….its still silly

CAFE standards (what’s forcing automakers to meet pretty obscene efficiency
numbers) are making modern cars pretty disposable and horrible to upkeep.

а в какой вы стране живёте?

scott redmon says:

what kind of scan tool did you use and how much does it cost?

Zach'sGarage channel says:

It is not a modern engineering it is only Chevy’s dumb ass self.

rudyd13rd says:

Hey scotty im a new subscriber can you please let me knoe whats my cars
problem i uploaded tha video on my channel just click on my youtube logo
and please comment that would help out so much happy thanks giving

Djonkie Bonk says:

Another reason why GM sucks. God they’re horrible and the latest thing with
the ignition systems is just deplorable.
