You're welcome! Hope it works out.

This video just saved me hundreds of dollars

Thanks for the video. I have a 2002 and have never had this done. I'll be online ordering soon

You can pick up a cheap scanner at harbor freight for 20 bucks that will scan all your codes OBD2

Nice👍🏿 And your 200,000 plus miles & she's still running nicely! I found my 2005 up in Canton Georgia & little old man drove it & it was garage kept & she is clean on top & underneath! I changed the shocks & struts. On my second oil change to Mobile Super with all Wix filters. Fresh set of AC Delco Iridium plugs & the originals were still in the engine & none fouled 😁. Put a new Dynomax Muffler to free up the exhaust but not like a Flow Master🤮. New Tires 255/70 R16 & now I have to change the RR sway bar end link but I'm gonna change the driver side too. All in all it's in really good shape & I'm just replacing & upgrading OE parts because of age & not wear'n tare. It basically was a grocery getter! I got it at 124,000 miles last year & she's just at 133,500 since I've had it. Love these 4.2 Ltrs🥰. Stay safe & thanks for the video ✌🏿

Just watch out if you flush your engine oil. The oil pan on these is terrible to get off if you have 4x4, and if you flush and a bunch of sediment goes to the bottom, it can clog the oil intake filter located near the bottom of the oil pan and choke the engine out...thus destroying it. I know. 🤕

Listen to the man !words of wisdom.

Thank you for telling me where those 2 parts are located. Being a female, men will try to take advantage of me even though I worked in the automotive industry for 20+ years and many shop owners have told me and given me an area in their shops to work on my own vehicles.

I recently changed my spark plugs but my car still turns off when in park or stopped at a red light.. I found my next project! Thank you for sharing your knowledge! 💯

Glad it was helpful!

Also a note here, Buick Rainier, GMC Envoy, Chevy Trailblazer, and Isuzu Ascender are all the same vehicle so this works for all of them. My Ascender is at 227k miles and is having this issue to the point it surges like a cam and frequently dies while decelerating unless I apply throttle while braking.

2003 Trailblazer LT with same problem. Doesn't have a MAF sensor. I removed & cleaned the Throttle Body with gasoline and a rag. Use an 8oz of Seaform in 1/2 tank. Ran it about 80 miles over the course of 2 days. Run much better now, doesn't shut off as often while deaccelerating coming up to the stop lights or while sitting idling in my driveway. I will add the another 8oz of Seaform, this week to a full tank of gas. Hope this helps. - Peace out

@@red-hat-mike I'll do that as well then, I have MAF and MAP on the way in the mail. Couldn't hurt to clean throttle body and run a can of seafoam through it. Probably run seafoam in the oil too since I'm just a little bit til change

Get it all into the video ready to see where my map sensor is and then he goes since it's a V6.😂

Thought it mentioned that it was an inline 6 right off the bat...twice, actually.

02-05 Trailblazers do not have the maf sensor but an intake air temp sensor as well as the map sensor.

...and yes, I did have the motor mounts tested and one replaced. It made no difference in the rough idle prior to replacing these parts.

My 04 envoy has a mass air temp Sencor which is round bout 3/4 round & about 2/1/2 to 3 inches long , mine isn't flat like that , not sure what they change stuff ? Same motor & everything else on those car are interchangeable

Apparently, some have maf sensors, and some don't. Mine does not.

MY 4.2 L I6 2005 model year does not have one. Only one temperature sensor further along that air hose. Two people on the internet said it was eliminated as a variation in 2005. THE one I Bought from rockauto is going back. Thay said it would fit my vechicle. This really is true?

I have a 05 lt I do not have that on my truck I keep going to get Dino tests done they keep saying my mass airflow sensor is bad I can't find it

I wonder what codes did you get to come with that repair. When mine do that uneven idle I clean the throttle body cause these models suck oil fumes thru air intake. And every time I clean the throttle body it comes back steady

True that! I am pretty consistent at cleaning the throttle body since it's very easy to do. This didn't seem to be the issue in this case, though, unfortunately. Good maintenance though!

It's dependent on the year. My 2004 LS has an IAT and Map only.

I have the same engine an yet mine has no maf sensor

My 2005 4.2 doesn't have a MAF sensor, just IAT and MAP

If this doesn't work for you, (and you can run codes), try looking at your Evaporative Canister vent Valve back near your differential. They are about $17 at rockauto and are a VERY common issue on these and their running quality. Would also be seen under fault code p0014. Try replacing those if you never have.

I have on 05 trailblazer. Sometimes just turns off after backing out of the driveway and switching to drive. Starts right back up no problem but turns off as if you turned the key off. Think this would help?

Hmmm. I wouldn't think so. That doesn't sound very related. Do you have any lights on your dash or codes showing?

I have a similar issue with my 04. But it only hesitates (RPM fluctuates about 200 RPM) when in top gear 70-90 Km/h. No issues on high speed or idling. Any suggestion will be appreciated.

Try changing out the "oil pressure sensor". It's located right next to the oil filter. Easy fix big difference in vehicle hesitating or rough idle.
