Thank for the video! I have an '84 Caprice (305-engine). The idle is a bit rough at times, although I've been told that the carburetor needs to be rebuilt, I might as well replace the EGR. Your video showed me how easy it is to do!
Watched your video last weekend. Immediately went out to the garage and tested my egr. It’s good but tons of carbon build up. Cleaned as much as possible and vacuumed out the ports to the engine. Worked pretty good
Dude this is crazy as fuck 🙃 I watch all your 85 caprice videos, learning stuff to work on my own 85 caprice and I just spent countless hours around a month before you uploaded this specific video figuring out the EGR valve system, replacing the thermostat+housing, replacing the entirety of my vacuum hoses and 3 new sensors and set it all up to factory specs after it being dilapidated since the car was built/mechanics Making shortcuts by capping ports etc. Learned on my own about that EGR valve yeah but I sure would've loved to have this video out just a month sooner 🤣 love your videos. You have shown me sooo much more than any repair manual or internet forum. Hope you continue your 1985 caprice videos for as long as you can make them. 👍👍
And after looking them up, I can't believe the factory service manuals are freaking $75-$200!!!!! Insane!!! I always just used Haynes manuals, but they're obviously lacking alot
Nice video . Just changed the fuel pump on mine. I’m having the same exact symptoms but mine also stalls out when I put it in reverse and when I come to a complete stop sometimes. I’m wondering if this could be the issue… Bought the car with a Avs 2 Edelbrock carburetor
@therealnickd3011: those are the symptoms I had that led me to replacing the EGR valve. Other thoughts: make sure the fuel filter isn’t clogged, and check all the hoses running to/from that aftermarket carb-I’m not sure if that’s messing with any sensors. Mine still has the original connections for all the rudimentary sensors and emissions stuff.
Great video bud! I have a Chevy Caprice 1985, and all the wiring are messed up by previous owners. I need any advise to rewire EVERYTHING correctly. Any advises?
@SasiExpLosioN: thanks! The wiring is surprisingly complex in my view. I would suggest getting a copy or reprint of the shop manual, which has lots of color-coded diagrams showing all the connections. Does your car work or is the wiring so messed up that the car won’t even run?
@@LongologoProductions The wiring are messed up but the car is running, I want to make the car to manufacture status especially on the wiring. If you have any reference like shop manual it will be great. Note: I bought the car without engine, I installed a 350 v8 gasoline.
@@SasiExpLosioN : there are some shop manual reprints and CDs on Amazon - search for “1985 caprice shop manual” and see the first four or five hits. If you bought the car without the engine and put in a 350cid v8 (original police package option or after-market non-Chevrolet?) that might make it very difficult to get to an OEM state with the car. MAYBE if it’s an original Chevy 350 v8. There is info for all the different engine options, carburetor, TBI, etc in the manual such that maybe you could redo all the connections. But that sounds like it would be a HUGE project. Also, I’m not sure what the emissions components are or were in your region and maybe different. I have maintained the original emissions reducing components on mine and I can tell you there are a lot of wires and hoses for all those parts - it looks like a rats nest. But when everything is working properly it’s really smooth. Sorry I don’t use Telegram. Definitely check out Amazon or eBay to pick up a shop manual.
@@LongologoProductions Unfortunately I'm from another country KSA, and the shop manuals from Amazon and eBay are extremely expensive compared to Haynes and Chilton. Thank you very much anyway!
@@SasiExpLosioN : could you use a vpn to access eBay from a different site to purchase it and have it shipped to you? Or a family member in another country to purchase it and then mail it to you? Sorry I can’t be more help.
Do you daily drive your Caprice? If you do in a major US city, do keep it parked in a safe place where LE can safeguard it to keep roaches away from stealing it.
Thanks! It’s the 1985 Chevrolet shop manual for the Impala, Caprice, Monte Carlo, and El Camino, with the light blue cover. I have seen copies of the shop manual on eBay and on Amazon. Some are in digital form on a CD; others are reprints.
@XRubenX: It's medium brown metallic and the info from the trunk sticker is "DIS.LACQUER WA- L8593" You can see all the color options in my other video here: ua-cam.com/video/AhW1Zk08di4/v-deo.html
@Rewindto91: only in reverse gear? Not when you shift into drive? Carburetor or TBI? Maybe transmission problem or low fluid in transmission. Maybe idle air control? Or even a vacuum leak somewhere? Not sure ….
@@LongologoProductions i got the same issue mines on a 83 with a carb 305. It happens for me when I put it in reverse or drive and when I give it too much steering. I think its vacuum but it also seems like fuels not being delivered right
@@LongologoProductions no everting seems good i have a little bent in the fuel line by the carb but not a kink I've replaced every vacuum line and now I'm thinking its the car but I can't find a rebuild kit for the q-jet 1707839 and apparently you can't put a edelbrock on this motor without a ce light
@@boxchevydame : definitely a possibility, just harder to pinpoint exact cause if due to the carb. EGR valve just happened to be most likely scenario on mine, as the carb is only 6 years old. But the seals are going bad on the carb and I need to address that. It never ends…
@Walker10: At about 0:08 in the video you can sort of see it on the far left side of the screen. It’s mounted on the top of the passenger wheel well and is underneath the hose running between the accumulator and the compressor. Hope that helps.
I see you have all the emissions components and hoses still hooked up. You never thought about deleting all that and freeing up space in that engine bay??
@Max Ax: Even with all those hoses there’s still a ton of space in there! 🤣 Yeah, I thought about it but decided I wanted to keep it all original including the rudimentary emissions components. When it all works together it really runs smoothly.
@@LongologoProductions yeah I was just thinking the added power and hopefully less resistance would make it a better ride. And help my mpg which isn't that good at all. 12-14 at best mixed with freeway driving which is less than others I've heard.
@@DominiAeternum : 12-14mpg is low. What engine do you have? 305 v8 w/ carburetor? That was originally rated 17mpg city (I think). But the ethanol content in today’s gasoline where I am leads to a couple less mpg. With all the emissions stuff working and the carb tuned though I’m not that far off the original mpg.
@@LongologoProductions yeah 305 with a stock QJ 4-barrel carb. I was happy to get 1 that had the QJ because I thought it would give better mpg than the ones with the aftermarket carbs on them, and whose engines have been ran through by amateurs. Either this carb and engine was tuned too rich, or the headgasket is slowly but surely going out. It idles at like 2600 rpm I believe, think that's way too fast according to the sticker on top of the radiator cowl. Someone wanted power not efficiency with this one I believe
@@DominiAeternum : Wow that is a high idle and will cause bigger problems soon if not dealt with. I found some discussion at this link that might help: www.chevytalk.org/fusionbb/showtopic.php?tid/89019/ (scroll down a bit to where they realized the person has a carb and not TBI). Maybe that will help you?
slightly less than 4 gallons, and that it likely because our fuel is required to have added ethanol here, which negatively affects gas mileage on old cars.

I drive it periodically to keep it running. It is in daily driver status so any day I can just start it up and drive.
Thanks for the useful Videos.

@Box Chevy Dame: thanks! It made a world of difference on mine.

Can you show where your map sensor is located and what vaccum line it’s connected to?
@Walker10: At about 0:08 in the video you can sort of see it on the far left side of the screen. It’s mounted on the top of the passenger wheel well and is underneath the hose running between the accumulator and the compressor. Hope that helps.
@Walker10: Actually that's the barimetric pressure sensor. The MAP sensor is located closer to the firewall by the distributor. Sorry.
I'm shocked your intake manifold passages were not full of carbon deposits like my 305 was.
Oh there’s carbon in there. See starting at 6:07. Is yours way worse than that?
Yes, but it has a lot of carbon deposits. 190,000 miles but lovingly maintained.
