Kia Sportage Rebuild: Misfire Diagnosis 

Thang you!

A trick: you can watch movies at Flixzone. I've been using it for watching a lot of movies during the lockdown.

@Liam Anthony Definitely, I've been using flixzone for since november myself :D

It is an option for sure, however I will manage to find a nicely cost effective solution to the problem in the end. Stay tuned!

Shaking maybe from air mass sensor

Bad valve stem seals wouldn't cause compression loss. Bad or gunked up valve seats definitely would. Broken valves as well.

Get a scan tool that has live data -- I have a video about a foxwell one that has it. You need to view your fuel trims. Look at your fuel trims at idle and compare them to your trims at 3000 RPMs. If the total fuel trim goes down, you have a vacuum leak. If the fuel trim goes up, you have a fuel delivery problem and you'll want to check your fuel pressure and/or you have clogged injectors. Search my channel for my fuel trim videos.

50sKid Gee thanks dude. Wasnt expecting a reply due to most channels not usually responding. I appreciate your help and have to get a scan tool. Thanks again sir!!!

Chucks Stuff it’s getting really really hard at this point! Can’t respond to as much as I’d like to

50sKid haha I can imagine. Its not like RU-vids your main gig lol thanks again sir

@@50sKid Hey years later but wanted to tell you thank you for helping me with the Sportage. Turned out it was upstream and downstream o2 sensors. NOW ANOTHER ISSUE HAHA about 6 months ago I had an issue where oil had made its way into the spark plug galleys on cylinder 3and4. Replaced valve cover gasket and issue went away. On Tuesday I drove about 100 miles and noticed a strong oil burning exhaust type smell. Just checked my plugs and all of them had a goldish yellow porcelain and strap. Checked compression and found 1. 175 2 167 3 160 4 155 Going to do a leak down test to see if it’s a head issue but could you think of what would cause the oil to be getting back into the plug galley and what could cause this smell. I did notice that I drove with low oil. Just the dipstick tip had oil Yikes

Darren P, that’s a lie.

Mine is at 180 k and still working fine. It’s a 2002 Sportage.

The representative is just a disgruntled employee.

Mine has 148,000 miles and is running fine. My last Kia went almost 200k before I traded it in. The "Kia representative" is a disgruntled employee, or someone with an axe to grind.

78,000 not 77,000 or 79,000 seems like an arbitrary fabricated number.
