Every misfire that I've ever had on my vehicles were coilpacks :D Coming back 7 months later re reading this whole situation and laughing at myself, cause after getting the super milky oil and nearly tearing apart my whole engine in my driveways it was just bad coils in the end. A good lesson for a...

I have done a few head gaskets on Volvos - fairly straight forward. I have never seen a cracked block - only failed head gaskets. Contrary to what you have concluded from reading, the blocks are very robust. Proceed as if you have a blown head gasket, but don't order parts until you have come to a ...

Starting a new thread here for a new question, ive made a decently long thread stretching across a couple months. The issue started as an occasional low idle issue which evolved into a constant low/hunting idle issue and misfiring on cylinders 1,2 and 3. A few days ago a saw my dipstick was mily and...

Since i don't have many alternative options ive decided im gonna take it upon myself to remove the cylinder head myself, may the power of google and robert diy be on my side as I embark on this journey, I have never done any job like this before but i know how to label, take photos, and follow repai...

Welp i grabbed my scan tool from work but it was all for nothing, pretty sure the headgaskets toast. I thought my coolant level was looking low but chaulked it up to being absurdly cold. After scanning the car and seeing it had no codes other than the misfire codes, and noticing that cylinder 2 was ...

Car ran fine with denso plugs that arent even made for this year/make/model, at least for a few months. Ive seen the denso 5344s on the forum used on p3 s80s and work fine, not even sure how the hell they got put in my car. I dont think im gonna spend the 125$+ on another set of spark plugs from the...

Every misfire that I've ever had on my vehicles were coilpacks :D Could i unplug the coil for 1 and 3 and move it to say 2 and 4 and see if the misfire moves, similar to swapping the injector or plug? As long as i unplug the coil itself obviously and not just put the coil in a different hole on the...

Changed all spark plugs with a set of NGK iridiums and the car doesnt flash the CEL right at startup, however it did flash when I drove the car around the block. Not sure whats next.

Its telling you cyl 1 and 3 are misfiring, , check them, swap plugs and see if the problem follows the plugs, if not ... swap injectors and see if the situation changes. It could very well be aging injectors on their way out. if not... check injector wiring for cracks.Put a finger on the injector t...

So of course as soon as i go to test the stumble at idle the car wants to act like nothing has even been happening, no misfires or stumbling idle. Waited for the idles to drop down after start up, let it slowly drop itself down to regular idle speed and waited a few minutes and not a single sputter....
