WTF.
And charge $882.00 to drain the fuel and change plugs. Robbery.

i’m 21, so they might just assume i’m a moron..... they said those plugs are fouled already and i said i know because i saw them when pulling them for a compression test. i had ran the car for maybe a minute while checking the wiring after installing them. He basically explained that they need to do their own diagnostic of the car, even though i did mine.

I daily drove a 72 karmann ghia for 3 years before i got this car. I know this is a totally different animal but i do know my way around a car.

Yes I think you do very well for a young fella.
I never take a car to a shop unless it is a recall situation.
So some of the thing shops do and the price they charge seems crazy to me.
I understand that they want to do there own diagnostics of the car.
But in the end it is still about the bottom line.
I also understand that they have to make a profit to stay in business.
But to me $822.00 to drain the tank and change plugs is nuts.

The real issue is your engine.
You say the plugs were fouled when you pulled them to do the compression check.
How were they fouled????
wet oil? black carbon? black carbon with sort of a powdery look ??
Grayish with sort of a powdery ash look???
Just trying to get a feel for what happened based on any info you have

I’ve been burned by shops twice, and those were the last time i took my cars to anyone.

I installed a set of e3s out of curiosity in january and kind of forgot about it because the car ran well, and then re installed the lightly used berus that had maybe 2k miles on them last weekend. the e3s looked strange when i pulled them and i’ll post a photo if i can figure it out. i tried spraying sea foam into bank one from the intake boot (the one that connects the tb plenum to the runner with the hole for the valve) but never ran the engine enough to get it all through the system. I was trying to determine if it was a fuel issue by seeing if cylinders started firing when i sprayed it in (they didn’t)

But they looked wet, smelled a little oily, and a little like fuel and the tips were dark. looked a little like carbon to me but that could have been the sea foam loosening up deposits from the head and piston.

When i installed the berus they looked perfectly grey/tan and i’ll also attach photos if i can figure it out

So just spit balling here.
I would expect the plugs to be wet because of the Sea foam.
I would expect them to smell a little like fuel because the fuel/air mixture was not burning due to no compression.

Smelled a little oily hmmm and looked a little like carbon.!!!!
I would expect a little carbon if those Cylinders were getting a little oil in the fuel/air mixture when the engine was running.
carbon=burned oil.

Was your exhaust ever blueish or whitish or not looking right???

Only when the aos failed. And then the replacement failed two months later. Nothing visual out of the exhaust, and i would have seen it because it’s a “race” exhaust.
There’s always a film of oil in the intake from the AOS. it wasn’t like that when i bought the car (it was bone dry inside), but i could never quite figure out why it never went back to having zero visual oil in the intake after replacement. maybe just an inferior part to the original i suppose, but good enough to pass.

My intake always has a little oil as well.
I get the bit of blue exhaust on startup but just for the first few seconds.
My plugs always look like they should though.

keep us posted

I’d rarely get blue on startup unless i parked on a steep hill and even that was rare.

hopefully i’ll find out something new tomorrow, and really hoping it’s something good
