It's hard to tell, really. My CEL would blink when I was EOC'ing and I've had to replace 2 parts that would be associated with damage related to EOC'ing via key-off.

The spark plugs that were fouled undoubtedly had an incredibly low amount of mileage on them and I have heard theories on this forum about keying off resulting in fuel being sprayed into the engine. (These were dismissed by naysayers, but it appears to be true in my case...)

It was the same with my older cars. I lost power steering, but didn't care. For some reason this car just doesn't like me.

So, is this when you key-off? Or...? I'm not sure what a FAS board is called and I'm not that technically sound

Hmmm. This hesitation was an incredible amount of jerking and wasn't JUST after turning the motor back on.

I feel like it's hard to tell. I guess it could have been carbon but I dunno. I feel like he would have been able to tell the difference between the two? Maybe I'm putting too much trust in my mechanic.

Not attempting to be harsh, but I've taken WAY too much information on this forum as truth, only to find out it's not true.
