P0021 code??
Okay, so I got my oil changed yesterday and I've been burning some oil and noticed lack in power so I also added some restore engine lubricant. I've heard and seen that it works very well. Anyhow, after driving for about 10 miles I noticed the car was doing better performance wise. But at about 12 to 15 miles it started to shake at idle just a tad. And then at 20 miles the check engine light came on sending the P0021 now since I've never used restore I was wondering if it could some how be what's tripping the code?? If not what is making the timing advanced on the car? And what's the best way to go about fixing it?
