Basically bogging.... Its been going on for while now. Between 0-3000RPM's. Once over that the car seem to wake up.
when i first checked my timing like 2 years ago found out that it was far advanced in the 20's... Around 25 actually. So bumped it down and have had nothing but problems since. So I bumped it back up and still doing it. But now its set at 19-20*. So I have been working to figure out the issues. Mostly because I'm only getting around 230 to a tank of gas about 23MPG. Which is bull crap.. At least thats what my Scan Gauge says.
As for the Scan Gauge, at idle its reading my timing at 3-8*, which isn't right at all. Should be from 15-17*. At least I would think if thats what it's set at. So from that the only thing I can think of now is that the crank pulley is coming apart.
reason for the compression test.. to narrow it down to see if thats the issue.
