AP2 Compression Issues
I have a MY04, and Long story short I was having a problem with my idle right after starting, it would drop to 400~ rpm then build back up to normal. I decided to test the compression ratios and came up with the following results
On the first test I just did a normal test:
1-167
2-192
3-197
4-195
After seeing the number one was a bit low, I retested and it showed a 170.
The third time I added a small amount of oil to each cylinder to see the difference and found out this:
1-214
2-218
3-220
4-220
I noticed how dramatic the number one change was vs all the others. I was wondering if anyone had any idea of where to go from here?
As for mods, it has stock internals, Fujitsubo cat back, k&n fipk and a vafc that is tuned. Any feedback would be appreciated! Thanks!
