Topic: 22re stumbling issues

[GRSJetsFan]

Hey guys, I just rebuilt the 22re engine in my 93 4runner and ive been having issues with engine performance. I got the long block from a local shop and replaced most of the sensors. When I goose the motor it climbs to about 3-4k RPM and then starts stumbling and will not accelerate further. When I pulled the head off there was alot of carbon deposits, much more than should be expected for only 2k miles. The timing is set 8 btdc (low end cam installed and called for +2 degree advance). Everything else is stock on the motor. Please help.

thats not enough timing for a 22re, i belive stock is 12* with the test terminals jumpered.....

instantly, to me, sounds liek a timing issue, when my 22r did that, it was due to the cam tooth skipping out of sync with the crank or vacuum issues

Well Im still having the same problem with the timing advanced. So what next?
