So I found out the dizzy cap was bad, sourced one out of Cabe toyota in California. Put an all new exhaust from the manifold back, with a flanged performance cat, and new muffler.
It's running much better now but still VERY rich. I'm checking the forums now and searching for tuning advice. I know timing is way off and may still have a vacuum leak. I've covered all my bases with replacing the usual culprits on a rich mixture: plugs, filter, O2 sensor, new dizzy + rotor.
I'm wondering about the calibration on the the itb's/ecu being that I'm much higher elevation that sea level. Not sure if it could be a problem but I've heard this may be an issue from a few people.
If anyone has any tuning knowlege or has feedback plz hit me up.
Thx!
