I had the same problem. I changed my TB twice and it didn't fix the problem.
The problem was with the hose, specifically after the air filter. Check all the hoses after the air filter is in good condition and tightly secure all the clamps
Don't forget to go through a TB relearn process.
If this doesn´t fix your problem,
1. Check for any corrosion in the TB connector female ports. Clean it with a proper electric connection cleaner.
2. Check your battery power and alternator.
