Me no stumble now! My car was acting up for the last few months - low on power and stumbling on acceleration. Finally, it threw a code last week PO171 - too lean Bank 1.
I tried everything to fix this issue including:
1. Plugs
2. New front O2s
3. Vacume leak test - manifold, MAF
4. PCV leaks
5. Exhaust leak - head and LT collector
...nothing seemed to cure the issues.
Finally, I pulled out the old factory MAF and replaced the SLP 85MM unit I bought about 4 years ago.
Bingo - the car is running great - no stumbling at all - MUCH more power too.
