Nissan Frontier Problem Report
Nissan Frontier Internal Engine Damage Caused by Screws From Intake Manifold
Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.
The coolant outlet on the front of the lower intake manifold may develop a coolant leak.
So I checked the battery and alternator.and they both checked out good.
Was popping out of first now it won't go in but all other gears are fine.
