Hello, if you have a rough idle, it is possible that there is some kind of intake or exhaust restriction. Or, there is some kind of imbalance in the amount of air coming into the engine in relation to the fuel. This could be due to an air leak or restriction, or a fuel pressure concern. In any case, hands on testing with a diagnostic tool and shop manual will reveal what isn't quite right when the concern happens.
There is a hose directly BEHIND the throttle body that connects to the air duct coming from the air filter box (air cleaner) .. IF this hose gets dislodged (as they often do) it will result in rough - unstable idle.
Also - Closely inspect that large air tube from the air cleaner for any signs of cracking - loose clamps etc .. There should be NO air leaks between mass air flow sensor and the throttle body. We do not know your skill level - IF not familiar with any of this - seek qualified hands-on help. â–ªï¸https://repairpal.com/repair-shopsâ–ªï¸
